magnetic separator price

The main minerals of kaolin are kaolinite and polyaqueous kaolinite. In addition to kaolinite minerals, it is often accompanied by clay minerals such as montmorillonite, illite, phyllachite, quartz, feldspar, iron minerals, titanium minerals and other non-clay minerals and organic matter. To produce Kaolin products that can meet the needs of various industrial fields, the PTMS magnetic separator of kaolin is often purified by physical method, chemical method and high temperature calcination method.

PTMS magnetic separation

 
Physical purification method mainly uses the differences in particle size, density, magnetic and surface adsorption physical properties of different minerals to separate some non-clay minerals, including hand separation method, water separation method, flotation method, magnetic separation. Chemical purification and bleaching are mainly used to remove iron minerals in kaolin by PTMS magnetic separator. The main methods include acid leaching, chlorination, alkali treatment, reduction, oxidation and REDOX combined process.

what is magnetic separation？

 
High temperature calcination is the best method to remove carbon and enhance whitening. It is also a necessary method to process the PTMS magnetic separator of kaolin in coal measure strata. Usually calcined at 650 ~ 1050℃, so that kaolin phase completely changed, while some impurities volatilized, to improve the whiteness and insulation effect. Sometimes, chlorination roasting, oxidation roasting and other high temperature treatment methods can be used to remove iron and titanium elements in kaolin.
