Talc Powder Production Line

Talc Powder Production Line


Talc Powder Application

Ultrafine Talc is one of the world’s largest amount of ultra-fine powder products, widely used in papermaking, plastics, rubber, paint, cosmetics, ceramics, etc. Currently Talc Powder Production Line mainly uses the dry process. Although research wet pulverization, it is rarely used in industry.

Talc Powder Production Line

Talc Powder Production Line principles are as follows: slippery stones – crushing – drying – in pieces – fine grinding (Raymond) – ultrafine grinding (fine grinding) – Cyclone Aggregates – packaging production process is roughly slippery stones first by the feeder into jaw crusher for crushing; crushed material by bucket elevator and feeder into the vertical drying machine; talc dried and then the thin Crushing crusher backward Ru Leimeng After grinding fine grinding finely ground talc into ultrafine mill ultrafine grinding, talcum powder fineness can reach the final 500-5000 mesh (d97 = 30-5um). Specific processes are as follows:

1. Talc Powder Production Line – Ore-dressing

Talc flotation beneficiation can be divided, hand-selected, magnetic, optical pick-election. Due to natural talc floatability good, so hydrocarbon oil collector to flotation. The collector used is kerosene, oil as flotation frother. Methyl isobutyl carbinol (MIBC) brittle foam generated easily obtain high-quality concentrate. Talc flotation process is relatively simple, just a roughing, a sweeping election featured 2-4 times can get the final concentrate. Hand-selected based on talc and gangue minerals of different creamy hand pick and choose. Talc concentrate has a fine addition to the requirements givers, but also has a certain degree of whiteness, talc concentrate has a fine addition to the requirements givers, but also has some whiteness. Talc and mineral impurities using different surface properties of the optical industry and sorting method called optical inspection election.

2. Talc Powder Production Line- Ore Crushing

Selective crushing and screening. Use of talc and gangue minerals crushing and shape differences in terms of selectivity, using alternating circular impact crushing and screening methods, able to isolate most of the associated quartz and more than half of carbonate minerals.

3. Talc Powder Production Line – Fine Grinding

Talc powder state are ultimately to apply, so finely ground talc and ultrafine grinding is necessary processing technology. Talc Mohs hardness of a natural can be Crushing and grindability good. Finely ground talc, general domestic use various types of Raymond Mill or MTW Milling Machine, mainly produce 200 mesh and 325 mesh products, but if you set the fine grading equipment, can produce 500-1250 purpose products.
