The hammer crusher also named hammer mill, and crushes materials by the collision between the high-speed hammer and materials. Hammer crusher possesses qualities of simple structure, large reduction ratio, and high-efficiency.
The hammer crusher is used to crush mid-hardness and weak corrosive materials, whose compressive strength is under 100 Mpa, and water ratio is less than 15%. Hammer crusher possesses qualities of simple structure, large reduction ratio, and high-efficiency. Both Dry and Wet Process are available. Hammer crusher is used in mine, cement, coal, building material, metallurgy, chemical industry, road construction, gas chemical industry and thermal power generation, etc.
Hammer Crusher Operating Principle
Driven by the motor, the rotor of hammer crusher which consists of main shaft, disk, pin shaft and hammers rotates at high speed in the crushing cavity. Raw materials enter the cavity through the feed opening. Materials in the cavity are blown, impacted and ground by the hammer. Below the rotor is the sieve plate, which screens the materials.
Materials in the hammer crusher that reach the required size can be discharged from the sieve plate, while the oversize materials will be left and crushed again until reach the standard size. The final product size of the hammer crusher can be adjusted by changing the screening plate. The gap between the rotors and the screening plate can also be adjusted according to different requirement
Hammer Crusher Features
1. Simple structure and high reliability.
2. High crushing ratio and flexible capacity.
3. High efficiency and over-loading protection.
4. Suitable for dry and wet crushing.
Hammer Crusher Operation and Maintenance
The hammer crusher is a high-speed rotation of crusher equipment. In order to ensure its normal work, the operator must strictly follow the rules and regulations. Do the best work of operation and maintenance of hammer crusher equipment.
1. Check the hammer crusher before starting the machine. Make connect with the upper and lower processes, then star the crusher machine following the rules.
2. To empty start, attention: should be unload materials inside the empty cavity and then shut down
3. Regularly check the hammer, lining to see whether they are wore out. Once appear the above situation, resolve them immediately.
4. To maintain uniform feed so as not to metal debris into the hammer crusher
