ball grinding volume

Ball mills tumble iron or steel balls with the ore The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds The feed to ball mills dry basis is typically 75 vol ore and 25 steel The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones

The principle of rotary ball mills is that energy is transferred from outside drive by a So in theory the size of the used grinding media balls does not have Each smaller the balls each closer is the contact area to an idealised punctual shape and so each higher is the deformation energy per volume of grinding

Jul 1 2003 Grinding is directly related to energy absorbed in the mill chamber The nominal energy density of a mill is the available energy per volume of milling chamber The specific energy for each experiment was calculated and plotted a Stirred Ball Mill and Their Effect on Comminution DRAIS News Vol Get price

Ball Mill Volume Calculation A grinding circuit simulation combined with ball weal law was used to determine the optimum composition of the makeup ball sizes in tumbling ball mills It was found that the optimum composition depends on various factors including the feed size the product size the mill

Volume Ratio Of Grinding Ball In Ball Mill volume ratio of grinding ball in ball mill The ballmill circuit was sampled and operating model parameters were calculated to determine model parameters for ballmill grinding of the ore A sampling volume ratio to 120 and the sample was wetground for 3 min The mill was Get Price Read More

Diameter – depending on the material ranging from 005 mm to 2 mm for small media mills up to 18” to 1” for traditional Attritors and up to ½” to 2” for ball mills Composition – metallic grinding media like carbon steel forged steel stainless steel or chrome steel grinding

Also with low ball charge slurry pool will reduce grinding efficiency Beside lower ball charge will increase P80 of ball mill because of less number of impacts but mean residence time will increase by lower ball charge because of more volume to occupy I think at
