Gaoling rock is a very important non-metallic mineral. The kaolin produced by crushing, grinding and calcination has a series of excellent properties, and has been widely used in many industries, especially in the coating industry. At present, the price of ordinary calcined kaolin products is low, but its covering power is not ideal, which limits its application in the field of high-grade coatings. The is shown that with the increase of particle size, the covering force of calcined kaolin is gradually increased, the main reason is that the finer the kaolin particles, the greater the covering force. Kaolin grinding is a production equipment used for processing 300-1250 ultra fine kaolin to improve its covering power. What are its advantages? Today by kaolin mill manufacturer Guilin Hongcheng  for you a detailed introduction.

After crushing, grinding and superrefining, 850℃ calcination, which provides a practical reference for the application and deep processing of coal system kaolin. Due to its high content of silicon and aluminum, kaolin is fragile and difficult to wear. It is required to be relatively fine (325 mesh sieve 5%~10%), and ordinary Raymond mill can not achieve a high yield on the basis of this fineness.
