Pulp Densities. Pulp densities indicate by means of a tabulation the percentages of solids (or liquid-to-solid ratio) in a sample of pulp. This figure is valuable in two ways—directly, because for each unit process and operation in milling the optimum pulp density must be established and maintained, and indirectly, because certain important tonnage calculations are based on pulp density.Firstly, conventional crushing and grinding circuits can be designed confidently on the basis of small-scale batch or locked-cycle tests requiring only 35 kg sample per test. Secondly, ASAG circuits can be designed using various methods each of which carries an element of risk commensurate with the experience, of the engineers involved and the ...
