Now among of mining machinery, equipment application is increasingly common. And the roll crusher is used most in mining machinery. Then in the ordinary operation of roll crusher, there will appear many mechanical or maintenance problems. Such as dust will continue to impact crusher production efficiency, we have to analyze this issue:
1) In the process of material falling above belt conveyor, both the air and the material went into a closed dust removing mask. Dust-laden gas spread through the cover wall cracks and openings to the hood, which leads to the environment polluted. In addition, due to the belt-corner dust points are set incorrectly, the precipitator is whether the open and stop on the lower belt conveyor drop dust has almost no effect. Therefore, crusher run, the dust collector is not running, the lower belt conveyor has been in the dust diffuse.
2) When the dust goes into the dust collector pipe, the inlet at the elbow increases the system resistance, elbow parts is susceptible to wear and clogging. The round screw conveyor and sub-grid transport bag filter to trap the dust down, power consumption increases, mechanical maintenance workload increase; It often needs to be demolished grid round under the feeder, over time, under the feeder flange air leakage exacerbate air leakage ash bucket.
3) When the broken material moisture (rain or materials tricking), into the dust of dust particles than the broken dry materials, rough, the bag house easy to paste bag, under the feeder is easy to plug, resulting in a dust bag control ventilation resistance is substantially increased, decreased ventilation capacity, severe dust.
4) Since the bag house is intermittent cleaning when the normal working hours of the precipitator grid round Leakage also can not be ignored. Bag house filter area selection is too small, insufficient amount of the actual ventilation, crusher dust cover of the discharge port and the crusher cavity is difficult to form a slightly negative pressure, resulting in the job environment dust.
5) Crusher bag house and the component parts have more problems, which not only affect the normal dust removing, and increase the maintenance workload of the equipment. Seen the statistics from equipment maintenance, the poor quality of equipments parts is the key factors causing equipment failure.
