Because of stone crusher is not fully closed, at work, being hit by extrusion, stone, stone clearance of air is extruded and high-speed outward movement, lead dust overflow together, instantly raise large amounts of dust. Dust discharge flow down through the chute (few) or through the feeding mouth upward (most), make the feeding mouth around produces a high concentration of dust. Under this state for a long time will not only cause serious pollution to the environment, will cause great harm to human body. So the control of dust pollution of the crusher, as a professional equipment manufacturers, we should make improvement measures from the aspects of what? The following Liming heavy industry is to introduce some stone crusher dust control methods.
1. The closed control dust source in seal cover seal, spread the scope of dust is not as much as possible.
2. Eliminate the hopper, shield height potential difference handling equipment, chute, etc for powder, high potential difference generated by the difference of the main causes of spillover is the dust float in the sky, try to reduce the gap, reduce the chute chute inclination, some secret chamber caused by negative pressure best closed, such ability for dust collection.
3. Wet dust removal and exhaust dust removal according to the reasons of the dust, dust source can be set respectively control countermeasures: in the feeding mouth and tape transshipment point setting spray device, and to control the amount of water wet stone, can significantly reduce the crushing plant transfer point inside the dust pollution; When transfer point particularly poor ventilation, transporting underground buildings should use centrifugal fan, forced ventilation, dust reinforced platoon wind speed, air volume; When the tape running produce dust, the use of negative pressure bag filter dust source of risk control system.
