Jaw crusher jaw plate wear reasons

       Jaw crusher jaw crusher is one of the important parts of the device, and therefore subject to wear and tear in the production of more paper describes jaw crusher jaw plate wear causes.

For their own reasons

1, the jaws of improper manufacturing materials, manufacturing processes or improper jaw, will be the quality of the jaw crusher is not guaranteed, their poor strength and wear resistance, so that the jaws wear in the short-term use serious.

2, in the production process of jaw crusher, if the wedge-shaped compact wedge surface is worn or edge guards on the jaws when clamping force is not enough, it will make jaws loose and strike other parts of the device, not only causing damage to other components, but also make the jaw severely worn.

Undesirable material

1, the hardness of the material to be broken, feed size, density and so affect the wear of the jaws, the harder the material, the more severe jaw plate wear, the greater the material size, will exacerbate friction between the material and the jaws effect, so that the jaws wear more.

2, on the other hand, when there are impurities into the crushing cavity, and jaw crusher safety device has not its normal protective effect, will cause severe damage to the jaw.

Material blockage

1, into the jaw crusher cavity material can not be too much, otherwise the material clogged material in sliding jaws squeezed increase, exacerbating jaw wear while generation due to wear, so nip angle is increased further, jams worse, creating a vicious cycle.

2, jaw crusher eccentric shaft speed is too fast, movable jaw plate swing too many times, causing the material had been broken too late to cause the crushing chamber discharge blocked, causing the jaws wear.
