Calcite grinding mill is suitable for processing medium and low hardness non flammable and explosive brittle materials with 6 or less than 6 grade Mohs hardness, such as calcite, chalk, limestone, carbon black, kaolin, bentonite,
Raymond mill (also can be called Raymond Grinder) is used for grinding materials in the fields of building materials, mining, metallurgy and chemical industry.
High pressure micropowder mill is mainly formed by mill body, blower fan, ultra-fine analyzer finished product cyclone container, bag de-duster and air pipe.
The high-strength raymond mill size is adjustable in the range of 80-425 (1000 the finest) meshes. It is possible to product 30-80 mesh coarse powder through special device in the machine.
Ultrafine Mill is a kind of high efficiency grinding machine, which has up to 3250 meshes fineness, 30-800kg/h production capacity and high regulatory.
Barite can be used as white pigment, aggregate of radiation protection, the padding of chemical, paper and textile fields and the cosolvent in the glass production.
