Roller grinding mill is a new-type grinding mill, combining rolling, impacting and grinding to one. It is an ideal micro-power grinding mill for processing non-metal minerals such as calcium carbonate, barite, talc, gypsum, calcite, limestone, calcium oxide, bentonite, dolomite etc.

Working Principle:

Frequency-conversion feeder shall feed material to the central part of upper grinding-plate 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 raceway, the material goes to the second and third raceway. The air blower inhales the external air into the mill and carries the powder after third grinding-plate into classifier. Classifier wheel makes the coarse powder drop down and then regrinded, the fine powder shall go into cyclone 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.
