### Operating Procedure for Ball miller

(16) After completing the experiment, turn off the ball miller by following the same procedure for turning it on. Warning: The manufacturer warns against un-attended operation. Someone should be in the room to turn it off if it overheats or fly-s apart. There is a mechanical danger

More### The operating principle of the ball mill

The disadvantages of ball mills include their considerable metal consumption and deterioration grinding media, as well as a lot of noise. Most of the energy useless lost during ball mill operation, leading to low it efficiency. But even a significant specific energy consumption for grinding material compensates beneficial effect by using mill.
