To guarantee versatility in their crushing plants, and optimise machine utilisation, Rockster developed the unique, patented and highly versatile Duplex System which enables the customer to change the single crushing units.
Both unit can be installed on the same chassis and changed from jaw crusher into impact crusher in shortest time – and vice versa. So the track-mounted impact crushers R900 and R1100DS can also be used as jaw crushers R800 and R1200D – and of course the jaws can be used as impactors. The impact and jaw crusher units are installed fully hydraulically and based on the same basic chassis. The hydrostatic drive system allows a clockwise or anti-clockwise operation of the crusher. So it is possible to install both crushing units on the same basic frame.
Thanks to this system the recycling plant can be adapted to a wide range of material requirements quickly and efficiently, thereby cover a huge variety of applications.
