Innovative Technologies (IIT) says a variety of product and technology upgrades have been incorporated into the latest version of its new milling equipment developed for fine grinding of minerals. As part of a program of continuous product improvement, IIT notes it has further developed its patented ‘m’ series of high efficiency vertical milling equipment with the introduction of a new second generation system suitable for the milling of a wide range of natural raw materials and industrial products, such as aluminium oxide, silicon carbide, zirconia, calcium carbonate and limestone products’ coal’ fly ash and different types of slag. The upgraded system uses heavy-duty castings in a range of modular grinding options to meet the needs of different materials, particle size requirements and throughput volumes. Grinding modules can also be arranged vertically in series for multi-stage milling required for the production of certain grades of material. Another option is a special twin mill system configuration, employing two grinding modules operating in parallel from a common feed, for complete flexibility of material throughput and increased production outputs. The new ‘m’ series mills also incorporate pressurized oil cooling and lubrication for extended bearing life, enhanced sealing integrity and the cooling of critical equipment assemblies. In addition, systems can also be provided with forced air circulation through the mill for product cooling and moisture removal where necessary. IIT’s mills and classifiers incorporate electronic control and process monitoring systems developed in collaboration with Siemens.
