dec 16, 2019 dec 16, 2019 so kaolin has become papermaking, ceramics, rubber, chemicals, paints, pharmaceuticals and defense industries and dozens of mineral raw materials necessary. kaolin application paper industry is very extensive. there are two main areas, one of the filler used in the papermaking process, and the other is a pigment used in the surface coating process.

New generation calcium carbonate | 20 microns

Paper : calcium carbonate is used in paper mill as a filler material in the alkaline papermaking process. now a days calcium carbonate dominant over other papermaking filler materials; though at the first stage of papermaking kaolin was 1st choice. the main reason behind the preference of calcium carbonate is the demand for brighter and bulkier

apr 04, 2021 apr 04, 2021 kaolin is a silicate mineral. due to its water-containing silicate chemical composition and layered structure characteristics, it has special properties that many half of the minerals do not possess. kaolin is mainly used in papermaking, ceramics and refractory materials, followed by coatings, rubber fillers, enamel glazes and white cement raw materials, and a small amount application

small ultrafine mill, essential equipment for chemical production; s-series ultrafine mill has become the most ‘killer’ in high quality kaolin paper making; ultrafine mill has become the most popular equipment for highway construction in sudan; knowing the ultrafine mill better, using it better develop the understanding of the working principl
