Grinding Surface Area Ball Rod

In addition, the surface area per unit volume of the steel bar medium is smaller than that of the steel ball medium, so the utilization coefficient of the rod mill is lower than that of the same simplified diameter ball mill, and it is not suitable for fine grinding equipment.

  • Technical Performance And Application Of Ball Mill And Rod

    Ball Mill Size as a Replacement. Grinding media wears and reduces in size at a rate dependent on the surface hardness, density and composition of the ore. Ball wear is directly proportional to surface area per unit mass and thus inversely proportional to ball diameter. Other factors include Speed of mill rotation Mill diameter Mineral density.Tapered cylindrical grinding media with rounded edges and equal length and diameter with sizes varying from 8 8 to 45 45 mm. Their shape is developed to maximize the grinding efficiency due to their high density and specific surface area [17]. Ceramic balls with regular density are usually porcelain balls.

    Oct 12, 2017 Ball mill is a fine grinder. A horizontal or vertical rotating cylinder which is filled partially with the balls of ceramics, small rocks and balls made from stainless steel. The ball charge of a SAG mill is about 29 to 30 . By friction and influence of tumbling balls inside rotating cylinder grinds the raw material to the required fineness.Apr 09, 2015 Ball mill (Fig 1) is same kind of mill as rod mill, except that it is filled with balls instead of rods. Because of balls have greater ratio of surface area than rods they are suitable for fine grinding. Balls are also lighter, so the kinetic energy of a single dropping ball is smaller than a rod.
