A brief introduction to hammer crusher

The hammer crusher is a crusher that crushes materials with a particle size of 600-1800 mm to 25 or below 25 mm. It is suitable for medium and fine crushing of medium-hard and brittle materials.

Application field

Sand factory, quarry, expressway, high-speed railway, high-rise buildings, municipal engineering, hydroelectric dam construction, concrete mixing plant, metallurgical plant, etc.

Advantages of hammer crusher

1 With high productivity and large crushing ratio (generally 10-25, even to 50), it is often used in large-scale and high-yield production lines.

2 It can reduce the cost by about 40% by one-time moulding without secondary crushing and shaping process.

3 The discharging particle size is small, uniform and cubic with less over crushing.

4 Simple structure, compact size, low dead weight and low power consumption per unit product.

5 Continuous reliable work, easy maintenance and repair. The vulnerable parts can be easily repaired and replaced.

6 The discharge port can be adjusted, so the particle size can be adjusted according to customer requirements.

The structure of the hammer crusher

The hammer mill rock crusher is mainly composed of the frame, rotor, main shaft, hammerhead and other components.


The frame of the hammer crusher

The inner wall of hammer stone crusher is inlaid with impact and wear-resistant steel lining plates.

Bearing supports are installed on the left and right-side walls for placing bearings and supporting the rotor. The base of the frame is connected to the concrete with anchor bolts.

To prevent foreign matter from entering the bearing, a shaft seal is installed where the frame contacts the shaft.


The rotor of the hammer crusher

The rotor is the main working part of the hammer mill crusher.

The motor drives the rotor directly through the elastic coupling.

Then the material is broken due to the impact of the hammer on the crushing plate caused by the rotor rotation.

Main shaft

The main shaft of Fote hammer crusher

The main shaft is the part of the hammer crusher supporting the rotor.

The mass of the rotor and hammer head, as well as the impact force and torque generated during rotation, are borne by the main shaft.

Hammer head

The main wearing part of the hammer crusher hammer head

The hammer head is the main wearing part of the hammer crusher. The choice of hammer head affects the efficiency of the hammer crusher.

The choice of the hammer head

Types of hammer head Features Disadvantages
High manganese steel hammer head Good toughness and wear resistance, low price, wide application. If the impact force is insufficient or the contact stress is small, its wear resistance cannot be exerted.
Low alloy steel hammer head Less wear and tear, longer service life than high manganese steel. Complicated technology
High-chromium iron hammer head + high manganese steel or carbon steel hammer handle Good wear resistance of hammer head and high toughness of hammer handle. Complicated technology

How does the hammer crusher work?

When the material enters the hammer mill crusher machine, it is immediately impacted, ground and crushed by the high-speed rotating hammer.

Obtaining kinetic energy from the hammer head, the crushed material impacts on the liner of the inner wall at a high speed to be crushed a second time.

After that, the materials smaller than the size of the screen hole are discharged through the gap, while materials of larger size are left on the screen plate to continue to be crushed and ground by a hammer, and finally discharged through the screen plate.

In the whole process of material crushing, the materials also impact and crush each other.

The types and differences of hammer crusher

The hammer mill crusher is mainly PC series. With the development of the industry, the hammer crusher is constantly being improved. The heavy hammer crusher is its upgraded version, and the PCZ is the main series.

In terms of applicability and principle, there is almost no difference between them, except the difference is in the configuration position of the production line and the performance of the hammer.

Different positions in the production line

The feed inlet of the heavy hammer crusher is larger than that of the hammer crusher, which also determines their position in the crushing production line.

The heavy hammer crusher is used for coarse crushing of ore, that is, the primary crushing process. The hammer crusher in the projects, especially large-scale crushing production lines, is often used together with heavy hammer crushers for medium or fine crushing.

Different hammer performances

The hammer head of the heavy hammer crusher is heavier than that of hammer crusher, generally higher than 20kg, so the crushing force of the material is greater, and the material that can be crushed per unit time is significantly higher than that of the general hammer crusher.

What are the factors that affect the output of hammer crusher?

1 The hardness of the processed materials. The hardness of the crushed materials must be within the crushing range of the hammer stone crusher.

2 The humidity of processing raw materials. If the humidity of the raw materials is too high, there may be a bonding phenomenon when the hammer crusher works, and the particle size of the finished product will not be uniform.

3 System capability. The improper installation of the spare parts may result in insufficient production capacity of the whole system.

4 Feeding. The feeding should be uniform and the amount of feeding should be appropriate.

5 Hammer head of hammer crusher. The wear of hammer head not only affects the production capacity and output particle size of hammer crusher, but also accelerates the wear of equipment.

2 Cost-saving. The quartz stone crushing production line is mainly composed of two heavy hammer crushers and auxiliary equipment, which simplifies the process and saves later installation costs and maintenance costs.

3 High quality of finished products. Equipped with the heavy hammer crusher, the finished product has good grain shape with fewer edges and low powder content, realizing precise processing of quartz stone.

Fote engineers remind — There are several points to be noted when using the heavy hammer stone crusher:

Fote heavy hammer crusher working on site

Fote heavy hammer rock crusher working on site

  1. 1 Heavy hammer crusher, the same as other crushing equipment, should be equipped with iron removal equipment to ensure safe operation of the equipment.
  2. 2 The water content of the feeding material should be controlled below 12% to avoid blockage.
  3. 3 During the replacement of toothed and smooth hammer heads, each piece should be weighed. The total weight error of the two groups of symmetrical hammer heads should be controlled within 0.1kg.
  4. 4 Frequently check the wear of the hammer head and adjust the adjustment mechanism in time.
