TECHNICAL DESCRIPTION:

General description of the structure:

The basic elements of the crusher are the body, fixed and sliding rollers and the roll housing. The shafts are mounted on spherical roller bearings in housings and secured with a toothed washer, a bearing nut, covers, labyrinth rings and a pressure washer. Fixed shaft bearing housings are set on the body and the movable roller on a sliding slide. The shafts are driven by two geared motors which rotate the shafts with rollers in the opposite direction. Rollers with shafts and geared motors are secured against rotation by reaction arms and against overload by a level-spring system (disc springs).

A description of the action:

The raw material passes between the rolls through the housing inlet. The crusher has the ability to adjust the gap between the rollers in the range of 2-10 mm through a package of adjustment shims. To adjust the gap, move the sledge with the roller away from the thrust beam with two bolts and insert the appropriate number of adjustment washers between the beam and the sledge. After determining the correct gap, unscrew the above bolts and tighten the carriage to the thrust beam with the middle bolt. During crushing, temporary overloads may occur due to materials much harder than the crushed raw material getting between the crusher rolls. For this purpose, a lever-spring was used.
