The Damage to Jaw Crusher from Dust Pollution

January 23, 2018

Jaw crusher is the first choice to crush the ores in the sandstone production line. It is usually used for coarse crushing. Compared with the common stone crushers, jaw crusher can crush the minerals with the large hardness and bigger size. Because of the bad working environment, Henan Fote reminds that users must focus on the working process of jaw crusher, especially the problem of dust pollution need to be valued.

In order to reduce the dust caused by the air leakage of crusher’s case, during the actual production, the dry material is often watered at the entrance of the equipment. But this operation is wrong, because it will exacerbate the paste bag of the filter bag of the sack-duster and the blocking of the unloading device.

In the falling process of the ores and other materials on the conveyor belt , the materials and air will enter into the closed dust hood, and the gas containing dust will diffuse to the outside of the case through the gap and orifice of the cover wall. In addition, there is almost no influence on the drop dust of the subordinate belt, whether the dust collector is start or not, because of the improper setting of the dust removal point in the corner of the belt machine. The dust collector doesn’t operate since the operation of jaw crusher. As a result, the subordinate conveyor belt is always being the process of dust pollution.

When the humidity of the crushed materials of jaw crusher is high, the elbow part is easy to be worn and clogged, and the dust particles that entering into the dust removal device are coarser than that of the dry materials. As a result, the sack-duster is easy to be pasted, and the unloading device is blocked easily, which can cause the ventilation resistance of the sack-duster increase greatly, and then the ventilation ability will be reduced. Finally, jaw crusher will be worn.
