Description

A Combined Crusher

technical field

The utility model relates to the field of crushing machinery, in particular to a combined crusher.

Background technique

Crusher is a kind of material crushing device, which is widely used in metallurgy, mining, chemical industry, cement and other industries. In many industries, there are a large amount of raw materials and reusable waste that need to be processed by crushers, which need to be crushed to the particle size required by the next step. According to the principle of crushing, crushers can be divided into impact crushers, hammer crushers, jaw crushers, roll crushers, compound crushers and so on. Among them, impact crusher and hammer crusher are two typical crushers.

The impact crusher can also be referred to as impact crusher for short. When the impact crusher crushes materials, driven by the motor, the inner rotor of the impact crusher rotates at a high speed to drive the blow bar on the rotor to rotate, and the material enters the impact crusher. When the inner blow bar is in the action area, it collides with the blow bar and is broken, and then is thrown to the impact device for re-crushing, and then bounces from the counter-attack liner back to the blow bar action area for re-breaking, and this process is repeated. The impact crusher has the characteristics of large feed particle size and large crushing ratio, so it is widely used, but its disadvantage is that the particle size of the product is uneven and uncontrollable.

Hammer crusher is another commonly used crusher. Hammer crusher is a crushing machine that uses the high-speed impact of the hammer head to perform medium and fine crushing operations on materials. The hammer head is hinged on the high-speed rotating rotor, and the lower part of the machine body is equipped with a sieve plate to control the discharge granularity. The hammer crusher has the characteristics of uniform particle size of the product, but the disadvantage of the hammer crusher is that the feeding particle size cannot be too large, and the material is easy to block, and the coarse material at the end of the sieve plate cannot be discharged in time; and when the product particle size needs to be obtained When it is relatively small, the output is relatively low.

To sum up, how to provide a combined crusher that can effectively combine the advantages of the above-mentioned different types of crushers, which can not only crush large-grained materials, have a large crushing ratio, and is not easy to be blocked, but also obtain a product with small particle size, uniform product particle size and high output. Crusher has become a problem to be solved urgently by those skilled in the art.
