  • Ball Mill Operating principles components Uses

    Ball Mill Operating principles components Uses,The balls which could be of different diameter occupy 30 50 of the mill volume and its size depends on the feed and mill size The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls Ball mills grind material by impact and attrition

  • How Ball Mill Ore Feed Size Affects Tonnage Capacity

    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

  • Feed Size VS Ball Size Grinding Classification

    Feed Size VS Ball Size Grinding Classification,A ball diameter that grabs the particle must exceed the particle by 25 times to achieve this semiself locking taper 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
