Dust pollution problem of jaw crusher

The jaw crusher is the main crushing equipment of the ore production line. It is generally used for coarse crushing of ore. The larger size stone is broken into small pieces and then processed. Usually the jaw crusher works outdoors, the environment is relatively bad, when working. Dust will be generated, and we need to pay special attention to the dust pollution problem of the jaw crusher.

 
In order to reduce the dust caused by the air leakage of the crusher casing, in actual production, when the material is dry, water is often poured at the inlet of the crusher. In fact, this situation is wrong, which will aggravate the bag filter of the jaw crusher. The filter bag and the feeder are clogged.

During the falling process of the ore and other materials on the belt conveyor, the air enters the sealed dust hood together with the material, and the dust-containing gas diffuses outside the cover through the gaps and holes in the cover wall. In addition, due to the improper setting of the dust removal point at the corner of the belt conveyor The dust collector has almost no effect on the dust of the lower belt conveyor regardless of whether it is opened or stopped. Since the jaw crusher has been in operation, the dust collector has not been operated, and the lower belt conveyor has been in the process of dust pollution.
 
When the crushing material of the jaw crusher has a large humidity, the elbow portion is easily worn by the dust and the dust particles entering the dust collector are thicker than the broken dry material, and the bag type dust remover is easy to paste the bag, and the feeder is easy to block. As a result, the ventilation resistance of the bag filter is greatly increased, and the ventilation capacity is lowered, resulting in wear of the jaw crusher.
