The milling process generates heat and excessive mill temperatures are undesirable. It is clearly helpful, therefore, if the clinker is cool as it enters the mill. From an environmental and a cost viewpoint, the cooler reduces energy consumption by extracting heat from the clinker, enabling it to be used to heat the raw materials.

Mar 20, 2016 · Pulp Densities. Pulp densities indie 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.
