Talc powder machinery production

Talc beneficiation and processing method

Chinese talc ore beneficiation extensively used hand-selected, dry-mill air classification. Though individual factories happen to be established column flotation choice procedure, it has not been widely applied. At present, these processes have currently completed their beneficiation investigation and testing, like optical choice method, bleach, dry or wet magnetic separation, hydrocyclone separation, scrubbing precipitation concentration, centrifugal classification, spray drying, and talcum powder layering method , sterilization and also other special processes. Talc processing not simply consists of milling operations, but in addition sorting the low-grade ore by flotation method, meanwhile complete recovery of advantageous associated minerals. Crushing equipment: Talc is usually crushed by jaw crusher. Milling equipment: such as basic and ultra-fine grinding gear. General grinding equipment typically consists of Raymond mill, mostly for the production of 200,325 mesh talc powder; ultra-fine grinding equipment like flat, circular tube, fluidized bed and other jet mill, mainly for the production in the diameter shorter than 5μm ultra-fine talc powder.

The two processes of talc powder production The very first procedure uses Raymond mill, mainly products 200,325 mesh talc powder, operating capacity: 325 mesh three.2 ~ three.8t / h, 200 mesh 4.four ~ four.8t / h; the input particle diameter shorter than 40mm; ore grade (SiO content): I grade 57%, II grade 53%, III grade 35%; power consumption 29 ~ 31kWh / t run-of-mine ore. The second procedure is the fine talc ore powder production line, the Zenith Machinery imported the technologies from Europe, as well as the production line consists of four parts: warm-dry, grinding, ultra-fine grinding and air compression system. Key and auxiliary equipment: 250mm × 400mm jaw crusher six sets, SZZ 1 250mm × two 500mm self-centering vibrating screen six sets, 5R Raymond six sets, GR-180 grinding machine two sets (for the jet mill preparation, Zenith production), flat-type jet mill 1 set.

Talc beneficiation practice - Liaoning Haicheng Talc Mine Haicheng talc mine is in Van Jiabao village Horse Wind town, which can be situated 24km southeast of Haicheng, was founded in 1949. It has grow to be a talc massive enterprise. The annual output talc are 150,000 t of and talc powder processing capacity of 160,000 t. The ores within this mine are white, gray, pink, etc. Along with the structures are lump, sheet and middle coarse-grained and disseminated, the key mineral is talc (55%), the associated minerals are magnesite (42%), and quartz (1.5%), the gangue minerals are pyrite (0.5%) as well as a smaller level of apatite, chlorite, serpentine, tourmaline, tremolite, rutile, graphite, and so on. The mine only utilizes dry-hand selection process currently. Hand choosing out +100mm I grade out from -350mm, then screening out -30mm II grade from -100mm ore, at final hand picking out I,III grade from -100+30mm ore. The main technical financial indicators are as follows: capacity of 115kt / a, ore grade of 50%, refined mineral price of 50%, concentrate grade of 94%, concentrate recoveries rate of 80% and tailings grade of 15%, processing power consumption ore four.1kWh / t.

Talc powder machinery production

Main talc highly-processed products’ kinds and uses 1. Paper making special I,II,III grade talc powder 2. Electric cable I,II grade talc powder Useing as the padding for cable, rubber and plastic, in order to improve their resistances of acidic and alkali, heat, impact strength, tensile strength and creep, also the thermal conductivity, electrical insulation and to improve the performance of rubber processing. 3. Ceramics I,II grade talc powder As the ceramics ingredients, it can effectively control the thermal expansion of the ceramic body, as the glaze, it can provide low-cost source of magnesium oxide. 4. Textile special I,II grade talc powder Talc can be used as the textile padding and brightener for its low wear and high degree of whiteness. 5. Paint and coatings I,II grade talc powder The talcum powder can easily dispersed in water and organic matter, with high chemical inertness and high oil absorption, it can improve the coating dispersion. 6. Pharmaceuticals I,II grade talc powder It can be used as cosmetics filler and pharmaceutical and food carriers, additives. 7. Talc carved products The I grade of industrial raw materials, can be made into workmanship and industrial pencil.
