If you maintain a high ball charge with low tonnage, you'll overgrind. So you can low the ball charge, these means less interaction mineral particle with steel balls so reduce grinding, but also it means that you bed density will be lower, since you'll reduce the steel (7,75 kg/m) and replaced with mineral slurry (let say 2,0 kg/m for copper ...

This paper compares two deconvolution methodologies used to estimate residence time distributions (RTD) in industrial closedcircuit ball mills. Parametric and nonparametric deconvolution techniques were evaluated. Both techniques allowed for direct RTD estimates from inlet and outlet tracer measurements in the mills, with no need for mass balances nor assumptions to correct the effect of the ...
