Heavy calcium is the abbreviation of heavy calcium carbonate, and heavy calcium carbonate is also calcite. According to statistics, there are three main types of calcium carbonate deposits in my country: limestone, chalk and marble, which are widely distributed in the crust. Therefore, it is very necessary to carry out research on calcium carbonate processing technology and develop deep-processed products. Calcium carbonate has been widely used in chemical, paper, building materials and other industries. The requirements for heavy calcium in these industries are trending towards ultra-fine and ultra-white, especially for applications in the paper industry. In recent years, a lot of work has been done on the purity, whiteness and fineness of calcium carbonate, and great progress has been made. 1. Heavy calcium deep processing and ultra-fine technology For calcium carbonate with lower purity, the process of purification and impurity removal is generally used to improve the purity and whiteness. Most of the calcium carbonate minerals in our country have a purity of more than 98% and a whiteness of more than 90%, which do not require purification, but only need to be ground.

Heavy calcium powder ultrafine grinding processing method and process

Heavy calcium powder is mainly obtained from calcite processing. At present, vertical mill is mainly selected as the main equipment for calcite grinding in industry. (coarse crushing) – impact crusher (fine crushing) crusher crushing – elevator to silo – mill grinding – conveyor to silo – superfine mill – dust removal – packaging.

Our company specializes in R&D and manufacture of crushers, sand making machines and grinding mills. Its calcite grinding mill (heavy calcium grinding mill) is a domestic special heavy calcium milling equipment. The manufacturer is also the supplier of ultra-fine grinding mills in East China. After its calcite is processed by our company’s professionally built mill grinding equipment, the white powder produced is heavy calcium carbonate, referred to as heavy calcium. Heavy calcium powder has the characteristics of high whiteness, good purity, soft color and stable chemical composition. , food, medicine, textile, feed, toothpaste and other daily chemical industries.
