Planetary ball mill is used to determine the dependence of process efficiency using milling parameters such as ball size and number, mill geometry, and velocity of the rotating parts.
High temperature of the ball mill will affact the efficiency. 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% -10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded.
When ball milling, always use about 2/3 balls by volume. Make sure the drum isn't going too fast--say 2 revolutions per second, max. It helps to glue a couple of wooden "paddles" inside the drum to aid mixing. If the drum goes too fast, it will …
Ball mill. A ball mill is a common type of grinding machine. It is a tube that has a flat surface and is capable of holding a lot of rock or metal balls. With the help of the undulating ball, these balls grind material by smashing and abrasion. A ball mill has a narrower width and a shorter span. Its length is between 1.5 and 2.5 times its size.

Schematic drawing of an attrition ball mill. The attrition mill agitator rotates at speeds ranging from 60 rpm for production units to 300 rpm for laboratory units and uses media that range from 3 to 6 mm while ball mills use large grinding media, usually 12 mm or larger, and run at low rotational speeds of 10–50 rpm.

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
The order comprises a 22-foot diameter by 8-foot effective grinding length (egl) SAG mill and 14.5-foot diameter by 19.5-foot effective grinding length ball mill. Both mills will be driven by 2000 ...
