Nov 18 2008 Basic principle Ball mill is generally used to grind material 14 inch and finer down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills they must be operated in a closed system. There is a specific operating speed for most efficient grinding.
Nov 30 2015 PRINCIPLE A 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. 7. CONSTRUCTION Wet or dry ball mill grinding machine consists of following parts 1. Feeding part 2. Discharging part 3. Turning and driving part gear motor etc 4. Rotating balls 8.
When the ball mill cylinder rotates the grinding body acts on the cylinder liner due to the action of inertia and centrifugal force and friction. It is carried away by the cylinder. When it is brought to a certain height it is thrown off due to its own gravity. The falling abrasive body crushes the material in the cylinder like a projectile. 3.The material is uniformly fed into the first chamber of the mill by the feeding device
