Working Principle & Operation. The apparent difference in capacities between grindingmills(listed as being the same size) is due to the fact that there is no uniform method of designating the size of amill, for example: a 5′ x 5′Ball Millhas a working diameter of 5′ inside the liners and has 20 per cent more capacity than all otherball millsdesignated as 5′ x 5′ where the ...

In Grinding, selecting (calculate) the correct or optimumballsize that allows for the best and optimum/ideal or target grind size to be achieved by yourball millis an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, theballused inball millsis oversize “just in case”. Well, this safety factor can cost you much in recovery and/ormillliner wear and ...

Fig. 8 shows the optimum compositionof the make-up ball sizesfor various feed sizes as a function of the size reduction ratio, R. Because mixtures of two balls (50.8 mm and 25.4 mmball) are always found to be optimum, the results are plotted with the ordinate being the fraction of 50.8 mm balls.

The feed can be dry, with less than 3% moisture to minimizeballcoating, or slurry containing 20–40% water byweight.Ball millsare employed in either primary or secondary grinding applications. In primary applications, they receive their feed from crushers, and in secondary applications, they receive their feed from rodmills, AGmills, or ...

Mar 10, 2011· Re: How Can I calculate newball size and weight desing for ball mill. Dear Khan, According to my point of view:-1.Firstly look for the performance of roller press product then go for the mono chamber. 2.Is the roller press with the separator or not? 3.Mono chambermilltotally depend on the performance of the prigrinder.

Themillproduct can either be finished size ready for processing, or an intermediate size ready for final grinding in a rodmill,ball millor pebblemill. AG/SAGmillscan accomplish the same size reduction work as two or three stages of crushing andscreening, a rodmill, and some or all of the work of aball mill.

Ball Mills- Mineral Processing Metallurgy. However, it is now commonly agreed and accepted that the work done by anyball milldepends directly upon the power input; the maximum power input into anyballor rodmilldepends uponweightof grinding charge,millspeed, and liner design.
