Competitive advantage thanks to quality improvement of the final product
The Rockster Duplex plant R1200D/R1100DS jaw/impact crusher plays an important role in the flexibility of the gravel quarry. Equipped with the unique, patented Duplex system, the crusher can be quickly modified from jaw to impact crusher and vice versa. This allows them to react quickly to the different demands of their customers. With this flexibility, it is easy for the Casaccia gravel quarry to supply a perfectly defined standard and specification-compliant final product for its customers and partners. Lorenz Biedermann, Swiss distribution partner of Rockster, explains his customer's decision for this Rockster crusher: "They primarily chose the Rockster plant because of the Duplex system. It allows them to define the final grain faster and better, thus improving the quality and providing a noticeable competitive advantage."
Use depending on the feeding material and desired final product
For a 100% defined final grain, the optional screening system for the R1100DS/R1200D is used. Any oversize grain gets back into the feed hopper via the return belt. For primary crushing operations in natural stone processing or for a desired final grain with very low fines, the Rockster plant is used as R1200D jaw crusher, while the R1100DS impact crusher is primarily used for finer crushing and recycling of concrete or demolition material.
Mobility as a further acquisition criterion
C&D processing is not only done in the gravel quarry, but also directly on the construction sites of the Hartmann group. This requires mobility says Lorenz Biedermann: "Another advantage of the Rockster crusher is the low weight and compact transport dimensions. As a result, the crushing plant can be easily transported to a wide range of construction sites and put into operation quickly."
