The invention belongs to the technical field of
coating production equipment, and particularly relates to a
coating sand mill for producing an environment-friendly low-
carbon coating. The
coating sandmill comprises a motor output end fixedly connected with a motor, a cold water chamber is arranged on the lower portion of the motor output end, a drainage
impeller is arranged in the cold water chamber, the drainage
impeller is fixedly arranged at the motor output end in a sleeving mode, a sand milling cylinder is arranged below the cold water chamber, a plurality of
grinding pieces are fixedlyconnected to the side face of the motor output end, the outer side of the sand milling cylinder is sleeved with a cooling outer partition plate, a water passing cooling layer is arranged between the cooling outer partition plate and the sand milling cylinder, the upper end of the water passing cooling layer communicates with the lower side of the cold water chamber, a plurality of
sieve holes which are annularly distributed by taking the motor output end as the circle center are formed in the bottom of the sand milling cylinder, a screen is arranged in each
sieve hole, and a storage chamber isarranged at the lower end of the sand milling cylinder. According to the coating sand mill, cooling water can be greatly saved, and meanwhile, the
cooling effect of the sand milling cylinder is guaranteed.
