The Original DUPLEX-System (since 2004)

DUPLEX-System: One machine - unlimited possibilities!

In order to optimize the machine utilization and to guarantee a versatile operation of the crushing plants, the Rockster team has developed the
unique and highly versatile Duplex System which enables the customer to change the single crushing units.

Both units 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.

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.


Significant Increase in Crusher Utilization

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. 

Therefore the plant is applicable for a wide spectrum of operations and the machine utilization is maximized.

The Rockster impact crusher guarantees highest performance at a very high crushing ratio. Due to 2 hydraulically adjustable swing-beams, as well as variation of the rotor speed, the final grain can be optimally influenced. The quality of the hammers is chosen individually, depending on the application and can be used bilaterally.

The hydraulic adjustable Rockster jaw crusher is the ideal solution for all operations requiring highest demands on the wear parts. Even under toughest conditions the jaw crushers R800 and R1200D guarantee highest crushing power and lowest wear.
