WhatsApp: +86 18203695377The ball mill is a traditional coal pulverizer machine, which has been widely used since it was invented. In the cement plant, the new dry process cement manufacturing requires the moisture content of coal powder to be % ~ %, while that of raw coal is % ~ %. Therefore, the ball mill should have a drying function besides grinding.
