WhatsApp: +86 18203695377The four most common types of coal pulverizers are: BallTube Mills This type of mill consists of a rotating tube filled with cast alloy balls. Coal is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the coal,crushing and pulverizing it.
WhatsApp: +86 18203695377Ball mills are the most common type of coal grinding mill, and are characterized by their simple design and low maintenance requirements. They use steel balls to crush and grind the coal material, which is then discharged through a screen to separate the fine particles from the coarse ones.
