Correctly specified the mill will add no contamination to the product, or amounts so small as to be undetectable and of no significance. When grinding abrasive materials such as alumina, silica, iron oxides etc. the mill is lined with tungsten carbide or silicon carbide ceramics with MOH hardness of 9.6 (with diamond being a 10).
chamber for iron ore grinding. The single-compartment mill is ideal for the grinding of fine-grained feed material. One typical application is the combined grinding and drying of iron ore concentrate with a high feed moisture content (up to approx. 8 %). High-efficiency separators minimise the power consumption of dry grinding systems.
