Do you need a quick estimation of a ball mill’s capacity or a simple method to estimate how much can a ball mill of a given size diameterlenght grind for tonnage a product P80 size Use these 2 tables to get you close No BWi Bond Work Index required here BUT be aware it is only a crude approximation for “most soft ores” from F80 1 cm to P80 700um
Ball Mill Power Calculation Example 1 A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80 passing ¼ inch 6350 microns The required product size distribution is to be 80 passing 100 mesh 149 microns
Based on his work this formula can be derived for ball diameter sizing and selection Dm 6 log dk d05 where Dm the diameter of the singlesized balls in mmd the diameter of the largest chunks of ore in the mill feed in mm
Please find below two calculators for sizing mills using the Bond and Rowland methods Ball mill sizing Calculator for ball mills in a single stage circuit Rod ball mill sizing Calculator for rod mills as first stage of the circuit and ball mills as second stage of the circuit
A Total Apparent Volumetric Charge Filling – including balls and excess slurry on top of the ball charge plus the interstitial voids in between the balls – expressed as a percentage of the net internal mill volume inside liners B Overflow Discharge Mills operating at low ball fillings – slurry may accumulate on top of the ball charge causing the Total Charge Filling Level to be
simple calculation in the ball mill – Grinding Mill China Simple Torque Calculation for Belt Conveyor Hello Simhup If I ever need to calculate approximate conveyor power for example on simple inplant inclined conveyors I often do the following simple calculation Power th x lift x 272 x 13 kW From this you can easily calculate the
the optimum composition of the make up ball sizes in ball mills is presented an equation therefore could be developed for calculating the optimum into a grinding model and investigate the effect of the make up ball size on the mill the breakage of a uniformly sized particle results in
Mill Speed Critical Speed Mill Speed No matter how large or small a mill ball mill ceramic lined mill pebble mill jar mill or laboratory jar rolling mill its rotational speed is important to proper and efficient mill operation Too low a speed and little energy is imparted on the product
