A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders. Primary grinders are fed from crushers such as a jaw crusher.
Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters Morrell 1996. Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding the ratio could vary between 1:1and 1.8:1.
Calculate and Select Ball Mill Ball Size for . Calculate and Select Ball Mill Ball Size for Optimum Grinding. Based on his work this formula can be derived for ball diameter sizing and selection: Dm . 6 log dk d0.5 where D m the diameter of the single-sized balls in mm.d the diameter of the largest chunks of ore in the mill feed in mm.
Calculate and Select Ball Mill Ball Size for Optimum Grinding. In his paper The Preferred Size of Balls for Ball ... the correct or optimum ball size that allows for the best and optimumideal or target grind size to be achieved by your ball mill is an Contact Supplier
Determination of optimal ball size distribution as a function of size distribution of mono-mineral raw material quartz. Investigations have been performed in laboratory ball mill with the following characteristics: Mill diameter D 158 mm; Mill length L 198 mm; Relative mill revolution rate Ψ 0.85nk; Ball mill filling
Don't know about the roller but the optimum speed for a ball mill depends on the size of the jar and media. There's a formula for calculating this I don't have it around but it is in Lloyds book. However for a 6 jar and 34 media it should be appr. 75RPM. It decreases with jar size and increases slightly with media size.--
