The use of compressive crushing equipment such as gyratory crushers within minerals processing plants can potentially generate large quantities of dust. Remedies to this problem include the retrofitting of shrouds, enclosures, local exhaust ventilation At present, the “inorganic crusting type” dust suppressant is only applicable to static dust suppression in slopes of coal mine dumps and “undisturbed areas,” such as end slopes.

Dust control for the crushing and grinding processes is normally achieved by either wet suppression or local exhaust ventilation (LEV) systems, or a combination of both. Spraying the ore with water sprays to coat the outer surface helps to prevent dust from becoming liberated. Applying the water to the ore before it enters the crushing orCrushing dust removal systems are used to deal with the dust generated by the process of perforation, rock drilling, blasting, shipping and crushing of open pit mining or underground mining of mine crushing.

The model included unloading port of crushing station, dust suppression cover, dump truck and surrounding drainage basin. In order to ensure the calculation effect, the dimension of the outflow field is set as 30 m in length, 25 m in width and 25 m in height considering the area affected by the ambient wind. The load of dump truck was set to 401. Introduction. In coal mining activities, dust is generated by shearers and roadheaders mechanically crushing the coal, and then spreads to the whole working space, endangering the health of coal workers [[1], [2], [3]].Grasping the dust generation laws of different coal types is crucial for studying the laws of dust diffusion in the flow field and Analysis on the impact crushing dust generation test method
