Description

A dust-proof stone crusher

Technical Field

The utility model relates to the technical field of crushing, in particular to a dust-proof stone crusher.

Background Art

A mine is an independent production and operation unit that mines ores within a certain mining area. A mine mainly includes one or more mining workshops (or pits, mine shafts, open pits, etc.) and some auxiliary workshops. Most mines also include ore dressing plants (coal washing plants). Mines include coal mines, metal mines, non-metallic mines, building materials mines, chemical mines, etc.

After the ore is mined, it is mostly large stones that need to be broken into suitable sizes by a crushing device before they can be used. This requires the use of a crusher to crush the stones.

The crusher can crush the material into small materials of different sizes according to the requirements. During the material crushing process, a large amount of dust will be generated because the large materials are crushed into small materials. Since the feed port and discharge port of the crusher are directly connected to the external environment, the dust generated in the crushing process will be blown into the air through the discharge port and feed port, causing serious pollution to the air.
