Talc Powder Grinding Mill

Talc is a kind of silicate mineral, belongs to trioctahedron mineral, the structural formula is (Mg6)[Si8]O20(OH)4. Talc generally in bar, leaf, fiber or radial pattern. The material is soft and creamy. The Mohs Hardness of talc is 1-1.5.

Usage of Talc
Talc has high performances of lubricity, sticky resistance, flow-aiding, fire resistance, acid resistance, insulativity, high melting point, inactive chemical property, good covering power, soft, good gloss, strong adsorption. So, talc has wide application in cosmetic, medicine, paper making, plastic and other fields.

1. Cosmetic: applied in skin moisten, after shave powder, talcum powder. Talc has the function of obstructing infrared ray, so it can improve the performance of cosmetics;

2. Medicine/food: applied in medicine tablets and powder sugar-coating, prickly heat powder, Chinese medicinal formulae, food additives, etc. The material has the advantages of non-poisonous, tasteless, high whiteness, good glossiness, soft flavor and high smoothness.

3. Paint/coating: applied in white pigment and industrial coating, base coating and protective paint, stability of the paint can be increased.

4. Paper-making: used as the filler of paper and paperboard. The paper product can be smoother and finer. It can also save up raw material.

5. Plastic: used as the filler of polypropylene, nylon, PVC, polyethylene, polystyrene and polyester. Talc can increase the tension strength, shearing strength, twisting strength and pressuring strength of plastic product.

6. Rubber: used as filler and adhesive of rubber.

7. Cable: used to increase cable rubber performance.

8. Ceramic: applied in electro-ceramic, wireless ceramic, industrial ceramic, construction ceramic, domestic ceramic and ceramic glaze.

9. Waterproof material: applied in waterproof roll, waterproof coating, waterproof ointment, etc.

Talc Powder Grinding Mill can be used to grind barite, calcite, kalium, steatite, marble, glass, feldspar, etc. Raymond grinder (Raymond mill) is widely used in the metallurgy, building, chemical industry, and mining field..

Pyrophyllite Micro Powder Grinding

Pyrophyllite is a phyllosilicate mineral composed of aluminium silicate hydroxide: Al2Si4O10(OH)2. It occurs in two more or less distinct varieties, namely, as crystalline folia and as compact masses; distinct crystals are not known.
The compact variety of pyrophyllite is used for slate pencils and tailors chalk (French chalk), and is carved by the Chinese into small images and ornaments of various kinds. Other soft compact minerals (steatite and pinite) used for these Chinese carvings are included with pyrophyllite under the terms agalmatolite and pagodite.
Pyrophyllite is easily machineable and has excellent thermal stability. Therefore it is added to clay to reduce thermal expansion when firing but it has many other industry uses when combined with other compounds, such as in insecticide and for making bricks. Pyrophyllite is also widely used in high-pressure experiments, both as a gasket material and as a pressure-transmitting medium.

Pyrophyllite Micro Powder Grinding has been widely used in making fine powder or micro powder, which is applicable to non-flammable and non-explosive materials with hardness less than 6, such as the calcite, chalk, limestone, dolomite, kaolin, bentonite, talcum, talc, diatomite, barite, gypsum, alum earth, graphite, fluorite, etc.

Gypsum Micro Powder Grinding

Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O.It is widely mined and is used as a fertilizer, and as the main constituent in many forms of plaster, blackboard chalk and wallboard. A massive fine-grained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many cultures including Ancient Egypt, Mesopotamia, Ancient Rome, Byzantine empire and the Nottingham alabasters of medieval England. It is the definition of a hardness of 2 on the Mohs scale of mineral hardness. It forms as an evaporite .mineral and as a hydration product of anhydrite.

Commercial quantities of gypsum are found in the cities of Araripina and Graja in Brazil; in Pakistan, Jamaica, Iran (world’s third largest producer), Thailand, Spain (the main producer in Europe), Germany, Italy, England, Ireland, Canada and the United States. Large open pit quarries are located in many places including Plaster City, California, USA, and East Kutai, Kalimantan, Indonesia. Several small mines also exist in places such as Kalannie in Western Australia, where gypsum is sold to private buyers for changing the pH levels of soil for agricultural purposes.

Uses of Gypsum

Gypsum is used in a wide variety of applications:

Gypsum board is primarily used as a finish for walls and ceilings, and is known in construction as drywall, wallboard, sheetrock or plasterboard.
Gypsum blocks are used like concrete blocks in building construction.
Gypsum mortar is an ancient mortar used in building construction.
Plaster ingredients are used in surgical splints, casting moulds and modeling.
Fertilizer and soil conditioner: In the late 18th and early 19th centuries, Nova Scotia gypsum, often referred to as plaster, was a highly sought fertilizer for wheat fields in the United States. It is also used in ameliorating high-sodium soils.
A binder in fast-dry tennis court clay
As alabaster, a material for sculpture, it was used especially in the ancient world before steel was developed, when its relative softness made it much easier to carve.
A wood substitute in the ancient world: For example, when wood became scarce due to deforestation on Bronze Age Crete, gypsum was employed in building construction at locations where wood was previously used.
A tofu (soy bean curd) coagulant, making it ultimately a major source of dietary calcium, especially in Asian cultures which traditionally use few dairy products
Adding hardness to water used for brewing
Used in baking as a dough conditioner, reducing stickiness, and as a baked-goods source of dietary calcium
A component of Portland cement used to prevent flash setting of concrete
Soil/water potential monitoring (soil moisture)
A common ingredient in making mead
In the medieval period, scribes and illuminators mixed it with lead carbonate (powdered white lead) to make gesso, which was applied to illuminated letters and gilded with gold in illuminated manuscripts.
In foot creams, shampoos and many other hair products
A medicinal agent in traditional Chinese medicine called shi gao
Impression plasters in dentistry
Used in mushroom cultivation to stop grains from clumping together
Test have shown that gypsum can be used to remove pollutants such as lead from contaminated waters.
