Talc powder is currently mainly used in the industrial production of plastics, medicine, paper making, cosmetics, coatings and other daily chemical industries. At present, there are different demands for 325 mesh ordinary talc powder to thousands of mesh fine talc powder in the market.
Low purity talc powder is mostly used in small and medium-sized paper mills, while high-purity talc powder is used in the production of coatings, medicine, cosmetics and other relatively good industries. Generally speaking, the fineness of talcum powder is affected by the production and processing equipment of talcum powder.
In terms of the production process of talc powder, generally speaking, the production of talc powder mainly includes three steps: beneficiation, crushing and grinding. The talc processing equipment required for different steps is different. Flotation, manual separation, magnetic separation and photoelectric separation are four different methods for talc beneficiation.
After beneficiation, quartz and carbonate minerals are separated from talc by using talc processing equipment through impact crushing and alternate use of circular screen, and then talc processing equipment comes into play.
At present, dry processing is the main processing method for talc powder processing. Based on the natural fragility and grindability of talc, the talc powder processing equipment used is mainly Raymond mill and air flow mill, which are the main processing equipment for producing 200 mesh, 325 mesh and 500-1250 mesh talc powder.
The dry production process of talcum powder is from selecting talcum blocks to coarse crushing, After drying and intermediate crushing, fine grinding and ultra-fine grinding are carried out. If the talcum powder mill with ultra-fine grinding is used, the talcum powder produced can reach a fineness of 500-5000 goals.
Ultra fine talcum powder is a large amount of ultra-fine powder products in the world at present, which can be used in industries such as paper making, plastic production, paint production, etc. However, with the continuous development of the plastic industry, talcum powder is also used to produce plastics for the automobile industry and electric power industry.
Therefore, the market has higher and higher requirements for talcum powder, which also promotes the continuous reform and innovation of talcum powder processing equipment. The higher the application level of talcum powder, the higher the requirements for the equipment of talcum powder mill. In order to reflect the output value of talcum powder, it requires more types of talcum powder processing equipment, such as ultra-fine mill and high-pressure suspension roller mill.
