Extremely powerful mobile impact crusher in uncompromisingly robust design, ideally suited both for recycling and for the crushing of limestone. The crusher's 250 kW electrical drive, powered by a 365 kW diesel engine, makes short work even of heavily reinforced concrete or large blocks of limestone material. The large clearance between the rotor and the vibrating discharge chute, as well as the 1,400 mm wide discharge conveyor make sure that even twisted steel bars are moved into the magnet's contact area without difficulty. The machine's drive concept and intelligent design permit highly economically efficient operation.
