Many people are under the mistaken impression that the only use for kaolin is in the manufacture of china. This is not true, and its use by the paper industry far exceeds its other uses. However, kaolin still serves as a valuable component in china and other tablewares. Its color, gloss and hardness are ideal characteristics for such products.JEZUltrafine Grinder, Ultrafine Mill For Sale
