  • How to design a Ball Mill Grinding & Classification

    You also need a rod mill work index to design a ball mill operating on a coarse feed, above about 4 mm Q1: You design for a typical percentage of critical speed, usually 75% of critical Then you iterate the mill diameter using a Morrell Cmodel or equation to get the RPM that corresponds to 75% for that mill diameter Q2: You first work out the specific energy consumption using the· The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closedBall Mill Design/Power CalculationBall mills are simple in design, consisting of horizontal slow rotating vessels half filled with grinding media of ¼” to 15” The particles to be milled are trapped between the grinding media or balls and are reduced in size by the actions of impact and attrition Ball mills have the advantage of being selfcontained so operators are not exposed to the product being milled Ball millsBall Mill Application and Design Paul O Abbe
