Nov 18 2008 its value ranges from 09 to 14 42 the speed of the shell the maximum speed avoiding centrifugal force where 43 mass of balls the bulk volume of the balls is 3045 of the volume of the shell of the ball mill and the feed is filling the empty space between the balls where the static porosity is about 40and the balls charge is vary from 3045 5
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 1050 rpm
The rotation speed is a key point related to the ball mill efficiency rotation speed too great or too small neither bring good grinding result based on experience the rotat ion is usually set between 420minute if the speed too great may create centrifuge force thus the grinding balls stay with the mill
This is a 3foot by 6foot continuous ball mill and this machine will process one ton an hour at 65 mesh you can actually process finer than that down to about 200 mesh but the throughput goes down to the feed side you can put three quarter to one inch minus here then ore enters into the scoop of ball mill with a twoton charge of balls
