mill matrix for ball mills

A perfect mixing matrix model for ball mills -

2001-10-1  A comminution model is developed for ball mills using the principles of perfect mixing. T-lines are developed from data arising from single particle breakage tests using a laser monitored, twin pendulum breakage device. A t 1.4 parameter is developed that produces a family t-lines which can be modeled using linear equations.
