Abstract
The G-M-H size distribution function contains three parameters and can describe the major features of size distribution used today.
The authors apply this equation to batch ball mill grinding process and study the subject from some angles of the comminution kinetics.
By using the Lewis' equation, comminution energy is represented in terms of a parameter of the Lewis' equation and those of the G-M-H function.
From the above result, size distributions of the batch ball mill grinding product is represented by the following equation. y={1-(x/x0)α}C1tm……(25) where E1 and m are defined by parameters of the G-M-H function and that of the Lewis' equation.
Kinetics of disappearance of feed size is studied by using eq. (25).
This equation is also derived as an analytical solution of the mass balance equation where some assumptions are made about the breakage function and the selection function.
Eq. (25) is confirmed experimentally and a practical application of this equation is tried. A method for determining three parameters of the G-M-H distribution function is also shown.
