Talc Mining And Processing Solution2021-07-16

What Is Talc

Talc is a common silicate mineral, belonging to trioctahedral mineral, and its structural formula is (Mg6)[Si8]O20(OH)4.Talc is a hydrothermal altered mineral.Mg-rich minerals are often changed into talc by hydrothermal alteration, so talc often presents mineral false appearance such as olidine, encompyte, hornblende, tremolite and so on.Talc is one of the minerals that is buried in the ground with serpentinite, which contains asbestos, and so often contains asbestos in its natural form.Talc is usually lumpy, blade-like, fibrous or radiating. It is very soft and has a smooth feel.Talc soft, its for 1 ~ 1.5 mohs hardness coefficient, have slippery feeling, {001} cleavage is extremely full, easy to split into slices, natural rest Angle is small (35 ° ~ 40 °), very solid, the surrounding rock of silicide and petrochemical magnesite, lingmei rocks, lean ore or dolomitic marble, with a few solid medium, generally are not solid, joint, crack development,The physical and mechanical properties of ore and surrounding rock have great influence on mining technology.

The Use Of Talc

Talc has good physical and chemical properties such as lubricity, anti-adhesion, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good hiding power, softness, good gloss, strong adsorption and so on.Therefore, talc in cosmetics, medicine, paper, plastic and other fields have a wide range of applications.


Used for all kinds of moisturizing powder, beauty powder, talcum powder, etc.It has the function of blocking infrared ray, so it enhances the performance of sunscreen and anti-infrared ray of cosmetics.

In The Field Of Medicine And Food

It is used for medicine tablet, medicine powder (such as Agafen powder) icing, prickly heat powder, Chinese medicine prescription, food additive, isolation agent and other additives.It has the characteristics of non-toxic, tasteless, high whiteness, good receptivity, strong gloss, soft taste and strong smoothness.

Coating Area

For white body pigment and all kinds of water-based, oil-based, resin industrial coatings, primers, protective paints, etc.Increases the stability of the product shape.

Paper Making Field

Used for all kinds of paper and paperboard filler, wood asphalt control agent.The paper can be smooth, delicate, save raw materials, improve the service life of the fat net.

Plastic Areas

Used as filler for plastics such as polypropylene, nylon, polyvinyl chloride, polyethylene, polystyrene and polyester.Increase tension strength, shear strength, bending strength, pressure strength, reduce deformation.

Rubber Field

For rubber filler and rubber product anti - adhesion agent.Increase the stability of product shape, increase the tension strength, shear strength, bending strength, pressure strength.

Cable Field

Used as cable rubber additive and cable isolating agent.

Ceramic Industry

Used for manufacturing electric porcelain, wireless electric porcelain, various industrial ceramics, building ceramics, daily ceramics and enamels, etc.It has the characteristics of no discoloration at high temperature, enhanced whiteness after forging and burning, uniform density, good gloss and smooth surface.

Field of Waterproof Materials

Used for waterproofing coil, waterproofing coating, waterproofing ointment, etc.

Talc Pulverizing Host Selection Scheme

Note: 1.According to the output and fineness of the host machine;

The First Stage: Crushing Of Raw Materials

The talc bulk material is crushed by the crusher to the feeding fineness of the mill (15mm-50mm).

The Second Stage: Grinding

The crushed small pieces of talc material are sent to the storage hopper by the hoist, and then sent to the grinding room of the mill for grinding evenly and quantitatively by the feeder.

The Third Stage: Classification

The material after grinding is classified by the grading system, and the unqualified powder is classified by the classifier and returned to the main machine for re grinding.

The Fourth Stage: Collection Of Finished Products

The powder in line with the fineness enters the dust collector through the pipeline with the air flow for separation and collection. The collected finished powder is sent to the finished product silo through the discharge port by the conveying device, and then packaged by the powder loading tank car or automatic baler.
