MILL DESIGN & MILL OPERATION

NORMAL MILL PRACTICES Not to monitor lift of top roller It is assumed that top roller lifts only that value considered during mill setting calculations Normally actual lift of top roller during operation is higher than considered in mill setting calculation Higher thickness of cane/bagasse blanket passes through mills due to excessive lift of top roller

AG - Autogenous & SAG Semi-Autogenous Mill Design Calculations

This charge weight is usually calculated for the percent filling determined from the performance of the pilot plant tests and by the design of the feed end of the mill. Generally some user-specified safety factor is provided above the normal operating conditions such as actually designing for a 35% volume rather than 30%.

Ball Mill Design/Power Calculation

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 …

Common & Basic Formulas for Mineral Processing Calculations

Formula (32) is very convenient for milling calculations on ores of this type. Example: An ore contains 5% lead and 1% copper. The ratio of perfect concentration for a concentrate of maximum grade and recoveries of lead and copper would be: by (29) K perfect = 100/5.775+2.887 = 11.545 and % Pb in perfect concentrate = 11.545 x 5 = 57.7%
