Technical description:

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

- body
- rotor
- grate
- drive
- hydraulic installation
- crusher frame
- support frame

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 having to disassemble the hopper. In order to facilitate the disassembly of the protection plates and hammers, two hydraulically opened covers are used.

On the outside of the lower part of the body there are shelves for fixing the rotor. The hatches in the side walls located in the upper part of the central body are used to control the wear of hammers and protective plates.

Rotor - the rotor disks are mounted on the shaft via a keyway with spacers welded on one side. The side nuts are used to clamp and fix the discs on the shaft, 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 transferred to the rotor shaft directly through the claw clutch.

To prevent the hammer axes from slipping out, the hammer axes are secured. These protections are welded to one extreme disc of the rotor. In order to dismantle the axles, grind off the protections.

Grate - installed under the rotor. The grate consists of a support structure (sieve base) of a slotted sieve and two sheets pressing the sieve. The material is finely shredded on the grate to the size of the set gap. Assembly and disassembly of the grate is carried out through the door in the side wall of the lower body.

The basis weight of the starting product depends on the slot, it is possible to supply a slotted sieve with a different slot (separate order). The size of the gap in the grate influences both the size distribution of the starting product and the crusher's performance. The grate is attached to the body walls on three sides with M16 bolts.

The drive - crusher is an electric motor. The motor is centrally located on the crushing rotor axis, and the torque is transmitted via the QF100 claw clutch.

Hydraulic installation: The complete hydraulic system consists of: a hydraulic power pack, a two-section distributor, two hydraulic cylinders, hoses and pipes, connection bodies and gaskets. The installed power is 0.55 kW.

A hydraulic system has been used to facilitate the opening of the two covers.

The torque from the electric motor is transmitted to the rotor via a dog clutch, which causes the rotor to rotate. The material is fed to the crusher's charge. From the hopper, the material falls by gravity onto the rotating rotor and is initially crushed with working elements (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.
