Jaw crusher discharge port clogging, find the cause, eliminate the problem from the source
Although the jaw crusher discharge opening blockage is a minor fault, it can affect the performance of the crusher and the subsequent process of the whole production line.
Once the blockage occurs during the jaw crusher operation, the feed should be stopped immediately, and the jaw crusher should be completely shut down to clear the blocked material and check the connection degree of each part, and re-fix the loose parts.
What are the main reasons for the blockage of the jaw crusher discharge opening? How to avoid blockage during maintenance?
1 When the jaw moves away from the fixed jaw, it is the process of discharging material. Once the speed of material falling in this process is slow, a large amount of material is blocked in the crushing cavity, which will cause the jaw crusher discharge opening to be blocked.
2 The main transmission method of the jaw crusher is to drive the flywheel through the v-belt for high-speed inertia rotation, and to be able to drive the pulley requires two conditions.
First: the motor power is sufficient.
Second: the v-belt is strong enough.
Generally, the v-belt is prone to failure. If the v-belt is loose and broken, a large amount of material cannot be crushed in the crushing chamber, and then blocked in the crushing chamber and cannot be discharged, forming a blockage.
When the eccentric shaft bushing is loose, it will cause the eccentric shaft to be stuck, and when the eccentric shaft cannot rotate, the moving jaw cannot continue to rotate, resulting in the discharge opening being blocked and the material cannot come down.
4 The motor of jaw crusher needs a certain voltage to work normally, if the voltage of jaw crusher is too low, there will not be enough power to drive the equipment to crush the material, then there will be a lot of stone blocked in the crushing cavity, leading to blockage and stoppage.
5 The main bearing of the jaw crusher is the main power component which is responsible for the rotation of the equipment to crush the material, the failure of the main bearing will seriously affect the production performance of the jaw crusher and finally make the discharge opening of the jaw crusher blocked.
Depending on the type of equipment, there are basically three ways to adjust the discharge opening of the jaw crusher as follows.
