In a typical grinding mill application, the grinding media eventually fractures and wears into a fine metallic powder because of the heavy re-circulating load in the mill. Energy is unnecessarily wasted to mill the milling media. As shown in Figure 3, the trunnion magnet is mounted at the ball mill discharge point to replace a trommel screen.
A Grinding Ball Mill is a type of grinder used to grind and blend materials for use in mineral processes. A Grinding Ball mill works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A Grinding Ball mill consists of a hollow cylindrical shell rotating about its axis. The ...
