Mill scale (also called scale) is the flaky surface that forms on hotrolled steel. Its composition includes FeO (iron (II) oxide), Fe2O3 (iron (III) oxide), and Fe3O4 (iron (II,III) oxide). You will find mill scaling on steel sheets, plates, and profiles. It arises when you roll hot steel billets or iron in rolling mills.

High Shear Granulators produce a wet mass once the process is complete; it is typically discharged through a wet mill to break up any agglomerates (, oversize granules) and facilitate downstream drying, most often done in a fluid bed dryer. The discharge of a bottomdrive high shear granulator is noted in the schematic on the right.

The SPCC consists of a series of cyclone separators and calciners. Based on the nomenclature of FLSmidth, the SP configuration in Fig. 1 on the left is called separate line calciner (SLC) and the right configuration is called separate line calciner with inline calciner (SLCI). Fig. 1 shows that raw meal is fed into SP through two points, the right string (A string) and the left string (B string).

At several plants we have also found a rather sharp limit to the lime saturation factor, if good clinker grading is to be obtained; if this limit is exceeded the clinker becomes dusty. The clinker granulometry is important for the satisfactory operation ofany cooler: There must not be too much dust. Less than J5% minus mm (") is good.

The mill scale is not connected to the underlying surface. The oxides are pressed into the object with great force, however they are not actually attached to the surface but to the mill scale. Over time, for example during processing of the material, the mill scale will slowly but surely come loose, causing it to lose its protective effect.
