Kaolin Milling to 300mesh: Ultra-fine Milling Equipment and Product Quality Control
Kaolin is a kind of non-metallic mineral with excellent physical and chemical properties, such as good plasticity, high whiteness and strong adsorption. It is widely used in papermaking, ceramics, coatings, rubber and other fields. The fineness of kaolin powder is an important index affecting its application effect. 300mesh kaolin powder has fine particle size and uniform distribution, which can improve the performance of products. Therefore, the ultra-fine milling of kaolin to 300mesh is an important link in the kaolin deep processing industry.
The ultra-fine ball mill and ultra-fine vertical roller mill are the main equipment for kaolin milling to 300mesh. Kaolin has the characteristics of low hardness and good grindability, so the selection of milling equipment should focus on product quality and production efficiency.
Ultra-fine ball mill is improved on the basis of traditional ball mill, which has the advantages of simple structure, reliable operation and good grinding effect. The ultra-fine ball mill is equipped with a high-efficiency classifier, which can accurately control the fineness of the powder. When milling kaolin to 300mesh, the raw kaolin is first crushed to less than 20mm by a crusher, and then sent to the ultra-fine ball mill.
The grinding media in the mill are small-diameter steel balls or ceramic balls, which can fully grind the kaolin. The ground material is sent to the classifier for classification, and the 300mesh qualified powder is collected by the dust collector. The ultra-fine ball mill has the advantages of stable product quality and strong adaptability to materials, but its energy consumption is relatively high.
