In the working process of the jaw crusher, there is a blockage phenomenon that the material does not come down, which directly affects the next production. So, what are the reasons for the jaw crusher blocking material? How to solve it? Understand the following four points, so that you are no longer bothered by the jaw crusher.

1. High moisture content or high viscosity

 In the working process of the jaw crusher, if the water content of the ore is high, after entering the crushing chamber, the material containing moisture is broken into small pieces, which will stick together and block the two jaws in the crushing chamber. Directly, causing blockage. Or the material is mixed with the viscous mud, so that the material is stuck into a piece of the crushing cavity, and the blockage phenomenon occurs. If it is used for a long time, it will not only affect the production efficiency, but also the material sticking to the jaw plates will corrode the jaw plates and accelerate the wear of the jaw plates.

 Solution

Before the material enters the jaw crusher, the material is sieved and dehydrated to reduce the moisture and viscosity of the material. Dewatering can be done by air drying or by selecting a drying device.

2. The amount of feed is too large

In the production process of the jaw crusher, some operators in order to speed up the production schedule, increase the amount of feed, beyond the normal production capacity of the jaw crusher, the material can not be broken in time in the crushing chamber, resulting in blockage.

Solution

Professional training for operators to understand and familiarize with the relevant knowledge of jaw crushers, to achieve continuous and stable feeding, can effectively reduce the occurrence of blocking phenomenon.

3. Improper adjustment of the discharge opening

The occurrence of the blockage phenomenon may also be due to the fact that the discharge port is too small, the broken material cannot be discharged in time, and a large amount is accumulated in the crushing cavity, causing the blockage.

Solution

Appropriately adjust the discharge port of the jaw crusher and increase the size of the discharge port so that the crushed material can be discharged smoothly from the discharge port.

4. Do not understand the parameters of the jaw crusher

Before use, the parameters of the jaw crusher are not first defined, especially the requirements of the material properties. The material does not meet the production process requirements of the jaw crusher. After entering the crushing chamber, the ideal crushing effect is not achieved, and the production efficiency is lowered, resulting in blockage.

Solution

Before using the jaw crusher for production work, the parameters of the jaw crusher used, especially the material properties, should be clarified. According to the relevant requirements of the jaw crusher for materials (such as size, hardness, etc.), put the appropriate materials.

Blocking is a very easy phenomenon in the production process of jaw crushers, but as long as the cause is found, it is easy to solve according to the correct method.
