In the working process of jaw crusher, sometimes the material is stuck and cannot come down, which directly affects the subsequent production. So, what are the reasons for jaw crusher jamming? How to solve it? Understand the following four points, so that you will no longer be bothered by jaw crusher jamming.
01 Materials with high moisture content or high viscosity
In the working process of jaw crusher, if the water content of ore is high, after entering the crushing chamber, the materials containing water will be crushed into small pieces, which will adhere to each other, and the two jaw plates blocked in the crushing chamber will directly cause material jamming. Or the material is mixed with thin clay with high viscosity, so that the material is stuck into a piece and blocked in the crushing cavity, resulting in material jamming. If this happens for a long time, it will not only affect the production efficiency, but also the materials adhered to the jaw will corrode the jaw and accelerate the wear of the jaw.
Solution: before the materials enter the jaw crusher, the materials shall be screened and dehydrated to reduce the moisture and viscosity of the materials. Dehydration can choose natural air drying or drying equipment.
02 Excess feed
In the production process of jaw crusher, some operators increase the feeding amount in order to speed up the production progress, which exceeds the normal production capacity of jaw crusher. The materials can not be broken in time in the crushing chamber, resulting in jamming.
Solution: conduct professional training for operators to make them understand and familiar with the relevant knowledge of jaw crusher, so as to achieve continuous and stable feeding, which can effectively reduce the occurrence of jamming.
03 Improper adjustment of discharge port
The material jam may also occur because the discharge port is too small, the crushed materials can not be discharged in time, and a large number of materials are accumulated in the crushing chamber, resulting in material jam.
Solution: properly adjust the discharge port of the jaw crusher and increase the size of the discharge port so that the crushed materials can be discharged smoothly from the discharge port.
04 The operator does not know the parameters of the jaw crusher
Before use, the parameters of jaw crusher, especially the requirements for material properties, were not defined first. The material does not meet the production process requirements of jaw crusher. After entering the crushing chamber, it can not achieve the ideal crushing effect, reduce the production efficiency and cause material jamming.
Solution: before using the jaw crusher for production, the parameters of the jaw crusher used, especially the requirements for the properties of materials, should be clear. Input appropriate materials according to the relevant requirements of jaw crusher for materials (such as size, hardness, etc.).
Jam is a very easy phenomenon in the production process of jaw crusher, but it is easy to solve as long as the reason is found and operated according to the correct method.
