What is the reason for the blockage of the discharge port of the jaw crusher?

Although the discharge port of the jaw crusher is blocked, it is a minor fault, but it can affect the * of the crusher and affect the subsequent process of the entire production line. Once the jaw crusher is blocked during operation, the feeding must be s*ped immediately. After the jaw crusher is completely shut down, the blocked materials should be cleaned, the connection degree of each component should be checked, and the loose components should be re-fixed. So what are the main reasons for the blockage of the discharge port of the jaw crusher?

1. When the jaw crusher is running, the materials are crushed through the circulating motion between the movable jaw and the fixed jaw. When the movable jaw is far away from the fixed jaw, it is the process of discharging. Once the material falls in this process, the speed If it is too slow, a large amount of material will be blocked in the crushing cavity, which will cause the discharge port of the jaw crusher to be blocked.

2. The main transmission method of the jaw crusher is to drive the flywheel to rotate with high speed inertia through the V-belt. To drive the pulley, two conditions must be met: ① The motor has sufficient power; ② The V-belt is strong enough.

Generally, the V-belt is prone to failure. If the V-belt becomes loose and breaks, a large amount of material will not be crushed in the crushing cavity, and will be blocked in the crushing cavity and cannot be discharged, forming a blockage.

3. Another reason that easily causes the discharge port of the jaw crusher to be blocked is that the fastening bushing of the eccentric shaft of the jaw crusher is loose. When the eccentric shaft bushing is loose, the eccentric shaft will be stuck and the eccentricity will be blocked. When the shaft cannot rotate, the movable jaw cannot continue to rotate, resulting in the discharge port being blocked and the material unable to come out.

4. The motor of the jaw crusher requires a certain voltage to work properly. If the voltage of the jaw crusher is too low when it is running, there will not be enough power to drive the equipment to crush the materials. In this case, there will be a large amount of stone in the crusher. The crushing cavity is clogged, resulting in material blockage and shutdown.

5. The main bearing of the jaw crusher is the main power component responsible for the rotating crushing of materials by the equipment. If the main bearing fails and is damaged, it will seriously affect the production * of the jaw crusher and cause the discharge port of the jaw crusher to be blocked.
