Mar 20, 2016 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 waysdirectly, 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
The pulp density is an important parameter which influences the grinding efficiency. In iron ore, for instance, a variation of 2 to 3% solid content in the slurry could lead to a difference up to 10% on the energy (kWh/T) for a similar grind.

The iron concentrate ore pulp after magnetic separation was selected as the simulation object. Its parameters are as follows 1) The grade of iron fine powder is 64.5% - 66.5%, and its main component is Fe 3 O 4, the impurity is mainly quartz, and the density is 2.2 g/cm 3 - 2.4 g/cm 3 when the moisture is 7%.
The maximum pulp density is usually about 50% solids by weight above that level small fluctuations in density will seriously affect separation. A coneshaped discharge of 2030 reduced angle usually produces optimum conditions for separation. Cyclone control is best obtained by optimising the feed density.
