To match a ball mill size and its motor size, some math is required The power requirement calculated above is the motor power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution The following shows how the size of mill required to draw this power is calculated
Ball mills are filled up to 40% with steel balls , the power input and capacity of pebble mills are correspondingly lower Thus, in a given grinding circuit, for a certain feed rate, a pebble mill would be much larger than a ball mill, with correspondingly a higher capital cost However, the increase in capital cost is justified economically .
Small media has a larger surface area which translates to better transfer of energy Although Tower Mills are full attrition grinding, they are constrained to using relatively coarse media 12-25mm balls In contrast the IsaMill™ can operate with much finer media (eg 1mm) and much higher intensity of power input
