Typical size of ball mill ball mills steel ball mills lined ball mills particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800s the basic construction of a ball mill is a cylindrical container with
Get PriceTypical loads for ball mills the ball mill has higher circulation load it generates only30 35 of actual fines you require to be called as product if your product size needed is 100 passing45 micron then the ball mill total discharge material will contain normally 30 of45 micron the rest is oversize which has to be ground again
Get PriceAn industrial test work was performed to analyse the effect of applying a lower ball load and a finer ball size distribution in the second compartment of a khd humboldt wedag ball mill on grinding and classification performance of a hybrid high pressure grinding roll hpgrmulticompartment ball mill cement grinding circuit mass balance of the circuit was done by jksimmet steady state
Get PriceBall mills are generally used to grind material 14 inch and finer down to the particle size of 20 to 75 microns to achieve a reasonable efficiency with ball mills they must be operated in a closed system with oversize material continuously being recirculated back into the mill to be reduced
Get PriceSep 01 2013 fig 6 shows one set of results where the circuit capacities are shown in threeballsize ternary diagrams for various feed sizes with a circulation ratio of 25 at a size reduction ratio of 451 using a 1 m diameter ball mill it can be seen that maximum contour lines stay in the bottom of the diagrams for all cases indicating that
Get PriceOne 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 an empirical model from emerging trends in mineral processing 2005 is

Get PricePlanetary ball mills are used wherever the highest degree of fineness is required in addition to wellproven mixing and size reduction processes these mills also meet all technical requirements for colloidal grinding and provide the energy input necessary for mechanical alloying
Get PriceWorking principle operation the apparent difference in capacities between grinding mills listed as being the same size is due to the fact that there is no uniform method of designating the size of a mill for example a 5 x 5 ball mill has a working diameter of 5 inside the liners and has 20 per cent more capacity than all other ball mills designated as 5 x 5 where the
Get PriceIf a ball mill uses water during grinding it is a wet mill a typical ball mill will have a drum length that is 1 or 15 times the drum diameter ball mills with a drum length to diameter ratio greater than 15 are referred to as tube mills ball mills may be primary or secondary grinders primary grinders are fed from crushers such as a
