PCM Diesel Hammer Crusher

PCM series is mainly used for crushing medium hardness and brittle materials, such as coal, cement, gypsum, alum, brick, tile, limestone and so on. The compressive strength of the material should not exceed 300 MPa, and the humidity should not exceed 15%. The equipment has the characteristics of simple structure, large crushing ratio, high production capacity and uniform particle size of the finished product. Different discharging granularity can be achieved according to customer requirements.

Raw Materials

widely used in coal, salt, chalk, gypsum, brick, limestone crushing process.


It is suitable for crushing medium hardness and brittle materials in mining, cement, coal, metallurgy, building materials, highway, combustion and other departments.

Hammer crusher is used for crushing all kinds of medium hard and weak abrasive materials. The compressive strength of the material is not more than 100MPa, and the moisture content is less than 15%. It is widely used in coal, salt, chalk, gypsum, brick, limestone crushing process.

Working Principle

The main working parts of PCM series hammer crusher are rotor with hammer head. The rotor consists of spindle, disc, pin shaft and hammer head. In the lower part of the rotor, there is a sieve plate. The motor drives the rotor to rotate at a high speed in the crushing chamber. The material from the upper inlet into the machine, crushed by the impact and grinding of high-speed movement of the hammer. The fine materials smaller than the mesh size are discharged through the sieve plate, and the coarse materials larger than the mesh size are prevented from being broken on the sieve plate, and then discharged through the sieve plate.

Features & Advantages

1. The ring-type hammer head of the hammer crusher is easy to install. When it is damaged and replaced, it only needs to turn on the cover to drop the edge of the hammer head. The workload of inspection and maintenance will less.

2. The ring-type hammer head automatically adjusts the position when working, the structure is stable, there is no dangerous section, the performance of preventing iron block is good, and the service life is greatly improved.

3. Change the sieve plate holes from round to long strip holes staggered to increase the strength of the sieve plate, the screen body is not easy to deform and crack after treatment, and the life of the sieve body is increased to 3-6 months.

4. The improved sieve plate can greatly reduce the frictional resistance of material filtering, and the feeding frequency can be adjusted according to the operation requirements, thereby increasing the output.

5. One end of the spindle is equipped with a flywheel to make the rotor store a certain kinetic energy in motion, which is used to reduce the peak load of the motor, reduce the wear of the hammer head, and make its operation more stable and reliable.

6. All wear-resistant parts are made of high quality wear-resistant materials at home and abroad, and a small number of wear-resistant parts are made of hard wear-resistant materials, which have a long service life and greatly reduce the cost of overhaul and maintenance.
