PCH Hammer Crusher is a new type of crushing machinery. It can be crushed in dry and wet forms. In the building materials, metallurgy, chemical industry, and thermal power generation industries, it is mainly used to crush coal, coal gangue, sandstone, shale, limestone, gypsum and other minerals, and is also used to crush fiber structure, elastic and tough wood, paper or asbestos cement waste to recover asbestos fiber, etc. In addition, hammer crushers can not only be used in crushing production lines and sand making production lines, but also can replace cone crushers in mineral processing production lines.
 

The main body of the hammer crusher is mainly composed of the following parts: frame, rotor, grate, synchronous adjustment device, upper cover opening device and other parts. The rotor body is composed of rotor disc, pin shaft, and hammer ring.


 

The hammer crusher is a device that crushes materials by colliding with the materials through the high-speed rotating hammer. It has the characteristics of simple structure, large crushing ratio and high production efficiency. It is widely used in the crushing of various medium-hard and weakly abrasive materials. The compressive strength of the materials does not exceed 100MPa and the moisture content is less than 15%. The crushed materials are coal, salt, chalk, gypsum, alum, bricks and tiles, limestone, etc. Since the hammer crusher can produce a certain mixing and self-cleaning effect, it can crush feed, bones and prepare fish meal, etc. It can also be used to crush fiber structures, broken wood, paper and asbestos cement waste and other materials with certain toughness.
 

The hammer crusher is an impact rotor crusher with a hammer. The hammer can not only rotate with the rotor, but also rotate around the hammer pin. After the material enters the crusher, it is crushed by the impact of the high-speed rotating hammer in the crushing chamber. The crushed material also obtains kinetic energy from the hammer and rushes to the crushing plate at high speed, undergoes secondary crushing, and then falls onto the screen plate. Through the shearing, extrusion, grinding of the hammer and the collision of the materials, the material is further crushed and discharged from the machine through the screen hole. The debris that cannot be crushed is pushed into the metal collector by the hammer and removed regularly by the operator. The adjustment of the discharge particle size is achieved by replacing the screen plates of different specifications. The distance between the rotor and the screen plate can be adjusted by the adjustment mechanism as needed.

Main advantages:

1. The liner is made of high-quality wear-resistant material, which is wear-resistant and has a service life of 1.5-2 times that of ordinary liner;
 

2. The structure is simple, the liner is easy to replace, and it is convenient to shut down for maintenance, which saves a lot of time;
 

3. The product particle size is controllable and the particle shape is uniform. The gap between the screen bars can be changed by changing the screen bar style or embedding filling blocks at both ends of the screen bar frame slot;
 

4. The equipment is tightly sealed, which can achieve dust-free leakage, suitable working environment, and no large dust.
