mill discharge product size in relation to the lifting effect of the liners. In this specific case, it is obvious that a certain load expansion is needed to allow the coarse particles entering the media charge to be reduced. Therefore, at this stage, a direct measurement of the dynamics in the mill gives very valuable information to the operator.

Load Calculation For Each Tributary Area A= 40sqft x 50psf or 2000 lbs B= 19.5sqft x 50 psf or 975 lbs C= 21 sqft x 50 psf or 1050 lbs D= 19.5sqft x 50 psf or 975 lbs Notice that the middle tributary zone must carry more weight than the adjacent areas B and D.

The load factor can be used to calculate the weight of the material per cubic metre/yard from bank to loose state. Multiply the bank weight by the load factor to get loose weight. Example: Basalt has a bank mass density of 4950 lb/yd3 with a swell percentage of 67% A swell of 67% has a swell factor of 1.67 and a load factor of 0.599

These calculations are based upon theoretical values and are only intended for planning purposes; not precise projections of cutting forces. Actual results will vary.
