The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force. At a certain height, it will automatically fall and impact ...
The working of a grinding machine: A grinder features an electric motor that supplies motion power to the grinding wheel using a pulley and belt. For the portable grinder, the rotor is inside the grinding machine, and the power switch is located beside the handle of the grinder. So, the switch must be pressed before the grinder works.
A feature of ball mills is their high specific energy consumption; a mill filled with balls, working idle, consumes approximately as much energy as at fullscale capacity, during grinding of material. Therefore, it is most disadvantageous to use a ball mill at less than full capacity. Ball mills have the following advantages:
