Product Description

Introduction of Hammer Mill

Hammer mill is engaging in crushing various rocks and stones with comprehensive strength not higher than 320 MPa into coarse powder and small particles, it is widely used in metallurgy, mining, chemical, cement, coal, sand-making, coal gangue, construction, refractory materials and ceramic industries.

Finished size: 0-22mm

Capacity: 3-45t/h

Application: widely used in metallurgy, mining, chemical, cement, coal, sand-making, coal gangue, construction, refractory materials and ceramic industries.

Raw materials: Glass,Limestone, calcite, barite, etc

Working principle of Hammer Mill

Hammer Mill mainly consists of frame, rotor, support iron and grate bars. The frame is divides into two parts: upper part and low part, which are welded by steel plates after being cut. Liners made of high manganese steels within the frame can be replaced after being worn out. The rotors consist of turnplates, pin shafts, and hammers which are grouped regularly in the main shaft. The main unit drives the main shaft through the motor and triangle belts, which, in turn, rotates the rollers. Large materials entering the crusher through the feed inlet are firstly crushed by the high-speed hammers, and the thrown fiercely to the support iron for further crushing. Qualified materials crushed will be screened out and exit from the gap of the grate bars while the unqualified will be left in the crushing cavity to be further hammered and ground until reach the standard size. The size of the final product can be adjusted by changing the grate bars. The gap between the rotors and the grate bars can also be adjusted according to different requirement. To avoid the plugging of the crusher, the proportion of water for the crushing material is no more than 20%.

Advantages of Hammer Mill

1. Uniform particle size with high crushing and crushing ratio;

2. High capacity and low power consumption;

3. Simple structure; Easy operation; 

4. Low investment and environmantal-friendly.
