Versatile and robust – Material pre-breaking for soil washing

To pre-break material for soil washing, this double roll crusher of type Sizer 550-13 is used in Switzerland’s most advanced soil washing plant. It needs to be versatile and robust because it processes mineral construction waste of all kinds with compressive strengths up to 300MPa. Material ranging from 0-500mm is crushed to a final grain size of 99% <80mm. The mechanical synchronization of the roller operation, originating from our company, is primarily responsible for maintaining the specified maximum grain size. Throughputs of 80t/h are achieved. Theoretically, it still has plenty of room for improvement.
