Cause Analysis of Jaw Crusher Material Jam

1. The moisture content of the material is high and the viscosity of the material is high

During the working process of the jaw crusher, if the ore material with high water content enters the crushing cavity, the material containing moisture will be broken into small pieces, which will stick to each other and block the two jaw plates in the crushing cavity. Between, resulting in the phenomenon of material jam. Or the material is mixed with highly viscous rare earth, so that the material is stuck into a piece and blocked in the crushing cavity, resulting in material jamming.

Solution: Before the material enters the jaw crusher, prepare the material for screening and dehydration to reduce the moisture and viscosity of the material.

2. Do not understand the main parameters of the jaw crusher.

Before use, the parameters of the jaw crusher, especially the requirements for the nature of the material, have not been clarified first. The material does not meet the production process requirements of the jaw crusher. After entering the crushing chamber, the ideal crushing effect cannot be achieved, which reduces the production efficiency and causes the phenomenon of material jam.

Before using the jaw crusher, you should first clarify the parameters of the jaw crusher used, especially the requirements for the nature of the material. According to the relevant requirements of the crusher for materials, put in suitable materials. According to the requirements of the production process, such as too high temperature or too much moisture, the corresponding treatment work can be carried out first, so that the materials can meet or approach the requirements of the jaw crusher as much as possible, and then be sent into the crushing chamber for crushing.

3. Operators are not trained.

The operators of the jaw crusher have not received professional training, and they know too little about the relevant knowledge of the equipment and the precautions for operation. Cause the phenomenon of material jam.

The operation of the jaw crusher is best carried out by professionally trained technicians. The technicians are familiar with the relevant knowledge of the jaw crusher, which can effectively reduce the occurrence of material jamming.

4. Improper discharge adjustment.

The occurrence of material jamming may also be due to the fact that the discharge is too small, and the crushed material cannot be discharged in time, and a large amount of material is accumulated in the crushing cavity, resulting in the phenomenon of material jamming. The outlet of the jaw crusher should be properly adjusted to increase the size of the outlet so that the material can be discharged smoothly.

The technicians of OCP technical department said: the jamming phenomenon of jaw crusher is inevitable, but it is also easy to solve. As long as the user follows the correct operation method, carefully analyzes the properties of materials, and pre-treats special materials, the jamming can be completely reduced. The probability of the occurrence of the phenomenon, so that the smooth progress of production operations.
