According to the principle of crushing, the commonly used crushing machinery for heavy mining machinery includes jaw crushers, impact crushers, vertical impact crushers, hydraulic cone crushers, ring hammer crushers, hammer crushers, roller crushers, composite crushers, cone crushers, two-stage crushers, rotary crushers, mobile crushers, etc.
The working principles of different models of crushers are also completely different. Taking 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 evenly enters the crusher chamber. The high-speed rotating hammer head impacts, cuts, and tears the material, causing it to be crushed. At the same time, the gravity of the material itself causes the material to rush from the high-speed rotating hammer head towards the baffle and screen strip inside the frame. At the lower part of the rotor, there is a screen plate, and particles smaller than the size of the sieve hole in the crushed material are discharged through the screen plate, Materials larger than the size of the sieve opening are retained on the sieve plate and continue to be hit and ground by a hammer.
