Jun 25, 2018· Mill effective diameter = 223 m 335 is a constant used for dry grinding with steel balls in the mill Actual size of media is taken is lower than the calculated value It is around 80 to 90 mm If you Wants to reduce the maximum ball size, thenreduce the feed size by using pre-grinding operation

Ball mills are filled up to 40% with steel balls (with 30–80 mm diameter), which effectively grind the ore The material that is to be ground fills the voids between the balls The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fracture

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 .
