What is the appropriate moisture content of materials processed by impact crushers?

The traditional crusher with grate and screen plate is not suitable for materials with a high moisture content. However, when the moisture content of the raw material is high, it is easy to be seriously clogged, making the hammer head unable to rotate, the material unable to be discharged, or even burning out the motor, seriously affecting production. The design of this machine does not have a screen grate bottom and does not have strict requirements on the moisture content of the material. There is no problem of the screen plate being blocked by paste, and there is no recurring problem of fine powder not being discharged in time. Therefore, the crushing efficiency is high and there is no ineffective wear of the hammer head. At present, coal gangue and cinder are used as additive fuel in brick factories. Using coal gangue shale to produce standard brick hollow bricks is a major measure in line with national policies and benefiting society. However, the problem of crushing these materials, especially the crushing of wet materials, has always been a problem that plagues the normal production of brick factories. After long-term investigation, careful design and bold practice, our company has successfully developed and produced a utility model patent that can easily crush high-humidity coal gangue, shale, cinder and other materials. The newly launched two-stage crusher is equivalent to two hammer crushers. The two sets of rotors are combined into one and reasonably form a whole. The use of two sets of rotors in series has the following outstanding advantages. The two sets of rotors connected in series with each other for upper and lower stages of crushing allow the materials crushed by the upper rotor to be finely crushed again by the hammer head of the rapidly rotating lower rotor. The materials in the inner cavity collide with each other rapidly and crush each other to achieve the dual effect of the hammer crushing the materials.
