Ball Mills - Mine Engineer.Com

Ball Mills are generally used to grind material 1/4 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.

British Cannonball Sizes

The difference in diameter is termed "windage". The final bore diameter and hence the windage of earlier 16th and 17th century guns was a matter for the skill of the gunfounder. A value of 0.2 to 0.25 inches was typical. Albert Borgard specified that along with the weight of cannonballs the windage of the guns should be standardised.

How Ball Mill Ore Feed Size Affects Tonnage & Capacity

The important of crushing your ore and rock fine and properly is often forgotten. The finer you crush, the higher your ball mill tonnage and capacity will be. The effect of ball mill feed size and how it affects circuit throughput can be hard to estimate. Here we described a method of designing a crushing plant using power drawn and power rate to define reduction ratios in each stage of crushing.
