KAOLIN GRINDING PLANT
Description of kaolin :
Pure kaolin have the features of high whiteness, good plasticity and high adhesion, excellent electrical insulation properties;.they are soft, and easy to disperse and suspended in water, with good plasticity and high adhesion, excellent electrical insulation properties; they have the physicochemical properties of fire resistance, good acid-soluble, low cation exchange capacity.So kaolin has become essential raw materials in dozens of industries ,such as papermaking, ceramics, rubber, chemicals, paints, pharmaceuticals and defense .especially,they are widely applying to the process of packing in the paper industry and the coating process in the surface pigment.
The processing technology of kaolin:
particle size distribution means the percentage of the natural kaolin particles in a given type of continuous grain size (in millimeters or micrometers mesh sieve means) within the range of the proportion (expressed as percentages). Particle size distribution of kaolin is very important for the optionality of ores and the applications of processing.The particle size have a significant impact on its plasticity, mud viscosity, ion exchange capacity, formability, drying properties, and firing properties. Kaolin ores also require processing .The possibility of whether ores can be processed to the required fineness easily, has become one of the criteria for evaluating the quality of the ore. for different kaolin ,Various industrial sectors have their own specific particle size and fineness requirements. Shanghai Xuanshi kaolin processing milling equipment ,base on characteristics of kaolin, equip with the features of good regulation performance and automatical control;they are reliable,full of security and stability; and the closed structure can prevent dust pollution effectively.with less mechanical wear,they operator with the advantages of energy conservation and less noise.
Application of kaolin:
At present,kaolin has been widely applied to industries fields such as ceramics, rubber, plastics, leather, cement, refractories, chemical , as well as to agriculture.With further improvement of kaolin beneficiation process, range of kaolin’s applications will become increasingly extend.With the development of national economy, there is growing emphasis on deep processing of kaolin, because it not only provides new materials with special properties, but also improves economic efficiency. One of kaolin processing methods,is heat the kaolin which has been washed and l dried,through roasting, dehydration, turning it into meta-kaolin .it can be used as filler for plastic cable which can improve the cable sheath insulation performance. Commonly, Rubber footwear fillers are mainly two types: organic fillers and inorganic fillers.The former includes recycled rubber and recycled materials, and the latter contains silica, kaolin, titanium dioxide, magnesium carbonate, magnesium oxide, carbon black and zinc oxygen powder.Kaolin is a new type of rubber filler which has been developed in recent years. However, all applications of kaolin must be processed into powder, than adding to other materials till fully integrated.
