Rod Mills may be considered either fine crushers or coarse grinding equipment. They are capable of taking as large as 2″ feed and making a product as fine as 3548 mesh. Of particular advantage is their adaptability to handling wet sticky ores, which normally would cause difficulty in crushing operations.

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.

With such laying out of the balls of the same diameter, the volume is distributed as follows: 52% goes to grinding balls, 48% is a void volume. That means, to achieve maximum grinding fineness, it is necessary to charge balls of different diameters. This will result in a decrease of dead volume between the grinding media.

Once a void marker peak is injected, you can use the following formula to determine column void volume: Retention time of void peak (V) * Flow Rate. Example: If an acetone peak retains at min, and the flow rate is mL/min, then: = min * mL/min. = mL. Also see > How do I calculate the empty column volume of a column?
