Common & Basic Formulas for Mineral Processing Calculations

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 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.

Mill (grinding) - Wikipedia

You don''t need the axle between the gearbox and waterwheel, but is helpful later when needing the space to surround the mill stone with Mk2 hoppers. Mechanical power is binary, it''s either on or off.

When steel is rolled back-and-forth through the same mill, this is a reversing mill. When it moves directly in a continuous process to other mill stands, this is a tandem or continuous mill. These can achieve far higher throughputs than a reversing mill. Tandem mills are associated with flat products and typically have 4 or 6 stands.
