"New dimensions in the mobile crushing technology", was the statement of many customers when they saw the new R1000S at the first time
Rockster is now presenting with the R1000S a wothy follow-up model of the track-mounted impact crusher R900 - with more technical features.
The new impact crusher fills the requirements of the customers to an increased operating and safety comfort and includes following refinements: a new developed multifunctional color display, an auto start and stop function, a stepless variable, fully hydraulic gap adjustment with integrated measuring system as well as the automatic load-dependent, stepless regulation of the conveying speed and a new fixed hammer. Also the hydraulic vertically adjustable magnetic separator, the hydraulically lowerable screenbox and the swiveling catwalk make the maintenance of the machine easier. The versatile setting options and the two-deck pre-screening with a screen mesh provides excellent quality. The up-and-over lift system of the side and back doors ensures event greater free moving space and saves additionally space.
THE R1000S IN DETAIL
The vibrating pre-screen chute is resonating to stop deposits in the shaft. The vibrating discharge chute is transporting the material on the main conveyor and prevents the wear of the belt - this will significantly save wearing costs. The inlet width of barely one meter and the oversized rotor diameter of more than one meter guarantee the best throughput rates in the different applications. The blow bar exchange is also possible with a built-on hammer exchange device, an external lifting device is not necessary. The hammers are available in different quality levels. The optional screening system - consisting of the compact circular vibrating screen RS100 in combination with the patent protected double functional return belt RB92 - is the perfect complement for the track-mounted compact crusher R1000S for creating 100% defined final grain. Furthermore the hydraulically lowerable screenbox make the mainenance and service easier.
FROM TRANSPORT TO WORKING MODE
Because of the compact transport measurements - lenght 10,10 m, width 2,55 m and height 3,2 m - and the weight of 30,4 tons, it is possible to transport the Rockster R1000S without any special authorization. It takes just 10 minutes to unload the impact crusher and to put it into operation. If the transport includes the optional screening system the dismantling of the return belt and screen box is not necessary. It is also possible to transport the machine with screening system without a specifically required authorization because of the transport measurements - lenght 14,00 m, width 2,98 m and 3,2 m height.
Rockster demo show 2017 / CHINA
ROCKSTER DEMO SHOW CHINA 2017 was successfully held in Chengdu in January
On 11th of January 2017, the first Rockster demo show in China has been organized in Chengdu at the Rockster customers location, a beautiful place in South West China. Altogether around 80 dealers and target customers coming from all over Chinese provinces and areas joined this event in Chengdu.
In order to share the Rockster product design and development history with all the visitors, the demo show was started with a historical and technical presentation from Mr. Wolfgang Kormann, the CEO of Rockster headquarters. After the presentation the demo show on site was opened with the first demo job: the impact crusher (R900) combined with the scalper (RSS514) for recycling construction waste existing with lime stone, concrete and asphalt with about 40% fines. The scalper is still a relatively new product and is gradually being known in China. The material was firstly fed into RSS514 and separated into 3 different sizes: 0/32, 32/70 and over 70mm. The material with the size over 70mm was directly fed into the R900 through the main conveyor of RSS514 and finally proceeded into the final product size of 0/32. Through the demo job all the visitors have seen how the Rockster equipment could recycle the waste material into 2 different fine product sizes which could be reused for the road basement, construction basement and parking place, etc.

Besides the introduction of the new products, the continuity, stability and high efficiency of the working process of impact crushers R1100 and R900 has been also very successfully presented at the demo show. R1100 was operated by the end user with his daily production. The machine runs at least 10 hours a day and recycled concrete for the time being and the end user is very satisfied with the high quality cubic fine material which brings him high profit every day. Meanwhile all the visitors were deeply impressed by the output of R900, which is the most compact mobile crusher besides R700S in China.
The demo show came to a successful and satisfactory conclusion with a dinner party for all the visitors and the whole Rockster team. The valuable communications and discussions was highly appreciated since it helps for their New Year´s business plan and decisions. Wolfgang Kormann thanked all the guests and promised to arrange the next demo show in China again soon.

R800 - Auto-Bau Polen
ROCKSTER R800 IN POLEN
Die Firma Auto-Bau aus Polen hat sich zu einer sehr lukrativen Investition entschieden
Das junge erst im Jahr 2011 gegründete Unternehmen entschied sich in einen raupenmobilen Backenbrecher R800 von Rockster zu investieren. Auto-Bau hat sich im vergangenen Jahr auf den Abriss von Gebäuden und alten Firmen spezialisiert und erweitert konsequenterweise seinen Maschinenpark mit einer mobilen Brechanlage. Das daraus gewonnene Endkorn (0-40) wird für den Unterbau von diversen Tragschichten wiederverwertet und somit zu 100% recycelt.
Neben anspruchsvollem Bauschutt-Recycling ist der Brecher R800 auch für Anwendungen im harten Naturgestein hervorragend geeignet. Der R800 ist einfach zu transportieren, kann in kürzester Zeit von einem Einsatzort zum nächsten gebracht werden da keine Sondergenehmigung für den Transport nötig ist.
„Überzeugt hat letztendlich das Rockster-Duplex-System, bei dem der Austausch der Brechereinheiten – Prallbrecher gegen Backenbrecher – auf nur einer Maschine ermöglicht wird. Das erweitert in Zukunft unser Kundenpotential und erhöht somit die Auslastung der Maschine“, sagt der neue Eigentümer. So kann innerhalb weniger Stunden von einem R800 Backenbrecher auf einen R900 Prallbrecher umgerüstet werden.
„Wir planen für die Zukunft das Duplex-System zu nutzen um unseren Maschinenpark noch weiter auszubauen.“ hat die Auto-Bau bereits unserem polnischen Händler DOZER mitgeteilt.
R900 - Iwersen Germany
Well proven - reinvested
After 10 years and about 8000 operating hours, it was time for a new acquisition
The company Iwersen Recycling-Transport-Civil Engineering from Schönhagen (Northern Germany) was founded in 1984 by Matthias Iwersen as single company and has expanded its portfolio constantly. The main business segments include demolition, construction waste recycling, sewer works, all types of earthworks, gravel and construction machinery transports.
Early recognition of the advantages of construction waste recycling
"In 1997 I bought the first stationary diesel / electric jaw crusher, for that time it was a very modern machine. We have quickly realized that construction waste can be a valuable product and therefore some years later we did also invest in a mobile crushing plant", Matthias Iwersen says.
In the year 2006 the company chose to purchase the Rockster R900 impact crusher, its compact dimensions, the screening system and outstanding price-performance ratio convinced the entrepreneur. "After several machine demonstrations from leading manufacturers, we chose the Rockster crusher because the performance was great and despite low transport weight of under 30 tonnes the crusher had a well distinguished screening system, so we could classify our final grain perfectly," he tells.
With the mobile crushing plant including screen box and return belt Iwersen could crush asphalt, rubble, concrete or virgin stone locally at the customers jobsite or quarry and produce reusable and valuable material. This cuts landfill fees on the one hand and saves natural resources on the other hand. "Over 10 years now we are able to meet the needs of our customers very flexibly and can offer an all-inclusive package, as well as just renting the mobile plant."
Investment in new R900
After 10 years Iwersen can look back on a reliable and uncomplicated machine and beginning of 2016 he decided to buy a brand new impactor R900 with screen box and return belt from Rockster dealer Meldgaard A/S situated in Aabenraa/Denmark close to the German border.
"We were careful with our crusher, did regular maintenance and service works and were really very satisfied with the performance of the old plant. For us the big advantages of investing in the same crushing plant are that all employees know the machine very precisely, we can use existing wearing parts and can avoid machine downtimes. Moreover the new R900 needs less fuel for increased output, it has a stronger impact plate in the inlet, the sealing of the main conveyor was perfected and the magnet is now mounted on a flexible suspension."
For better maintenance and replacement of the screens Iwersen installed 2 hydraulic cylinders on the screen box.
Differentiate with experience
Main clients of Iwersen are civil engineering and demolition companies, but also agricultural enterprises, which reuse the recycled material themselves.
Most of the time Iwersen and his team recycle demolition debris with the R900, removing earthy material by the pre-screening system and the side conveyor and removing metal by the magnetic separator.
"The favored final fractions of my client base are 0-32mm or 0-45mm, which can be used excellently as frost protection and gravel layers in road construction," explains Iwersen.
His customers appreciate the experience and reliability of the company, so they were able to grow in 3 decades from a single to a medium sized company with very qualified and dedicated employees.
R900 Special construction for coal crushing
R900 special construction for special application
Impactor R900 was customized for coal crushing at the harbor of Latvia
For a client situated in Ventspils in the west of Latvia, Baltic Service (Rockster dealer in Baltic states) needed an impact crusher individualized for extraordinary requirements in coal crushing at a harbor coal handling terminal.
“Our client has to handle an increasing amount of coal transit and therefor he needed additional crushing equipment. The coal comes from Russia in bigger fractions containing metallic parts. It is crushed to fine grain, according to the different needs of the clients and separated from metal what’s essential for high quality coal, before it’s transported to Western Europe by vessel,” says Karlis Vecbastiks, sales manager at Baltic Service.
Austrian quality mixed with flexibility
“We chose Rockster because it’s an Austrian high quality manufacturer with a lot of experience in developing crushing solutions. We really like the hydraulic concept and the Duplex system,” says Vecbastiks.
Due to the hydraulic concept of Rockster machines, the speed of the crusher, the conveyors, the screen, etc. can be continuously adjusted, so it is simple to adapt perfectly to every material and grading.
The crusher is also very easy to operate and maintenance work on the machine can be done quickly and effectively. With the Duplex-System, Baltic Service is able to change the R900 Impact Crusher to an R800 Jaw Crusher within a few hours. So the range of applications gets wider with only purchasing an additional jaw crusher unit, the basic machine stays the same.
Modification of the R900
Another reason why Baltic Service decided to focus on Rockster crushers was the possibility for individual modifications on the machine.
Rockster’s technical department developed supplements for the R900 crusher like the extended hopper walls and designed a new system for using the return belt as stockpile belt. These modifications were important for the customer as the crusher is fed using portal cranes, where the clamshell grab capacity is about 9m³. In open position the grabs are much wider than the standard width of the hopper, so the extension of the hopper walls solves the problem of material overflow due to this heavy duty application.
Moreover a stronger magnet was required, and the solution has been found very quickly.
Screening system to define final grain
The production of coal depends on many different requirements specified by the coal owners and the end users. “The finest required fraction at the coal handling terminal is 0-10mm, this is what we receive through the screenbox from the main belt, grain with a diameter of about 10-32 mm is led via the oversize belt to the stockpile belt.
The optional screenbox is crucial for us to get exactly defined final grain,” explains Vecbastiks. With the modified solution of the return belt, it is very simple for the customer to use it as return as well as stockpile belt.
R700S - Crushing Metallurgic Coke in Colombia
Rockster continues expansion plans in South America
Tough recycling project in Bogota – R700S crushes hard metallurgic coke
The new Colombian Rockster dealer Sanymaq, specializing in both the rental and consignment markets, has ventured into some very interesting recycling projects and purchased a Rockster impact crusher R700S recently.
“Our main activity will be relying on Austrian technology to venture into areas where no other Colombian company can compete”, says Mr. Jose Saturnino Barajas, owner of Sanymaq.
“There has been a new recycling law just signed in congress which requires all companies in Colombia to reuse and recycle skip and demolition waste”, he adds.
Recycling of metallurgic coke with the R700S
One of the newer projects Sanymaq is working on is the emerging metallurgic coke recycling markets. There are many smelters and foundries that have never recycled before and the new law is requiring them to recycle coke waste.
By using at first a 2 deck screen to separate the coke material combined with the Rockster machine as an oversize reducer, Sanymaq is able to get 2 grades of clean material which is required.
“Two grades of clean cubic material is what we were looking for, so we can sell the aggregate for road base material”, says Barajas.
The metallurgic plant gets the recuperated metal fraction which is also paid to Sanymaq a per tonnage price to reuse in their smeltering process.
Bauma 2016 - Rockster presents its technological progress
Among many special features, especially the new R1100S attracted the attention of Bauma visitors
From 11 to 17 April, the international construction trade fair of superlatives took place as every 3 years in Munich (Germany). Covering an area of approximately 605.000m²/150acres, 3,400 exhibitors showed innovative impulses for the construction industry. The Austrian manufacturer of mobile crushing and screening plants Rockster Recycler showed great new features at this year's Bauma and was rewarded with excellent feedback and new customers.
On almost 400m²/4,300ft² Rockster presented its current portfolio, live on the show the team presented their mainly sold impact crushers, their biggest one, the impact crusher R1100S and the smallest one, the impactor R700S. Both crushers could convince the visitors with sophisticated technology, the double functional return / stockpile conveyor, various options and the intuitive new display with quick start function. Above all, in terms of transport dimensions (R700S: 19,3t/42,600lbs & 3,1m/10.2ft height, R1100S: 32,9t/72,600lbs & 3,2m/10.5ft height) Rockster’s designer team considered the needs of the customers, who want to transport their machines as easy as possible and without special permits.
The new Rockster R1100-range – R1100S, R1100DS, R1100DE – flexible, powerful and equipped with unique features
The current Rockster R1100 portfolio can meet very particular customer requirements, starting with the base system designed with an optimum transport height, or the flexible Duplex solution, up to the extremely fuel-efficient hybrid system.
With the continuous development of the R1100 series Rockster stays on a trend-setting path. Especially this range with an inlet opening of 1100 x 720 mm (44 x 29 in), a massive rotor and a crusher outlet height of about 700 mm (28 in) has good opportunities in the market. “With our progressive technical solutions like the patented Duplex system, the double functional return belt or the first hybrid impact crusher worldwide we can more and more underline our competitiveness compared with national and international companions in the market. All these features are possible with our R1100 range," says Wolfgang Kormann, CEO of Rockster.
Ready for operation by touch of a button
The impact crushers of the R1100 series are already equipped with many new features, such as the fully hydraulic crushing gap adjustment, the new central control unit or the new radio remote control with display. Very quickly you find the most important operating parameters such as the rotor, feeder or motor speed and can easily adjust them. Moreover, the automatic mode, a quick-start possibility for bringing the system automatically into operation mode, can now be started by remote control as well. The central control unit shows a schematic layout of all processes, which enables a very intuitive machine handling. Not only the conveying speed can be controlled continuously, but also all parameters are separately adjustable, such as crusher speed, speed of vibration feeder, main conveyor, fines conveyor, etc. In addition, the display provides the possibility to save presets for up to 3 different feeding materials.
New Tier4f engines deliver more power and are environmentally friendly
Rockster did a redesign of all machines and can now offer all of its plants both with Tier3, and with Tier4f engine. Experience to date with the new Tier4f engines show that the higher power (23kW / 32hp) has an appreciable effect on the crushing operation. The machine is starting faster, a lower crusher rotation speed is necessary and requires less fuel. The crusher runs smoother, is quieter and the integrated AdBlue system reduces the emission of toxic nitrogen oxides into the atmosphere significantly.
More output through larger screening surface
Also screen box and return belt for the R1100 series were further improved. The new screen box has been extended by 500 mm (20 in) and the hydraulic cylinders for lowering the screen box facilitate maintenance, cleaning or exchange of meshes tremendously. The patented return belt RB95 can also be used as a stockpile conveyor with a discharge height of about 4 meters (13 ft). Disassembly for transport is not necessary, which in turn ensures a rapid set-up time after unloading.
Rockster at the Bauma
In hall B2 at booth number 214, as well as at the outdoor area 12B.2 and 12B.6 Rockster will present the latest developments at the world’s biggest exhibition for construction machinery, the Bauma in Munich.
Concrete crushing with the R1100D
Recycling of 100,000 tonnes of highway concrete
"Polixmair Aufbereitungstechnik" sets new benchmarks in the handling of major projects
"Greater flexibility, higher performance, faster implementation of large projects" – this is how Ferdinand Polixmair describes the challenges of the increasingly fast-moving mineral processing business. With 8 employees and a very remarkable machinery fleet, the Polixmair GmbH from Gmunden can compete in the market very well. "We can handle up to 4 major projects in parallel, we have the team and the machines available. Moreover we have no regional restrictions, we cover whole Austria, " explains company owner Ferdinand Polixmair.
Third Rockster crusher in the machinery fleet
By the summer of 2015 Polixmair had 2 out of 3 mobile crushing plants in operation from Rockster. "We have been working with Rockster crushers for about 2.5 years and are very satisfied with the equipment. The two R900 impact crushers are very quick and easy to transport on our own truck, making us flexible and quick in setting up," says Polixmair. Since the mineral processing business is hard and the company doesn’t want to reject projects, the family decided to purchase an even bigger Rockster crusher. Already during the Mawev show in March 2015, they checked out the R1100 series of the Austrian crusher manufacturer and decided some months later to buy an R1100D. It has a significantly larger feed hopper, a 200 mm wider inlet opening and a higher throughput compared to the R900. "To avoid complicated special permits for transport we were looking for a plant with less than 40 tonnes, but still providing good performance. This goal was definitely achieved with the R1100D. With use of screen box and return belt we crush on average 200 tonnes of asphalt per hour to 0-32 mm and about 150 tons of concrete to 0-32 mm. The magnetic separator works properly and the final grain is of excellent quality," explains Polixmair.
Recycling of 100,000 tonnes of highway concrete
A big current project is the reconstruction of the highway A10 in Salzburg, where 100,000 tons of highway concrete need to be recycled. Polixmair got the contract and is currently preparing 5,000 tonnes of concrete per week, producing high quality final material with 0-32mm, which is used for stabilization and fillings in road construction. The project will continue until the summer 2016. "Our new Rockster plant is even more efficient and can handle larger projects in a shorter time", says Polixmair.
Recycling in accordance with the highest standards
Neuberger produces best quality grain with crushing and screening equipment of Rockster Recycler
According to the motto "We move mountains!" Alfred Neuberger and his team set benchmarks with almost every new project. The company which has 22 employees is specialized in a variety of fields such as demolition, recycling, landfill, earthworks, slope construction, etc., and it has a considerable fleet of construction machinery. Since the '60s the family owns a large gravel pit in Ehrwald and for recycling of construction waste and RAP the company has a landfill with a volume of 400,000 m³. "Since 2012 we use a Rockster scalping screen RSS49, mainly in our gravel pit. Until this summer we regularly rented crushing plants from Haberl Construction machinery, but we decided to buy our own R900 Impact Crusher," says owner Alfred Neuberger. With the crushing plant they mainly recycle demolition waste, concrete, asphalt, as well as natural stone such as limestone.
Decision for new R900
"We had been renting Rockster crushers from Haberl Construction Machinery for years and are convinced of the performance of the R900 impactor. The new Volvo engine with emissions standard is running even more smoothly and the fuel consumption decreased by about 15% compared to the older machine. Especially the consumption per ton is really impressive," says the entrepreneur. Main fields of operation for the mobile Rockster crusher is recycling of demolition waste and concrete to 0-63 mm for material base in road construction or backfills in building construction, as well as recycling of RAP or natural stone processing.
Current Project in Asphalt-Recycling
To reconstruct the tunnel portal ‘Lermoos’ the road top layer was milled off and resurfaced. Neuberger and his team recycle the old asphalt and crush it to valuable grain with 0-16 mm in A + quality for road construction.
Styrian demolition specialist Fix Recycling relies on Rockster crusher

Pioneering a new and better way of doing business, that’s the goal of Mfangano Solution situated in Johannesburg, working with municipalities and contractors to deliver the right recycling machinery, at the right price, with the best environmental performance.
6 Rockster impact crushers R700S for Pikitup
Beginning of this year, James Kamau sold 6 mobile impact crushers R700S to PIKITUP, Johannesburg's official waste management service provider. Pikitup services the entire 1 625km² that is Johannesburg, keeping the city clean and preserving an attractive and hygienic environment for residents and visitors.
They use the Rockster crushers for producing recyclate used in roads construction and other carbon-based materials. Landfills should be minimized, they want to establish processes of recycling and immediate re-use of the final grain on site. Additionally, transport costs and associated pollutants can be reduced.
High quality crushing on limited space
The Rockster R700S mobile impact crusher was specially developed for jobsites with limited space, as is typically the case for metropolitan municipalities. “The well definable final grain was another argument for purchasing a Rockster crusher. The hydrostatic drive allows a continuous adjustment of the crusher speed and therefore guarantees an optimal modification of the final product,” James Kamau says.
Not only are Mfangano Solution’s products like the Rockster crushers environmentally friendly by design, they also provide a valuable service – through the promotion of the secondary resources economy. The benefits of stimulating this sector are well documented, in that it saves costly landfill space, enhances GDP, and creates jobs.
New R900 for Grillenberger
New Rockster Impact Crusher R900 For Grillenberger Tief- & Straßenbau
The family company Grillberger Tief- und Straßenbau GmbH from Heidenheim (Bayern) is particularly specialized in civil engineering and road and building and crushes limestone in a nearby quarry for the production of large stone-blocks, as well as for mineral mixtures. The new R900 will be at the quarry, but also in operation with any recycling of debris or old asphalt.
With transport dimensions of 9.6 m long, 2.5 m width and 3.2 m in height, and weighing 25.2 tons, the plant is compact and easy to transport, without special permits. Depending on customer requirements the R900 Impact Crusher is available with Volvo Tier 3 engine (200kW) or Volvo engine Tier 4f (210kW). The standard equipment includes a permanent magnetic separator, a side belt (with bypass chute), the remote control, the sound proofed housing, the dust suppression and the automatic overload protection. With its 2 hydraulically adjustable swing beams and the simply and infinitely adjustable crusher speed you get optimally defined final grain.
Van den Brink and his 4-member team are specialized in earthmoving, demolition, paving and much more, and have many years of experience in mobile crushing. His aim when buying a new machine was a 100% increase of the production volume. This objective was reached by the R1100DS and even exceeded.
100% more performance promises 100% more profit
Almost all operations with crushing plants are calculated per tonne of final material, therefore the optional weighing system was essential for Van den Brink. The majority of his jobs are in the contractors business for demolition waste and RAP. It’s very important for him to easily move the plant from one jobsite to the other. Thanks to compact dimensions and weight he manages to transport the crusher without any permits, also including screen box and return belt without disassembly on a semi-trailer.
A main reason for choosing a Rockster crusher was the ease of use and the good accessibility, so any maintenance work can to be carried out quickly. "The hydraulic drive, the continuously variable rotor speed and the sophisticated screening system convinced me immediately. I can therefore adjust the quality of the final grain to my customer’s requirements very accurately. The machine also features an innovative main belt wear protection, which guarantees the durability of the belt", says Van den Brink.
Innovative Recycling Project In The City Centre Of Beijing
Rockster impactor R700S is the first crusher working in the centre of China's capital
There are strict guidelines for building in the centre of Beijing, mainly dust and exhaust gas must be minimized. The company Beijing Yu Long Environment Protection was the first one doing a Recycling job here in Daxing. They used a Rockster Impact Crusher R700S which did a great job.
Processing and recycling on site
For the first time recycled asphalt and concrete were crushed directly at the jobsite and reused immediately for road construction.
Mr. Huang, manager of the company Beijing Yu Long Environment Protection, says: "The final material produced with the Rockster R700S has an excellent quality, the cubic grain can be optimally used for road construction or any other building materials." He is proud of his first downtown recycling project, processing remarkable 5,500 tons of feeding material. Thanks to the immediate reuse of the crushed material for the construction of the new road, they could additionally save high transport costs and avoid exhaust gases.
Compliments for performance and additional dust suppression
Rockster's R700S did a great job and had a very constant output (more than 100 tonnes per hour to a size of 0/32mm) and low fuel consumption. Moreover they were highly impressed by the additionally attached dust suppression on the main belt, which has been specially assembled for such conditions. Throughout the whole recycling process hardly any exhausts or dust emissions were produced.
Recycling potential in Beijing
Mr. Wang, project manager of Beijing City Road and Bridge Construction Group, says: "It is very important for us to recycle construction waste. So we can protect the environment and save natural resources." It is estimated that only in the city of Beijing, about 40 million tonnes of demolition waste could be recycled with a crusher like the Rockster R700S and about 90% of this rubble could be reused. These figures are impressing and show the big potential for recycling in China.
On Beijing TV, the project is explained in detail and the benefits of the construction waste recycling are highlighted:

Absolutely unique technology
Rockster's R & D department has developed a worldwide unique drive concept together with European experts of hybrid solutions. The heart of this concept are the so-called power caps, energy buffer with top capacities, which store electrical energy to cover any peak loads. The diesel engine operates nearly constant at optimal speed to drive the generator for the electric motor and does consequently save fuel. The permanent-magnet technology also guarantees lower energy consumption, improved engine and generator performance, and higher power density. With this technology, you can save approximately 16,000 liters of diesel at an annual use of a machine. The energy storage concept would also allow a smaller engine, but because an additional objective was to increase the productivity despite fuel savings, a common CAT 242kW engine is used. This synergy results in a considerable increase in performance and thus significantly more output.
In one of the largest construction companies of France, the Hybrid Crusher is already in use for 1.5 years and does a good job. Operations manager Laurent Perraguin says, "We produce up to 450 tons per hour of recycled demolition material, which is almost 30% more than we had before, the performance is very stable, and the fuel required could be reduced by 30%."
