Ball Tube Mills

Aerated ball tube mills are designed for anthracites, coal, lignite, shale and other materials grinding up to pulverized condition and for continuous operation in coal pulverization systems at thermal power plants and other branches of industry. the coal grinding process in aerated mills is performed simultaneously with coal drying inside the drum. coal together with drying agent is fed into the drum through the coal feeding branch pipe, and finished pulverized coal.
