ball mill grinding ball charger. Ball Charger Grinding Ball Charger Grinding The ball charge is determined by the operator targeting the balance between grind and throughput the higher the ball charge the more aggressive the milling becomes With softer oxide ores lower ball charges are usual however the harder sulphides does need more media energies to meet the P80 target and an
Nov 29 2018 Medium charge ratio of ball mill and rod mill. Medium charge ratio is the percentage of grinding medium in the volume of the grinder. For different grinding methods there is a suitable range in grinder structure operating condition medium shape and medium charge ratio. Too high or too low medium charge ratio will affect the grinding effect.
calculating steel ball charge in ball mill. Ball mill consist of a hollow cylindrical shell rotating about its axis. Axis of the shell horizontal or at small angle to the horizontal It is partially filled with balls made up of SteelStainless steel or rubber Inner surface of the shell is lined with abrasion resistant materials such as ManganeseSteel or rubber Length of the mill is .

Jun 19 2015 We can calculate the steel charge volume of a ball or rod mill and express it as the of the volume within the liners that is filled with grinding media. While the mill is stopped the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The loading or change volume can then be read off the graph below
The starting point for ball mill media and solids charging generally starts as follows 50 media charge Assuming 26 void space between spherical balls non-spherical irregularly shaped and mixed-size media will increase or decrease the free space 50 x 26 13 free space Add to this another 10-15 above the ball charge for total of 23 to 25 product loading.
