The hammer crusher is a machine that crushes materials in the form of impact, in both single and double rotor form. It is a crusher for direct crushing of materials with a maximum size of 600-1800 mm to a section of 25 or less. The hammer crusher is suitable for crushing medium hardness materials such as limestone, slag, coke, coal, etc. in cement, chemical, electric power, metallurgy and other industrial sectors in medium and fine crushing operations.
The hammer crusher is divided into two forms: single rotor and double rotor. The single rotor is divided into reversible and irreversible types. Single rotor hammer crushers and ring hammer crushers are widely used.
It consists of hammer crusher box, rotor, hammer head, impact liner, screen plate, etc.
The main working part of the hammer crusher is the rotor with hammers (also called hammer head). It is crushed by the blow, impact, shear and grinding action of the hammer in high speed movement. Moreover, the rotor is equipped with a sieve plate in the lower part of the rotor, and those particles smaller than the size of the sieve are discharged through the sieve plate. It is suitable for crushing minerals of various brittle materials. The crushed materials are coal, salt, baiya, gypsum, alum, brick, tile, limestone, etc. The compressive strength of the hammer crusher material is not more than 100 MPa and the humidity is not more than 15%. It can be used as crushing equipment for stone crushing, stone crushing, mining crushing, plastic crushing, garbage crushing and other materials.
The main technical parameters are useful for comparison of different models of roughly the same category. These parameters for the PC300x200, PC400x300, PC600x400, PC800x600, PC1000x800 and PC1000x1000 models are as follows:
| Model | Feed particle size | Discharge particle size | Productivity | Number of motor poles | Power | Dimensions | Machine weight |
| mm | mm | t/h | kw | mm | kg | ||
| PC300x200 | 100 | 8 | 1-5 | 4 | 5.5 | 630*380*630 | 200 |
| PC400x300 | 200 | 25 | 5-10 | 4 | 11 | 900*670*860 | 800 |
| PC600x400 | 250 | 30 | 10-22 | 4 | 11-22 | 1200*1050*1200 | 1500 |
| PC800x600 | 250 | 35 | 18-40 | 4 | 30-55 | 1310*1180*1310 | 3200 |
| PC1000x800 | 350 | 35 | 25-50 | 4 | 75 | 1600*1390*1575 | 4300 |
| PC1000x1000 | 350 | 35 | 30-55 | 6 | 90 | 1800*1590*1775 | 8000 |
Hammer crusher is widely used in industrial sectors like cement, chemical, electric power and metallurgy, to crush materials with medium hardness, such as limestone, slag, coke, and coal. It has two forms-- single rotor and double rotor-- and is capable of reducing materials into small sizes with a maximum size of 600-1800 mm to 25 mm or less in one section.
Moreover, What makes it special is that it utilizes the impact crushing principle to crush materials, which makes it even more reliable and efficient. With its outstanding features, hammer crusher has become a mainstream crusher for crushing medium hardness materials and is widely used all over the world.
