Product Details

This micro-powder mill is mainly suitable for various non-flammable and brittle materials with medium and low hardness and Mohs hardness lower than 6, such as calcite, chalk, calcium carbonate, dolomite, kaolin, bentonite, talc, mica, and diamond Magnesium ore, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomaceous earth, barite, gypsum, alum stone, graphite, fluorite, phosphate ore, potassium ore, pumice, etc. . It is an ultra-fine grinding equipment developed for users of ultra-fine powder processing based on the current technology of the domestic milling industry and market demand, drawing on the technology of the milling industry.

Working principle

The motor drives the main shaft and every turnplate through the reducer. The reducer drives dozens of rollers to rotate against race way of ring through pin. Small material crushed by hammer crusher is transported into hopper by elevator, and then vibrating feeder shall feed material to the central part of upper turnplate evenly. The material falls to circle under the centrifugal force and comes down to raceway of ring to be crushed into powder. After grinded in the first race way, the material goes to the second and third turnplate. The blower inhales the external air into the mill and carries the powder after third turnplate into powder-separator. Turbine in the separator makes the coarse powder drop down and regrinded and the fine powder shall go into cyclone powder collector together with air current and go down through discharge valve as final product; at the same time, air current with a little dust goes out through blower and muffler after purified by filter.

Benefits Features

1. Efficient

Compared with jet mill, mixing grinder and ball mill of same finished product size and motor power, MW Micro-Powder Mill has double capacity and saves 30% energy.

2. Long Life of Spare Parts

Forged by special material, the ring and roller can be used for about one year while grinding calcium carbonate.

3. High fineness and flexible adjustment

The product size can be adjusted between 325 mesh to 2500 mesh (47-5micron).2. Long Life of Spare Parts

Forged by special material, the ring and roller can be used for about one year while grinding calcium carbonate.

4. Environmentally friendly

The application of pulse dust collector and muffler greatly reduce dust pollution and noise.
