Talc powder production is generally divided into four types: talc coarse powder processing (0-3mm), fine powder processing (20-400 mesh), and ultrafine powder processing (400-1250 mesh) and micro-powder processing (1250 mesh — 3250 mesh).

The first stage: crushing of raw materials

The bulk talc material is broken by the crusher to the feeding fineness (15mm-50mm) that can enter the grinding machine.

The second stage: grinding

The small pieces of broken talc material are sent to the storage hopper by the elevator, and then are uniformly and quantitatively sent to the grinding room of the mill by the feeder.

The third stage: grading

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

Stage 4: Collection of finished products

The powder conforming to the fineness enters the dust collector with the air flow through the pipeline 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 is uniformly packed by the powder filling tank truck or automatic baler.

Use of talc
Talc has excellent physical and chemical properties such as lubricity, viscosity resistance, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good covering power, softness, good luster, strong adsorption. Therefore, talc in cosmetics, medicine, paper, plastics and other fields have a wide range of uses.

• Cosmetics field
  Used in various skin powder, beauty powder, talcum powder and so on. It has the function of blocking infrared rays, so it enhances the sunscreen and anti-infrared properties of cosmetics.

• Medicine and food
  Used in medicine tablets, medicine powder (such as acafol powder) icing, prickly heat powder and Chinese medicine prescriptions, food additives, isolating agents and other additives. It has the characteristics of non-toxic, tasteless, high whiteness, good tolerability, strong gloss, soft taste and strong smoothness. Coating field used in white body pigment and various kinds of water – based, oil – based, resin industrial coatings, primer, protective paint, etc. Increase the stability of product shape.

• Papermaking field
  Used for all kinds of paper and board filler, wood asphalt control agent. Can achieve smooth, delicate paper, save raw materials, improve the life of the fat net.

• Plastics field
  Used as filler for polypropylene, nylon, polyvinyl chloride, polyethylene, polystyrene and polyester plastics. Increase tensile strength, shear strength, bending strength, pressure strength, reduce deformation.

• Rubber field
  Used for rubber fillers and rubber products anti-stick agent. Increase the stability of the product shape, increase the tensile strength, shear strength, bending strength, pressure strength. Cable field used for cable rubber additive, cable isolation agent.

• Ceramic field
  Used in the manufacture of electric porcelain, wireless electric porcelain, various industrial ceramics, building ceramics, daily ceramics and porcelain glaze. It has the characteristics of no discoloration at high temperature, enhanced whiteness after forging and burning, uniform density, good luster and smooth surface.

• Waterproof material field
  Used for waterproof coil, waterproof coating, waterproof ointment and so on.
