Get Latest PriceBall mills tumble iron or steel balls with the ore the balls are initially 510 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
More DetailsBall mill the inner surface of the cylindrical shell is usually lined with an abrasionresistant material such as manganese steel or rubber less wear takes place in rubber lined mills the length of the mill is approximately equal to its diameter
More DetailsMore balls with small size results in fine powder as a thumb rule powder to be milled should be taken as 25 of total ball weight if the quantity of charge is very less then milling balls will
More DetailsAbstract the specific rates of breakage of particles in a tumbling ball mill are described by the equation si axi q z where q z is the probability function which ranges from 1 to 0 as particle size increases this equation produces a maximum in s and the particle size of the maximum is related to ball diameter by xm k1d2
More DetailsJun 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 pregrinding operation
More DetailsBallrod mill literature the ballrod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size level they are the most effective laboratory mills for batchwise rapid grinding of mediumhard to very hard samples down to finest particle sizes
More DetailsThe high energy ball mill emax combines highfrequency impact intensive friction and controlled circular jar movements to a unique and highly effective size reduction mechanism the grinding jars have an oval shape and are mounted on two discs respectively which move the jars on a circular course without changing their orientation
More DetailsThe drum i used for the ball mill was originally a plastic container that held abrasive grit used in vibratory tumblers it is about two liters in size i had several empty containers of this type and decided to put them to use in this project they work pretty well in this application
More DetailsFeed size vs ball size 7 replies one can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum then the multiple would be closer to 13 times the maximum particle size fed to the ball mill a f80 6 mm would need a ball size of 75 mm
More DetailsBall size depends on initial size of charge and ranges from 10mm150mm dia for particular material and initial size the ball size must be optimized please refer the link below and see if it works for you and other method is hit and trial the ball size to be decided based on the impact energy requirement
