The crushing principle of the crusher

The crushing principle of the crusher

Today I brought the working principle of the crusher, the hammer crusher, so that everyone has a more detailed understanding of the crusher. The impact crusher mainly relies on impact energy to complete the work of crushing materials. When the impact crusher is working, the motor drives the rotor to rotate at a high speed, and the materials evenly enter the crusher cavity.

The high-speed rotating hammer hits, cuts, and tears the material to break the material. At the same time, the gravity of the material makes the material rush from the high-speed rotating hammer to the inner baffle and the net of the frame. Below the rotor, there is a screen plate, and particles smaller than the size of the sieve hole are discharged through the sieve plate at the stage of being pressed, and the material larger than the sieve hole size will be blocked on the sieve plate, and continue to be impacted by the hammer and the ground until they are pressed to the The required discharge particle size and the last discharged machine pass through the screen. The motor of the jaw crusher drives the belt and pulley to move the movable jaw up and down through the eccentric shaft. When the movable jaw rises, the angle between the toggle and the movable jaw increases, thereby pushing the movable jaw closer to the fixed jaw. At the same time, the material is crushed, rubbed and ground; when the moving jaw moves downward, the angle between the toggle plate and the moving jaw becomes smaller. The movable jaw leaves the fixed jaw under the action of the pull rod and the spring.

At this time, the crushed materials are discharged from the lower opening of the jaw crusher's crushing cavity. With the continuous rotation of the motor, the motor jaw crusher is used for periodic crushing and discharging, realizing mass production. According to the crushing principle, the commonly used crushing equipment in heavy mining machinery includes jaw crusher, impact crusher, vertical impact crusher, hydraulic cone crusher, hammer crusher, reverse roller crusher, compound crusher, cone crusher , Two-stage crusher, impact crusher, mobile crusher, etc.
