Hammer Crusher is widely used in mining, metallurgy, building materials and other industries to crush various brittle materials, such as coal, gypsum, limestone, etc. Improving the working efficiency of hammer crusher and optimizing the work process are the key to ensuring production benefits.
Methods to improve work efficiency:
1. Optimize feed size:
Reduce the feed size of materials: If the particle size of the raw material is too large, the crusher load will increase and the crushing efficiency will be low. By adjusting the front-stage crushing equipment or screening equipment, controlling the feed size to make it suitable for the working requirements of the hammer crusher, the crushing efficiency can be improved.
2. Reasonable selection of hammer material and structure:
Using high wear-resistant materials (such as high chromium cast iron or alloy steel) to manufacture hammers can effectively extend the service life of the hammers, reduce downtime, and ensure continuous and stable production.
Adopt a more suitable hammer structure, such as single-sided or double-sided hammers, and select the appropriate number and shape of hammers according to the characteristics of the material to optimize the crushing effect.
3. Reasonable control of speed:
The speed of the hammer crusher directly affects the crushing effect and output. Too high a speed may easily cause too much fine material; too low a speed may lead to low crushing efficiency. The appropriate speed should be selected according to the nature of the material, usually 800-1500 revolutions per minute.
4. Reduce material blockage:
Configuring a reasonable screen aperture or avoiding too wet or too hard materials from entering the crusher can reduce material blockage and ensure continuous production.
5. Regular maintenance and care:
Regularly check the various parts of the hammer crusher, replace worn parts in time, and keep the equipment in good working condition.
Clean up the dust and foreign matter in the equipment, and keep the fan and discharge port unobstructed.
6. Increase the effective space of the crushing chamber:
Increase the effective space of the crushing chamber so that the hammer head can fully play its role and increase the amount of crushed materials.
Working process of hammer crusher:
1. Material feeding:
The material is fed into the feed port of the hammer crusher through the feeder. The material is evenly fed into the crusher through a vibrating feeder or a belt conveyor.
2. Crushing process:
After the material enters the crushing chamber, it is crushed into small particles by the impact and shear force of the high-speed rotating hammer. The hammer continuously hits the material during the rotation process, and the interaction between the hammer and the liner causes the material to be crushed.
3. Material screening:
The crushed material is screened through a screen or a grid screen. The size of the screen hole can be adjusted according to demand. Qualified materials are discharged from the bottom, and oversized particles continue to be crushed in the crushing chamber.
4. Discharge:
The crushed material is discharged through the discharge port and is usually transported to downstream equipment by a belt conveyor.
5. Circular crushing:
If some materials are still too large, they will re-enter the crushing chamber for secondary crushing until the material reaches the required particle size.
By reasonably controlling each link and optimizing the performance and use of the equipment, the working efficiency and production capacity of the hammer crusher can be greatly improved.
