直径和高度相同的圆柱体磨矿介质比钢球生产成本低、经济效益较高。柱形介质能产生点接触、线接触和面接触。因而其产品分布范围较窄,有棒磨机的功效。柱形磨矿介质和同直径、同材料的球型介质相比,其表面积、重量和体积各大50％。若球体和柱体重量相同,则球直径是柱直径的1.145倍、而柱体的比表面积比球体的大14.5％。另外,由于柱体磨矿介质的堆密度是4.9吨/米~3,而球体的是
Cylindrical grinding media of the same diameter and height have lower cost and higher economic benefits than steel balls. Cylindrical media can produce point contact, line contact and surface contact. Therefore, its product distribution of a narrow range, a rod mill effect. Cylindrical grinding media and the same diameter, with the ball of the media compared to its surface area, weight and volume of the major 50%. If the sphere and the column have the same weight, the sphere diameter is 1.145 times the diameter of the column, and the specific surface area of the column is 14.5% larger than the sphere. In addition, due to the bulk density of the cylinder grinding medium is 4.9 tons / m ~ 3, and the ball is
