Ball Mill Design/Sizing Calculator; The power required to grind a material from a given feed size to a given product size can be estimated by using the following equation: where: W = power consumption expressed in kWh/short to Wi = work index, which is a factor relative to the kwh/short ton required to ...
Grinding mill machine for calcium carbnate powder products . GYM 168. 1. This Equipment installed capacity is 245KW and the power consumption is about 90 KW.H per hour. The power consumption is lowest if compared with the .
W is the work index measured in a laboratory ball mill SAG mills use a ball charge of 8 to 21%. formula for calculation of degree of filling in ball mill
Net power draw for an industrial mill is calculated by one of the methods as : N = k x F x n x µ x D x a Where, N = Net power k = Constant for unit conversion F = Quantity ball charge, and mill filling about 28 35% of available millvolume n = Mill rotation, 12.
Equation 1 is multiplied by the factor of 1.08. A multi compartment ball mill consists of two or more grate discharge ball mills in series. The same equation is used to calculate the power that each ball mill compartment should draw. The total power is the sum of the power calculated for each of the separate compartments.
I would like to know if anybody knows the power consuption in KW per ton of a ball mill milling cement clinker at a feed of 1quot; minus in order to produce Portland Cement. I would also like to get the same info for a roller mill.
