TECHNICAL DESCRIPTION:

General description of the structure:

The following basic groups can be distinguished in the construction of the crusher:

- body
- rotor
- grate
- drive

Crusher body - made of metal sheets, welded structure and consists of a lower and upper part. The upper part of the body, which is also the crushing chamber, is lined with replaceable protective plates. On the outside of the lower part of the body there are brackets for fixing the rotor. Inside, brackets for the grate are welded in. There are doors for assembly and disassembly of the grate baskets in the front and rear wall of the lower body part.

Rotor - rotor disks with spacers welded on one side are mounted on the keyway on the shaft. The side nuts are used to clamp the discs on the shaft, which also constitute the rotor's sealing rings in the body. The discs have axles on which the hammers are rotatably mounted. The entire rotor is mounted on rolling bearings seated in divided housings and supported on consoles in the lower part of the body.

Grate - the grate is built under the rotor and consists of 2 symmetrical segments with replaceable sieves. The material is finely shredded on the grate. The assembly and disassembly of the grate segments is carried out through the door in the front and rear wall of the body. 

Drive- crusher drive is carried out by a drive motor through a belt-V-transmission.

A description of the action:

The torque from the electric motor is transmitted through the V-belt transmission to the V-belt pulley mounted on the rotor shaft, which causes the rotor to rotate. The material is fed by a conveyor to the crusher's charge. From the hopper, the material falls by gravity onto the rotating rotor and is initially smashed with hammers in the crushing chamber as a result of hitting armor plates. The final crushing of the lumps larger than the screen gap takes place on the grate basket. The crushed material falls down by gravity onto the receiving conveyor.
