Transient state analysis by simulation in a closed grinding circuit

Study of the Behavior of Binary Mixture Grinding Using the Fixed-Time Locked - Cycle Tests”.

“…Table (2) Particle size analysis of the ground limestone and quartz final products (-200 µm) at the steady state condition when they ground separately Results of the admixture study from 20% to 80% quartz are listed in Table (3). This table contains the particle size analysis of the product at the steady state condition for the different studied admixtures.…”

“…Fig. (2) represents the effect of the percentage of quartz in the feed on its appearance in the product at the steady-state conditions. From this figure it is clear that, the appearance of quartz increases gradually with a constant slope in the product as its percentage increased in the feed.…”

“…During the past few years, extensive efforts have been directed towards automatic control of grinding circuits to optimize the utilization of comminution energy and the recovery of minerals by minimizing overgrinding [1][2][3]. Testing the response of an industrial scale grinding system to variations in operating variables can be an expensive undertaking.…”
