Calcium carbonate superfine raymond mill is developed by our company experts on the basis of many years the production of industrial mill , who learn from Germany and Japan advanced fineness grading technology to solve the difficulties of the ultra-fine milling grading. Calcium carbonate is an inorganic compound , the main component of limestone rock (referred to as limestone) and calcite.
Calcium carbonate production process
First, hand-pick the calcite, limestone, chalk, shells, etc transported from the quarry, to remove the gangue; and then use the stone crusher for coarse crushing, and then ground by the calcium carbonate super fine mill to get the fine limestone powder, and finally with grading machine grading. And the powder that meet the size requirements are packaging storaged as product , otherwise, return back to calcium carbonate milling grinding machine again.
The use of calcium carbonate superfine mill
Calcium Carbonate Mill is mainly applied to low hardness, Mohs hardness of <6 **non-explosive brittle material ultra-fine powder processing, such as calcite, chalk, limestone, dolomite, silica, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, tired rectorite, diatomite, barite, gypsum, alunite, graphite, fluorite, phosphate rock, potassium ore pumice, etc. more than 100 kinds of materials. And fine finished granularity can be adjusted between 325-3000 mesh, yield up to 0.5-12 tons per hour.
Calcium Carbonate Mill working principle
The works of Mill is the same with R Series Raymond Mill. But set a high pressure spring in the milling device, so that the grinding pressure between the roller and grinding ring increase 1.2 times. When roller and grinding ring reach a certain wear and tear, by adjusting the length of high pressure spring can keep constant grinding pressure between the grinding roller ring in order to ensure stable quality. In the milling device, all parts are technical improved, so that the roller and grinding ring contact area is maximized, to avoid a general mill phenomenon that small particles of material that are in a rugged gap can not continuous crushed.
