impact crusher for fine crushing of rocks and other minerals

The impact crusher crushes out the material with uniform particles, excellent particle shape and high output, which is widely used in sand and gravel quarry, mining, coal mining, concrete mixing plant, power plant desulfurization and many other industries.

Impact crusher features:

1. multi-cavity uniform crushing: impact crusher adopts multi-cavity crushing design, which can make the material in multiple crushing cavity for uniform impact, crushing effect is good, the material crushing is more uniform.
2. cubic shape: the crushed product size is uniform, cubic shape, to avoid the generation of needle and flake materials, and the crushed material is almost no internal cracks, suitable for high-grade highways, airports, construction and other industries.
3. large feed opening design: low profile large feed opening makes feeding more convenient, can adapt to larger feed size, suitable for large production lines.
4. wear-resistant materials: the use of new wear-resistant materials manufactured plate hammer, impact plate and liner, with a longer service life, reducing equipment maintenance costs.
5. high efficiency: impact crusher can not only carry out high efficient crushing operation, but also can carry out material shaping, improve the shape of the material particles, to meet the higher standard of production needs.

The working principle of impact crusher:

The high-speed rotor is used to drive the plate hammer, the material enters the crushing chamber and has a strong impact with the plate hammer, the plate hammer breaks the material, and then it is bounced back by the counterattack device (usually counterattack liner) and continues to collide with the plate hammer. This process continues to repeat, the material is continuously crushed from large to small.

1. rotor rotation: the motor drives the rotor to rotate at a high speed, the material is sent into the crushing chamber, and enters the plate hammer action area.
2. Impact Crushing: The material is crushed by the impact of the hammers on the rotor and thrown to the impact liner for crushing again.
3. Repeated cycle: the material is repeatedly hit and rebounded in the crushing chamber, and after reaching the required size, it will be discharged from the discharge port.
4. Gap adjustment: the gap between the impact frame and rotor can be adjusted to change the granularity of the crushed material to meet different production requirements.

Application areas of impact crusher:

1. sand and gravel quarry: produce high quality construction sand and gravel, suitable for all kinds of construction projects.
2. Mining: used for the medium crushing of ores and rocks, especially suitable for the crushing of ores with large hardness.
3. Coal Mining: Processing lump coal in coal mines, crushing large coal mines into fine-grained coal dust.
4. Concrete mixing plant: It can be used to crush concrete blocks, construction waste, etc., providing raw materials for concrete mixing.
5. Dry mortar industry: processing limestone and other raw materials to produce dry mortar.
6. power plant desulfurization: crushing limestone and other raw materials, desulfurization operations, reduce environmental pollution.
7. quartz sand production: processing quartz stone, river pebbles and other materials to produce high purity quartz sand.

Advantages of Impact Crusher:

1. excellent particle size: because the impact crusher can not only crush the material, but also can be shaped, so that the crushed material has excellent particle size and cubic shape, which meets the requirements of high standard construction sand.
2. high abrasion resistance: the plate hammer is made of high chromium cast iron, which has strong abrasion resistance and can withstand large impacts, prolonging the service life of the equipment.
3. low maintenance cost: the folding line design of the impact plate and liner plate makes their service life longer, and they can be interchanged according to the wear and tear situation, which further prolongs the service life of the equipment.
4. strong over-iron protection function: the counterattack frame adopts self-weighted suspension structure, when encountering iron or other foreign objects, the counterattack frame will be quickly lifted to protect the equipment from damage. After discharging the foreign matter, the impact frame will quickly return to its original position to ensure the normal operation of the equipment.
