Before introducing the description of Raymond Mill’s processing of coated calcium carbonate, we will introduce coated calcium carbonate at first.

First, the level of coated calcium carbonate is introduced. At this stage, the coated calcium carbonate can be divided into pre-coating grade and topcoat grade. Of course, the product developed for gloss or glossiness is generally calcium carbonate. The level is also measured by the 2 nanometer particle diameter. The precoated coated calcium carbonate refers to a view or function that is not directly apparent, but which gives the most suitable conditions for topcoat application. The usual function is to improve smoothness, fineness and micro-roughness. Therefore, coated calcium carbonate powder is particularly suitable for adaptation.

Calcium carbonate for top coating usually has a very small fine particle size, 90% or more is less than 2 UM, and even a small product. For coated calcium carbonate, high solids content is a more favorable application condition, so this grade of calcium carbonate powder is more widely used.

Therefore, the comprehensive processing of coated calcium carbonate is the most problem we need to solve at present. The selection of good grinding equipment is the basis for better processing. Taking full play of its due function, Guilin Hengda Mining Machinery Co., Ltd. has been engaged in the production of grinding machines more than 10 years, producing a wide range of applications for calcium carbonate grinding equipment, and the most widely used sales at this stage. The grinding equipment is HD series high efficiency raymond mill, here is the features of it as following:

Max feeding size: ≤35mm

Main motor power:45-315KW

Capacity: 1-60t/h

Final product size: 80-400 mesh

Applications : For non-metallic minerals with a Moh’s hardness of 6-9 and moisture content of 6% or less, it has a high productivity and high grinding power, such as talc, calcite, calcium carbonate, dolomite, , Kaolin, clay, graphite, zircon sand, bentonite and other non-metallic minerals.
