The MR 48-200 single-shaft grinder is suitable for processing large quantities of industrial waste. The heavy structure makes the machine suitable for heavy duty.
The pusher drawer is operated via a hydraulic power unit. The product to be ground is thus pushed towards a tool-holder rotor which causes it to be crushed. Thanks to a grid, the final dimensions of the ground can be selected.
