Crushers can be divided into medical crushers and mining crushers according to the major categories. Among them, the medical lithotripter is mainly used for breaking stones, and the stones are usually broken by resonance to avoid various risks caused by surgery.
According to the principle of crushing, the commonly used crushing machinery of heavy mining machinery is jaw crusher 32313133353236313431303231363533e78988e69d8331333431363563 crusher, impact crusher, vertical impact crusher, hydraulic cone crusher, ring hammer crusher, hammer crusher, roller crusher Machine, compound crusher, cone crusher, two-stage crusher, gyratory crusher, mobile crusher, etc.
The working principle of different types of crushers is also completely different. Take the ring hammer crusher as an example:
The hammer crusher mainly relies on impact energy to complete the crushing of materials. When the hammer crusher is working, the motor drives the rotor to rotate at high speed, and the material enters the crusher cavity evenly. The high-speed rotating hammer head impacts, shears and tears the material, causing the material to be crushed. At the same time, the gravity of the material makes the material from The high-speed rotating hammer head rushes towards the baffle and sieve strip in the frame. At the lower part of the rotor, there is a sieve plate. The particle size of the crushed material that is smaller than the size of the sieve hole is discharged through the sieve plate. Shang continued to be hit and ground by the hammer. .
In the industrial sectors of metallurgy, mining, chemical industry, cement, etc., a large amount of raw materials and recycled waste materials need to be processed with a crusher every year. For example, in a beneficiation plant, in order to achieve the separation of useful minerals in the ore, it is necessary to use a crusher to crush the original ore to the particle size required by the grinding process. It is necessary to use a crushing machine to crush the raw materials to the particle size required for the next operation. In the coking plant, sintering plant, ceramic plant, glass industry, powder metallurgy and other departments, the crushing machinery must be used to crush the raw materials to the particle size required for the next operation
