Generally speaking, Lignite Mineral Sizer will set similar active start and stop control effect and central bin, this material level control is divided into front control, after control and comprehensive control of three.The front control is set in the front of the control bin feeding device, and the control refers to the control bin after the discharge device. Successively comprehensive control is to say that the central bin is equipped with high, medium and low three material level control device to separate the equipment and feed, so that the material level has been maintained between the high and low material level control device.
1. Lignite Mineral Sizer can use closed dust source + ventilation dust removal method to dust removal.In this way, the process is simple and the level of mechanization is high, it also adopt remote control, can effectively reduce and eliminate the contact of workers and dust.
2. Transport dust removal: vehicle dust is an important dust source in the transport process of coal in open pit mines. Main dustproof method: sprinkling water before loading, unloading ore spray; Strengthen the road surface protection, reduce the transport process of mining; The main transport road uses asphalt or concrete pavement and often sprinkles water, or adds wetting agent to the water to enhance the dustproof effect. Also available sprinkler spray moisture absorbent and polymer adhesive composed of dust suppressant dust, this dust suppressant can not only form a dust layer moisture absorption, but also improve the quality of the road.
3. Personnel should pay attention to personal protection. After the measures of ventilation and dust prevention are taken at the site of Lignite Mineral Sizer, although the dust concentration can be reduced to below the designated scale, there are still a large number of fine mineral dust suspended in the air, so enhancing individual protection is an important aspect of the comprehensive dust prevention steps. Personal protective equipment to avoid dust hazards is called respiratory organ protection equipment (respiratory equipment for short), which can be divided into clean air type, ventilation type and self-supporting type three. Dustproof mask is the most widely used breathing equipment in the work of mine workers, including simple simple and compound two.
