Working Principle Operation. The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where the ...
Mill (grinding) Wikipedia. Operation of a ball mill. Ball mill. A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls.
During operation, the ball load can be monitored by monitoring the main motor current of the ball mill. If the current is found to drop significantly, the steel balls need to be replenished in time. The ball mass ratio should be designed according to the design when the ball mill is put into operation for the first time.
