Talcum powder is divided into two types: fine talcum powder and fine talcum powder according to the size of its crushed particle size. According to different industrial uses, finely ground talcum powder can be divided into 7 varieties:
Coating grade talcum powder: used for white body pigments and various water-based, oil-based, resin industrial coatings, primers, protective paints, etc.
Paper grade talcum powder: used as filler for all kinds of paper and cardboard, wood asphalt control agent
Plastic grade talc: used as filler for polypropylene, nylon, polyvinyl chloride, polyethylene, polystyrene, polyester and other plastics
Rubber grade talcum powder: used for rubber packing and rubber products anti-sticking agent
Cable grade talcum powder: used for cable rubber intensifier and cable isolating agent
Ceramic-grade talcum powder: manufacturing electric porcelain, radio porcelain, various industrial ceramics, architectural ceramics, daily-use ceramics and porcelain glazes, etc.
Waterproof material grade talcum powder: used for waterproof coiled material, waterproof coating, waterproof ointment, etc.
Fine talcum powder: advanced paint coatings, plastics, cable rubber, cosmetics, copper paper coatings, textile lubricants, etc.

The main motor drives the main shaft and the turntable to rotate through the reducer, and the turntable drives dozens of ring rollers to roll and rotate in the grinding ring raceway through the pin. The bulk material is crushed into small particles by the hammer crusher and then sent to the storage bin by the elevator. The electromagnetic vibrating feeder evenly sends the material to the bulk tray on the upper part of the turntable, and the material is scattered into a circle under the action of centrifugal force. The periphery, falling into the raceway of the grinding ring, is punched, crushed, ground and crushed by ring rollers. After the first layer is crushed, the material falls into the second and third layers. The suction effect of the high-pressure centrifugal fan sucks in the outside air. Inside the machine, and bring the crushed materials into the powder concentrator. The rotating turbine in the powder concentrator makes the coarse particles fall back and regrind. The fine powder enters the cyclone powder collector with the airflow and is discharged by the discharge valve at the lower part of the cyclone as a finished product. The airflow with a small amount of fine dust undergoes pulse dust removal. After being purified, the filter is discharged through a fan and a muffler.
