Get PriceA ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis the balls which could be of different diameter occupy 30 50 of the mill volume and its size depends on the feed and mill size
Get PriceMar 14 2017 in the grinding material process at ball mills becomes necessary to calculate the bulk weigh of used grinding media the bulk weigh of the grinding balls is necessary to understand the grinding balls mass in the cube the grinding balls mass loaded into the mill the prevention of mill overloading with grinding balls etc these data often used in operational management of grinding
Get PriceIn ball milling the desired particle size is achieved by controlling the time applied energy and the size and density of the grinding media the optimal milling occurs at a critical speed ball mills can operate in either a wet or dry state

Get PriceThe sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience different manufacturers use different methods and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent it is especially difficult to teach mill
Get PriceUsually plant operators use mill power readings as an indicator of ball filling degree and often try to keep it at the maximum level it is well known that the mill absorbed power depends on operating parameters other than ball level such as pulp density and liner configuration figure 2 shows that there is no linear relation between
Get PriceThe density of the charge must account for all of the material in the mill including the media which may be steel balls in a ball mill or large lumps of ore in an autogenous mill or a mixture in a semiautogenous mill as well as the slurry that makes up the operating charge let jt be the fraction of the mill volume that is occupied
Get PriceMill weight during the test from the empty mill weight including the ball charge at the start of the test the pulp volume of the pulp in the mill is then calculated using the mill discharge density before dilution obtained during the sampling the ball charge and hence the volume of the voids
