Talc is one of the most commonly used ultrafine powder products in the world. At present, talc powder is mainly processed by dry process, which is rarely used in industry. Dry process production equipment mainly includes high-speed mechanical impact mill, dolomite sand, jet mill, centrifugal self mill, rotary mill, vibration mill, stirring mill and tower mill. In addition to the airflow mill, in order to meet the requirements of particle size distribution, other classification equipment usually need to be equipped with fine classification equipment. The commonly used fine classification equipment is a variety of turbine air centrifugal classifier.

Talc powder is processed by selecting high quality talc powder. Each process is produced according to strict operation specifications and test standards. Talc is the foundation of all chemical industries. Without the support of talc industry, China's chemical industry will stagnate. Therefore, talc production technology level has become an important indicator to measure the level of a country's chemical industry, but also an important part of a country's economic development.

China's talcum powder production country, the rapid growth of China's industrial level, which is closely related to the development of talcum powder industry. In recent years, a large number of competitive enterprises have emerged in China's Talc industry, but the overall level of talc production still lags behind the international advanced level, and the output of talc still can not meet the market demand. The edible talc powder is made from limestone and processed into white powder by lime mill. Its main component is CaCO3. Heavy calcium has the characteristics of high whiteness, good purity, soft hue and stable chemical composition. Heavy calcium is usually used as a filler.
