Ultrafine mill is ideal grinding equipment for grinding calcium carbonate powder, which has comprehensive mechanical grinding performance such as roll, grinding, impact, environmental protection, energy saving, noise reduction, complete set, high efficiency, low energy consumption, equipped with pulse dust collector of 99% efficiency of dust collection. At present, it can be widely used at dolomite, calcium carbonate, marble, limestone, feldspar and barite and so on.

Vertical roller mill is economical and practical ultra-fine powder processing equipment. It can deep-process various non-metallic ores with Mohs hardness less than 7 and humidity less than 6%. 

Among them, Vertical roller mill is a large-scale ultra-fine ring roller mill, which has been appraised by China Calcium Carbonate Association as energy-saving and consumption-reducing equipment in the field of calcium carbonate processing in China. It has become the mainstream equipment in the field of non-metallic mineral fine powder processing, and is also used in the field of calcium carbonate grinding mill equipment.
