Impact crusher is a relatively new high-efficiency crusher. Impact crusher with a crushing ratio, adaptability, simple structure, small size, easy operation, easy maintenance. Impact crusher types are more common now a counter-attack crusher and hammer crusher. Impact crusher are the specifications of the rotor diameter D (refer to the trajectory of the hammer tip diameter) and length L expressed in millimeters. For example φ1000 x 800 single-rotor hammer crusher, φ1250 x 1000 single rotor impact crusher.

Impact Crusher Application

Impact crusher in chemical, cement and other industries widely used crushing medium hardness materials. Impact crusher is the use of knock-on effects for the broken, it is particularly suitable for medium to pieces of broken material, such as silica, sintered dolomite, clay, clinker, liSBMne and other materials and sintered magnesia.

Impact crusher works

Impact crusher works by using high-speed rotation of the hammer impact materials, so along the cleavage plane, bedding plane, and natural cracks and other vulnerable segments of the broken. To the material into the crusher, to be around the central axis to 25 ~ 40 m / s high-speed rotation of the rotor speed after a violent collision, by first crushing; and materials obtained from the rotor speed can fly hard disk drive wall by the first secondary crusher; shot in the back of the material impact of the process was again crushed the rotor is difficult to break the material, is held hostage by the rotor and the fixed plate and cut, broken product discharged from the lower part. When asked crushing product size is 40mm, sufficient to achieve the purpose, and if required more than 20mm size, the next need a hammer and grinding by the board, and further refine the material, during which the gap is much smaller than the impact of board and the gap between the hammer, if the bottom of the screen and then with grate, can more effectively control the discharge size. The impact of the distance between the plate and hammer, impact plate and tilt can be adjusted. Rational arrangement of the impact plate, so that broken things exist in the broken loop, until it fully broken, and through the gap between hammer and plate or grate sieve sieve, from the plane.

Impact crusher features

Crushing ratio. Impact crusher broken than the average of 30 to 40, up to 150 or more. Which can be completed in time, fine or coarse, medium, fine, reduce the number of broken segments, simplifying the production process.
Uniform particle size, too small crush phenomenon. Impact crusher is the use of kinetic broken materials, each material has the kinetic energy of the block size of 41 is proportional to the quality of materials, so in the crushing process, the bulk material by a greater degree of fragmentation, small granular materials , under certain conditions, not to be broken.
Crushing, high efficiency, low power consumption. Impact strength of materials is far less than the compressive strength, the material under high-speed, multiple attacks, along cleavage boundaries and vulnerable parts of the organization was shot and crack, so the impact crusher with high efficiency. Energy consumption, production large capacity. Particle size and mostly broken cube, which is to improve the bulk density of refractory products is beneficial.
Adaptability. Brittle and can break the following materials in hard, especially suitable for crushing brittle materials such as coal, liSBMne, silica, etc.
Device structure is simple, light weight.
