The new Rubble Master RM80 compact crusher can handle material with a maximum feed size of 700mm at a rate of 150 tonnes/h.
"Designed to handle rock, building rubble, asphalt and concrete, the 22-tonne machine produces material ranging from 0–30mm to 0–70mm. In the event of the crusher becoming blocked, an integrated release system frees it within seconds. Hammers can be changed in around 10min per hammer and all maintenance points can be reached from ground level."
"The all-new RM80 features a low loading edge, making it easy to load material, while the high discharge level allows high piling. The integrated two-step pre-screen with an adjustable hole size of 30–80mm improves the quality of the end product and reduces machine wear."
The unit can be changed from a secondary to a primary crusher in 40min. Through- put is automatically set by the machine according to feed material and feeding equipment. Conveying is adjusted automatically ac-cording to crusher load.
"The RM80 is available with a hook-lift system, making it ‘container mobile’. With hydraulic legs it can be transported on a low-bed truck and with crawler gear on a low-bed trailer."
