Jaw crusher use two jaw surface to extrude and bend the material, then crushing or breaking the various hardness materials. It is composed of fixed jaw and moving jaw, when two jaw is close to the material, the material will be broken. When two jaw leave, less than the material of discharging mouth piece discharges from the bottom. The movement of crushing is intermittent. The crusher has the characteristics of simple structure, reliable operation and crushing hard materials. So it is widely used in mineral processing, building materials, silicate and ceramic industries.The different condition workplaces: in the production, the impact crusher can use in the different environment, this will have different influence on the impact crusher and affects the impact time.the speed of impact: changing the speed of impact and keeping other things being not change, we start to analysis the impact time under different impact speed. At last, we can find that the impact time will change along with the increasing of impact speed, but the range of changing is not big. The lower speed will have a small result. Guarantee the feed source: In mineral processing, the first is the blasting operation, after the blasting operation, the products will be raw material for crushing. Its quality is directly related to the service life of crusher and efficiency. But we need to deal with the large pieces of stone secondly so that meet the needs of production. If the large rock gets into the crusher, crusher will be jammed, you must stop. So the large piece of stone affects the life of crusher. We should do something in the first process, improving the parameters of blasting operation, reducing particle size of stone after blasting.Hongxing Brand is the China Famous Brand, and Hongxing believes that reliable and stable quality is the key to success.
