The ball mill is a hollow drum closed with loading and unloading end caps, filled with grinding media and rotated around its axis.The drum of the ball mill (Pic. 1) is a hollow cylinder of steel, lined inside with armor lining plates which protect it from impact and friction effects of the balls and the grinding material.
Super Orion S.O. Ball mill for the dry comminution of hard materials, especially for the ultrafine range < 10 µm in circuit with an Alpine ultrafine classifier. Grinding drum lined with tungsten carbide wear plates or with silex or ceramic elements when the requirement is grinding without iron contamination.
Vertical roller mills also occupy less floor space than ball mills. But despite these advantages, vertical roller mills are prone to premature bearing failures due to dust contamination. On average, cement mills have to change these bearings every 8 months to avoid failures, even though the calculated bearing life is much longer.
