Technical description:

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

- body
- rotor
- grate
- drive
- hydraulic installation

Crusher body - made of metal sheets, welded structure and consists of a lower and middle part and two covers. The upper part of the body together with the covers constitute the crushing chamber, which is lined with replaceable protective plates. The central part of the body is additionally divided into three parts to facilitate the disassembly of the rotor without the need to disassemble the hopper. In order to facilitate the disassembly of the protection plates and hammers, hydraulically opened covers were used. On the outside of the lower part of the body there are shelves for fixing the rotor. In the front and rear walls of the lower part of the body, there are doors for assembling and disassembling the grates. The hatches in the side walls in the upper part of the central body are used to control the wear of hammers and protective plates. Smaller hatches in the inserts are used to knock out the axes of the hammers.

Rotor - the rotor disks are mounted on the shaft via a keyway with spacers welded on one side. To clamp and fix the discs on the shaft, side nuts are used, which also constitute the rotor sealing rings in the body. The discs have axles on which the hammers are rotatably mounted. The entire rotor is mounted on rolling bearings embedded in steel bearing housings and supported on the shelves of the lower part of the body. The drive from the electric motor is transmitted to the shaft through the pulley of the V-belt transmission.

Grate - installed under the rotor. The grate consists of two symmetrical segments with replaceable grate bars. The material is finely shredded on the grate to the size of the set gap. The assembly and disassembly of the grate segments is carried out through the door in the front and rear walls of the body. The basis weight of the initial product depends on the slot, it is possible to supply the grate with a different slot, which would be more suitable for the fragmentation of a given material (separate order). The size of the gap in the grate influences both the size distribution of the starting product and the crusher performance. The grate is attached to the body side walls with eight M16 screws.

The crusher's drive - is an electric motor and a belt-wedge transmission. The engine is placed on a tension slide with the possibility of tightening belts. The belt-wedge transmission is protected by a cover. Hydraulic installation - the complete hydraulic system consists of: a hydraulic power pack, a two-section distributor, four hydraulic cylinders, hoses and pipes, tees, connection bodies and gaskets. The installed power is 1.1 kW. A hydraulic system has been used to facilitate the opening of the two covers.

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 belt 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 set grate gap takes place on the grate basket. The crushed material falls down by gravity onto the receiving conveyor.
