R900 Track-Mounted Impact Crusher

THE COMPACT CRUSHER - THE OPTIMAL CHOICE FOR A VARIETY OF APPLICATIONS!

The fully hydraulic, track-mounted impact crusher R900 is ideal for flexible recycling applications with asphalt, concrete and demolition debris. Furthermore it is used for jobsites with heavy virgin stones.

The mobile crushing plant R900 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.

Optional DUPLEX-System:
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 and  the machine can be chan-ged from impact crusher to jaw crusher - and vice versa - in shortest time.

Optional Screening System for Closed Circuit:
The screening system consists of the compact circular vibrating screen RS83 in combination with the return belt RB75 and is the perfect option for the track-mounted R900 impact crusher to ensure 100% defined final grain.

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

Transport dimensions & Weight R900+RS83+RB75

  • Length: 14,10 m / 46.3 ft
  • Width:    2,50 m /   8.2 ft
  • Height:   3,25 m / 10.7 ft
  • Weight: 28,60 t /  63,100 lbs

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.
