The damage of dust produced during the crushing process

Stone processing and other mining resources in the production process will produce a lot of dust, dust both pollute the environment and gave the health of workers caused tremendous harm, and therefore in the process of stone production line, to find a solution to the dust is necessary.
The production of the crusher, in addition to dust, there are still some problems, mainly:
1) When the broken material moisture (rain or materials tricking), into the dust of dust particles than the broken dry materials, rough, the baghouse 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.
2) baghouse filtration area of ??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, causing the dust of job environment.
3) belt conveyor material in a fall, the air and the material went into a closed dust mask, dust-laden gas through the cover wall cracks and openings to the hood spread, polluting the environment. 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, since the rock breaking machine running in the 5th, the dust collector is not running, the lower belt conveyor has been in the dust diffuse, the process layout of the transformation of the former belt-corner layout of dust
4) the dust into the dust collector pipe inlet at the elbow so that the system resistance increases, elbow parts susceptible to dust 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; often need to be demolished grid round under the feeder, over time, under the feeder flange air leakage exacerbate air leakage ash bucket.
5) In order to reduce air leakage due to the crusher housing caused by dust in the actual production, watering when the material is dry and often at the entrance to the crusher, the results of intensified baghouse filter bags paste bag and feeder blockage. Since the baghouse is intermittent cleaning, when the normal working hours of the precipitator, the separate compartments round air leakage is not be ignored.
