Technical Field

The water supply ring fills water into the water spraying square ring through an offset ring and a vertical pipe. The inner ring surface of the water spraying square ring sprays water into the dust extraction cylinder. The air pump A extracts air from the feed end cover through the dust extraction cylinder.
