4. Sampling inside mill (mill test) Sampling of material. – Take ~1 kg sample every 1 m along mill axis. – Each sample collected from 3 point in the same cross section. – Removed some balls and taken sample. -First and last sample in each compartment should be taken. from 0.5 m off the wall or diaphragms. 4.
Calculation of the power draw of dry multi-compartment ball mills 225 The mill load that is the volume of charge in the mill is the principal determinant of power draw. Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous. So direct measurement must be taken for calculation of mill load.

In Example it was determined that a 1400 HP wet grinding ball mill was required to grind 100 TPH of material with a Bond Work Index of 15 (guess what mineral type it is) from 80 passing ¼ inch to 80 passing 100 mesh in closed circuit.
The charge of grinding media for two-compartment ball mill can be calculated for dry grinding of cement raw mix. The medium-hard raw material for the mill feed has a particle size range of 0.5 to 25 mm. The mill dimensions are: -. Inner diameter of mill = 4.2 m. Length of drum = 15.25–1.0 = 14.25 m.
Bulk density of cement was assumed to be 1.8 ton/m 3 and volume of the void between the balls as 40% in the calculations. Estimated mill hold up values for the mill segments to predict specific discharge and breakage rates are given in Table 7. Download : Download full-size image; Fig. 10.

Balls must be added to maintain the media load and mill power draw. The power draw increases as balls are added and decreases as media wears down: add balls. The main control on the power draw for a BM is the load of grinding media however adding water to the cyclone underflow can also be short term control of BM power.

CALCULATION OF THE POWER DRAW OF DRY MULTI?COMPARTMENT BALL … hammer crusher power calculations ? Grinding Mill China Posted at: August 1, 2012.
To determine the power that a dry grinding needs, full grate discharge mill 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
Having the same length, a two-compartment mill obviates the need for pre-milling and performs similarly or better than a three-compartment mill, depending on the ball sizes used. For a given set of ball sizes, a distribution with uniform mass of balls, as opposed to that with a uniform number of balls, achieves 8% increase in cement specific ...
