Effect of Slurry Solids Concentration and Ball Loading on ...
02-03-2014 · Table 2 presents experimental results of the effect of mill ball loading and slurry solids concentration on residence time and holdup. The measured residence times were - obtained from the RTD data using equation 3. Since the mill feed was relatively fine with d 50 < 150µm, the settling velocity of particles in slurry would be very slow hence it
