What is crusher？According to the large class，crusher can be divided into medical and mining gravel machine.Mining crusher is adapted in large mine hard rock broken, its typical granite, the material particle size less than or equal to 40 mm accounted for 90%, the function deal with side length of 100 ~ 500 mm in the following materials, the maximum compressive strength of 350 MPa. It has the following advantages: broken ratio is large, broken material is cubic particles etc..Mining gravel machinery is refers to the crushing machinery that grain size is greater than three mm in the aggregate content of the total discharge amount of more than 50% .
What is crusher？According to the principles of broken, heavy mining machinery used crusher are jaw crusher, counterattack type crusher, vertical impact crusher, hydraulic cone crusher, type ring hammer crusher, hammer crusher, roller crusher, composite type crusher, cone crusher, the two-stage crusher, gyratory crusher, mobile crusher, etc..
What is crusher？The working principle of different types of crusher is completely different.Taking the ring hammer crusher as an example:
Hammer crusher is mainly rely on impact energy to complete the operation of the broken material. Hammer type crusher is working, the motor drives the rotor to rotate at a high speed, material evenly into the crushing chamber, high-speed rotary hammer impact and shearing tear material caused by the material being broken. At the same time, the material of its own gravity materials from the high-speed rotating hammer rushed to the frame body plate, screen, the lower part of the rotor, with sieve plate, crushing the material less than sieve size fractions discharged through the sieve plate, greater than the pore size of material resistance at sieve plate continue to be a hammer blow and grinding.
What is crusher？Although the impact crusher appeared late, but the development of fast. It has been our country cement, building materials, coal and chemical and mineral industries are widely used in all kinds of ores and finely homework. He did do ore crushing equipment. The rapid development of the impact crusher is mainly because it has the important characteristics of the following.
What is crusher？Now,you should know about it.
