Slurry Solids Concentration by Weight. A classifying cyclone is treating 150 gallons/min of slurry. A plant technician has measured the pulp densities of the process streams using a Marcy density gauge and reported the following: Ï f = 1.08 gm/ml, Ï o = 1.03 gm/ml and Ï u = 1.20 gm/ml. Determine the volumetric flow rates to each stream.

The previous ball mill study was performed for a dry mill. Here we consider an overflow ball mill with feed and discharge of slurry as well as resident slurry included. This is modelled using the fully coupled DEM+SPH method. This mill is of the type used for processing cyclone underflow classified from a SAG mill product. 6.2.

Ball Mills. Ball mills have been used for the preparation of coal–oil and conventional coal–water slurry fuels, also in large sizes up to a capacity of 50 tonnes of coal per hour (Austin et al., 1984).
Slurry is a mixture of a solid and a liquid. The density of a slurry can be calculated as. ρ m = 100 / [c w / ρ s + [100 - c w] / ρ l] (1). where . ρ m = density of slurry (lb/ft 3, kg/m 3). c w = concentration of solids by weight in the slurry (%). ρ s = density of the solids (lb/ft 3, kg/m 3). ρ l .
