Optional Screening System

Screenbox RS83 & Return belt RB75
The optional screening system - consisting of the compact circular vibrating screen RS83 in combination with the return belt RB75 - is the perfect option for the track-mounted R800 to ensure 100% defined final grain.RS83 Screenbox
- for producing defined final grain (depending on mesh sizes)
- Screening surface: ~ 2,2 m² / 23.7 ft²
RB75 Return belt
- for returning the material back to the feed hopper

DUPLEX-System: One machine - unlimited possibilities!
Within a few hours the track mounted crushing plant R900 can be changed from an impact crusher to a jaw crusher (R800) - and vice versa.
Therefore the plant can be optimized to the different requirements of the feeding material and guarantees a versatile operation.
Both crusher units (R80 and R90) 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.
