Talc is a hydrothermal alteration mineral. Hydrothermal minerals often change into talc by hydrothermal alteration, so talc is often present in olivine, clinopyroxene, amphibole, tremolite and other minerals. Talc is a common silicate mineral, it is very soft and has a creamy feel. 10 minerals have been chosen to represent 10 hardness levels, known as the Moss hardness, and the first (and the softest) is the talc in these 10 levels. Soft talc can chalk out white marks instead of chalk. The talc is usually blocky, leaf like, fibrous or radial, white in color, gray in color, and colored with other impurities. There are many uses of talc, such as refractories, paper, rubber fillers, pesticide absorbents, leather coatings, cosmetics and carving materials, and so on.

Talc grinding mill generally refers to three ring, four ring superfine mill. Three ring four ring superfine mill adopts the method of grading and continuous grinding to carry out repeated cyclic grinding of materials at the same time, so as to realize superfine grinding. Three ring four ring superfine mill is a superfine powder mill developed according to the needs of the domestic superfine powder market. Tricyclic tetracyclic superfine grinding machine is mainly used for crushing barite, limestone, ceramic, slag fine powder processing, high humidity below 6% non flammable and explosive mines, metallurgy, chemical industry, building materials and other industries more than 280 kinds of materials.

Superfine powder processing Mohs hardness of less than or equal to 6 grade non flammable and brittle materials, such as calcite, chalk, limestone, dolomite, silica, kaolin, bentonite, talc, mica, vermiculite, illite, Ye Lashi, sepiolite, palygorskite, rectorite, diatomite, barite, gypsum, alum stone, graphite, fluorite, phosphorite, pumice and other 100 kinds of materials, fine powder product size in the 300-3000 project between the adjusted yield up to 0.7-7.5 tons per hour. Shanghai clirik HGM series superfine powder mill has five kinds of models, namely HGM80, HGM90, HGM100, HGM125, HGM1680L (new type).
