Now the use of mining machinery is increasingly common, such as roll crusher. Then it will appear mechanical or maintenance problems in the ordinary course of roll Crusher, just like dust will continue to impact production efficiency, we have to analyze this issue:
1) 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.
2) 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, crusher run, the dust collector is not running, the lower belt conveyor has been in the dust diffuse.
3) 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.
4) 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.
5) Since the baghouse is intermittent cleaning when the normal working hours of the precipitator grid round Leakage also can not be ignored. Baghouse 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.
6) crusher baghouse and the failure of the component parts more, not only affect the normal dust, and increased the maintenance workload of the equipment. Look at the statistics from equipment maintenance, with the poor quality caused by equipment failure more important reason.

With its high quality products such as Screw classifier, Cone crusher manufacturer, Vibratory feeder, Vibrating feeder,Zhengzhou Huahong mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
