Jun 19, 2015 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
Oct 09, 2015 Calculating a grinding circuit’s circulating loads based on Screen Analysis of its slurries.. Compared to %Solids or Density based Circulating load equations, a more precise method of determining grinding circuit tonnages uses the screen size distributions of the pulps instead of the dilution ratios.Pulp samples collected around the ball mill or rod mill and
How to calculate cement ball mill capacity Quora (1) Calculate according to the particle size of the newly generated product, also known as the specific productivity =Efficiency of each machine* (product particle size yield-ore particle size yield)/effective volume of ball mill *100 (2) The size of the ball mill is different, and the particle size of the feed and product is the same
Ball mill capacity calculation rock crusher mill rock ball mill capacity calculation ball mill for gold mining indonesia use wet,dry grinding any one can help me
parts include dead load of the rotator, load produced when the machine performs work, and load produced by transmission of dynamic force. These can theoretically be mathematically calculated, but calculation is difficult in many cases. A method of calculating loads that act upon shafts that convey dynamic force, which is the primary application of

Nov 21, 2018 ball mill power . dear experts. we have a ball mill in combi mode for cement grinding . roller press before the ball mill. the supplier has given 28% grinding media filling, with shaft power 2270 kw only. ball mill size is 4.4*11 m. grinding media size is max 30mm . it is a monochamber mill designed to grind the roller press product
Mar 04, 2006 The sum of resistances = tractive pull. The tractive pull multiplied by the drive pulley radius will give you the load torque. There is no short cut for deciding the load torque. This cannot be calculated from motor side. 5) Having decided the load torque, you can decide the required power at motor shaft, available motor size, gear ratio and so on
Circulating Load Calculation Formula. Feb 21, 2015 For example your ball mill is in closed circuit with a set of cyclones The grinding mill receives crushed ore feed The pulp densities around your cyclone are sampled and known over an 8hour shift, allowing to calculate corresponding to circulating load ratios and circulating load tonnage on tons/day or tons/hour
