Performance equation mcivor et al., 1990, the absence of a performance parameter to isolate ball mill grinding efficiency handicapped efforts to study the effect of any ball mill design or operating variable.Along with plant testing difficulties, only fairly large changes in circuit performance could be linked to a media size change.
Seen, the vertical mill consistently presented lower net specific energy consumption than the ball mills which operate on the same circuit.The averages were 11.3, 11.7 and 6.5 kwht respectively for ball mill 01, ball mill 02 and vertical mill.Figure 5 net specific energy consumption of regrinding circuit.
Equation for ball mill circuits.Define and calculate the classification system efficiency of a ball mill circuit.Define and calculate the grinding efficiency of the ball mill in a ball mill circuit.Relate overall ball mill circuit output and circuit efficiency to specific design and operating variables.
To determine the power that a dry grinding needs, full grate discharge mill equation 1 is multiplied by the factor of 1.08.A multicompartment 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.
This equation is often used to determine the amount of water in a process stream1 knowing the solids concentration by weight and the tonshr of solids in a process stream.Solids concentration example.The underflow stream from the classifying cyclone bank contains 100 tonshour of ore which represents 45 of the total slurry mass.
Table i shows the bond ball mill work index obtained for the ore samples as well as the iron and silica content in concentrate and tail after lims.The concentrate weight recovery was in the order of 5060.Furthermore it may be observed that the bond ball mill work indices for the ore wi varies from 14.6 to 20.9 kwht.
Equation 1 to drive the corrected power requirement rowland, 1982.The equation for third theory of comminution bonds was originally developed for use with conventional crushing and grinding circuits crusherrodball mill or crusherball mill.By the 1970s, the application of conventional tended to be limited to relatively low capacities.
