Impact Rock Crusher

What is an impact rock crusher machine?

An impact rock crusher is used to crush various rock materials for size reduction with high hardness such as concrete and limestone. It enjoys the features with large crushing ratio, no tension and cracks, durable wearing parts and large output. The most important thing is that the size of the discharge can be adjusted and the crushing specifications of the impact rock crusher are diversified.

Under normal circumstances, the impact rock crushers are made of high wear-resistant materials and the best crushing chamber, being of excellent performance, which is very suitable for crushing all kinds of soft, medium hard ore, coarse materials. The impact rock crusher is also applied in refractory materials and ceramics, aggregates recycling, road construction, water conservancy projects, building stone works and so on.

The impact rock crusher can be used both in primary and secondary stone crushing process for maximizing throughput of raw materials, and pre-screening is available to maximize productivity.

How many types of impact rock crusher are there in Hongxing Machinery?

Hongxing impact rock machines includes the normal version of impact rock crusher, VSI vertical shaft impact crusher, HD German version and HX , CI series and other types. The CI series impact rock crusher machine is a new type of ones,  which adopts excellent impact rock crusher technology at home and abroad. For different applications, the rotor and crushing chamber type refining equipment, a large number of new high wear-resistant materials are used, and the equipment performance and processing capacity are greatly improved. The HX series is the best choice for industries such as building aggregates and construction waste recycling.

What is the impact rock crusher process flow diagram?

-The impact Rock crusher equipment process

The impact rock crusher machine designed by Hongxing Machinery can be made up into the whole crushing production line which composed of vibrating feeder, jaw crusher, impact crusher, vibrating screen, etc. It is able to process large production materials, like the 4043t and 5256t impact crushers.

-The impact rock crusher working principle

When the power of impact rock crusher is turned on, the rotor in the crusher is driven by the motor to start high-speed rotation. The aggregates will be thrown from the high speed into the cavity of impact rock crusher, and the rotor is violently impacted, then the materials will be impacted by the rotor. It is thrown toward the counterattack along the tangential direction of the rotation of the rotor, after that, it bounces back from the counter plate to the space of rotation of the rotor to receive the second impact, and then throws it to the second counterattack.

After the materials are subjected to the repeated impact and rebound of the rotor and the counterattack plate, cracks will be generated along the self-joining joint surface, and the internal structure will be loosened and broken by the impact. The materials that meet the crushing specifications will be discharged outside the reserved gap which is between the rotor and the counterattack plate.

-Impact crusher settings

An impact rock crusher can adjust the discharging granularity in a variety of ways, such as adjusting the rotor speed, adjusting the clearance between the counterattack and the plate hammer (top bolt adjustment device), etc.

The European version of the impact rock crusher can adjust the distance between the third counterattack and the plate hammer. through adding or reducing gaskets in the lower part.

Adjusting the gap between the counter frame and the rotor frame can achieve the purpose of changing the particle size and shape of the material. The first and second counter-attacks pass through the top screw adjustment device, and if there is a third counter-attack plate (European version counter-break), the gasket is adjusted.

-Water content requirement of impact rock crusher machine

The feed chute of the impact rock machine and the counter-attack plate can be equipped with a heating device to prevent the materials from being bonded, thus the materials with a large water content can be broken, thus the clogging phenomenon is less likely to occur.

Impact rock crusher machine has refinement design of the rotor and cavity type, speed and power are reasonably matched to meet the different application options of coarse crushing, medium fine crushing and material recovery. The solid heavy-duty rotor structure improves the processing capacity and crushing ratio of the machine; the high-quality welded structure ensures the crusher machine can withstand the huge impact and get a good crushing effect.

Impact rock crusher is also known for its ship-type hammer, reliable locking structure, good impact strength and wear resistance and stable discharge size. Besides, the new high-abrasion materials just as brittle rocks, limestones, cobblestones, gold mine, copper, etc., are used in large quantities to reduce the wear of wear parts, extend the replacement cycle, and save costs.

The impact stone crusher is equipped with a variety of case locking devices to improve safety performance while reducing labor intensity; optional third counter-attack frame to make the product grain shape more excellent.

-The wearing parts of impact rock crusher

The wear part problem of the hammer often refers to crushing the materials, and its metal utilization rate can be as high as 45% - 48%. When crushing limestone, the impact rock hammer is not seriously worn.
