The industrial pin mill (also known as a universal mill, turbo mill, and impact mill) is a one pass grinding equipment ideal for achieving the micronization of bulk materials and powdered products. Common applications involve the fine grinding of sugar, salt, sodium bicarb, etc. The average achievable particle size range of the pin mill is around a d50 of 80 microns.

Pulp Densities. Pulp densities indicate by means of a tabulation the percentages of solids (or liquidtosolid 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.
