The Problem with Chromite Processing Experience indicates that chrome ores are concentrated to best advantage by gravity methods. Since recoveries are generally very poor in the fine sizes, the gravity flowsheet must be designed to remove the chrome as soon as liberated by crushing and grinding. For example, if the chrome is not entirely …

Ball mills are used to obtain a product size below 150 microns. With the rotation of the mill, collision and attrition forces grind down the material in the mill chamber. The balls act as the grinding media, where contact points are created with each other and the material is either crushed or ground.
Wet disc mills generally have simpler mechanical structures and fewer moving parts than traditional ball mills, which can mean lower downtime and operating costs. 3. Abrasiveness. Harder materials may wear out the ball mill more quickly than a sturdier designed wet disc mill, requiring more frequent grinding media changes.
