The DG series roll crushers are designed for crushing the brittle and medium hard materials.
The roll crusher is a housing with the guides installed on it. The bearing units where the shafts with the rolls secured are installed move by guides. . One of the rolls is pressed by the spring units that prevent the crusher from breakage in case of uncrushable objects ingress. The spring compressive force provides for the required crushing force. The position of the second roll is provided by the jaw adjustment units.
The crushing area is covered by the dust-protection casing with the feed hopper therein. The housing encloses the motors arranged on the junction platforms. The motors can be accessed through the hatched windows in the sides walls of the housing. The motors are controlled by magnetic starter arranged inside the housing and by buttons on the side wall of the housing.
Operating principle
The feed material is loaded into the hopper and flows to the crushing area where it is broken between the rotating rolls. The crushed product flows from the crusher by gravity through the inlet chute of the housing.
