What is Talc?

Talc is a common seen silicate mineral that belonging to the trioctahedral mineral, its structural formula is (Mg6) [Si8] O20(OH)4. Talc is a hydrothermally altered mineral and contains asbestos, generally in lumpy, leafy, fibrous, or radial, with a very soft and smooth feel. In this paper we will provide you with the talc powder solution.


The Applications of Talc

Talc has the excellent physical and chemical properties of lubricity, anti-adhesion, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good hiding power, softness, good gloss, and strong adsorption. Therefore, it has a diverse applications in the industries of cosmetics, medicine, papermaking, plastics, and etc.


·Cosmetics industry

It is used in various emollient powder, beauty powder, talcum powder, etc. , with the function of blocking infrared rays, thus to enhance the sun-proof and anti-infrared property of cosmetics.


·Medicine and food industries

Additives for pharmaceutical tablets, pharmaceutical powders (such as acaphenol powder), sugar coatings, gardenia powder and traditional Chinese medicine prescriptions, food additives, release agents, etc. Featuring non-toxic, tasteless, high whiteness, good tolerance, strong gloss, soft taste, strong smoothness.


·Coating industry

After being processed by talc grinding machine, it is used for white extender pigment and various water-based, oil-based, resin industrial coatings, primers, protective paints, etc., to enhance product shape stability.


·Paper making industry

It is used as filler for paper and cardboard, and wood pitch control agent. It makes paper smooth and delicate , save raw materials, and improve the service life of grease nets.


·Plastic industry

It is used as filler for plastics such as polypropylene, nylon, polyvinyl chloride, polyethylene, polystyrene and polyester. Increasing tensile strength, shear strength, flexural strength, compressive strength, and reduce deformation.


·Rubber industry

It is used as rubber filler and anti-sticking agent for rubber products. Increasing the stability of product shape, increase strength of tension, shear, bend, and compression.


·Cable industry

It is used for cable rubber additive, cable isolator.


·Ceramic industry

It is used in manufacturing electric porcelain, radio porcelain, various industrial ceramics, building ceramics, daily ceramics and enamels. With the features of no discoloration at high temperature, increased whiteness after calcination, even density, good gloss and smooth surface.


·Waterproof material

It is used for waterproof membrane, waterproof coating, waterproof ointment, etc.



Talc milling process


Talc raw material composition analysis

 Note: Talc has obvious diversities from different places, especially if the SiO2 content is higher, it is more difficult to wear.

Model selection of Talc grinding mill


Note: 1. Select the main mill according to the capacity and fineness requirements;

Phase 1: Crushing the raw materials

Talc blocks are crushed by the crusher to the size of 15mm-50mm and into grinding mill.

Phase 2: Grinding

The crushed coarse talc are sent to the storage hopper by the elevator, and then sent to the grinding chamber by the feeder for grinding.


Phase 3: Classification

The ground material is classified by the classification system, and the unqualified powder will returned to the main mill to be reground.


Phase 4: Collection of finished products

The qualified fine talc powder enters the dust collector through the pipeline along with the airflow for separation and collection. The collected finished powder is sent from the conveying device to the finished product bin through the discharge port, and then packed by a powder tanker or automatic packer.
