Grinding Mill Plant For Calcium Carbonate

Calcium carbonate grinding millas a professional grinding mill manufacturer in china, zenith machinery can supply high quality calcium carbonate grinding mills for the clients all over the world.The calcium carbonate powder production plant for fine ground and ultrafine ground calcium carbonate consists of a ball mill, trapezium mill, or ultrafine mill in closed circuit with a high efficiency air classifier.The feed material like crushed calcite, aragonite, vaterite is fed pneumatically through a venturieductor into the grinding mill.The particles are pulverizer by a high speed agitated grinding media.The grinding media can be stainless steel, chrome steel, alumina or zirconia.The micronized particles are entrained in the air stream and exit the grinding mill in a high efficiency air classifier.The on size particles are separated and the oversize returned to the mill for regrinding.The grinding media does not discharge from the mill.The raw materials which are used to produce calcium carbonate can be calcite, marble, limestone,graphite, chalk, marble, travertine, dolomite, bones and teeth etc.The final powder of the grinding mill can be ground down to 3000mesh (or 5micron).Ultrafine grinding mill for calcium carbonatescm series ultrafine grinding mill is a fine powder and ultrafine powder production machine which can meet your fine particle processing, micronizing, fine dry grinding, air classification and other comminution requirements.The scm ultrafine mill is a dry airswept media mill used for the production of fine powders typically below 45 microns.The grinding capacity is from 350kg/h to 7 tph according to different models.The feed material must be suitable for pneumatic conveying, typically all below 3 mm.In addition to kaolin and talc, calcium carbonate is used in the paper industry as a filler and coating pigment in the production of paper.Since calcium carbonate is rhombohedral even when very finely ground, it is primarily used in papers with the highest degree of whiteness and good printability.Examples of these are coated printing papers or highly filled copy and office papers.
