Mass/Volume Flow Determination. The relationship between the mass (M) and the volume flow (Q rates in a given stream is defined as: = the pulp density (solids and water) in lbs/ft 3 X = solids concentration in % by weight; Volumetric flow rate can be measured by flow meters, P-Q curve relationships for pumps or directly measured.

The load exerted by grinding balls on lignocellulosic biomass in a vibratory ball mill is significantly larger than the other mill types, resulting in the highest enzymatic hydrolysis yield. The glucose yields achieved were 95.2, 75.2, 61.0, and 52.8%, for vibratory ball mill, tumbler ball mill, jet mill, and centrifugal mill, respectively [ 52 ].

From the above example, we can determine the simple balance. 700=0.65*700 + 0.35*700=385+315. The 385 tons underflow will be recycled. 315 tons is the overflow will be taken for the further operations. Therefore 315 tons per hour is the fresh feed. The circulating load ratio is equal to 385 upon 315, so that is equal to 1.22.
