Fine Mills Grinding Turning Waste Into Value: New Fine Mills
New milling technologies can help to access fine grinds of bulk and waste materials that were previously regarded as uneconomic. Necessary for these applications are low operation costs (that come with low energy consumption) with compact size and powerful grinding force.
British International Innovative Technology (IIT) has developed a new grinding technology that can be used for a wide range of materials‚ but also on mineral fine grinds and industrial by-products. IIT claims that using new millig technology could help to turn these materials, previously regarded as waste, into commercial products. Their new m-series powder mill features a modular design capable of grinding soft‚ medium and hard materials (to 9.5 on the Mohs scale) to 90% passing 45 microns and below. The m-series' compact centrifugating grinding is ernergy efficient as it translates most of the force into grinding power by using a vertical material flow path and special roller assembly. Specific energy consumption is typically between 5kWh/T and 10kWh/T. Managing director‚ George Ord‚ says: “In those areas where milling technology could not previously handle uneconomic materials efficiently‚ the low energy features of the m-series have opened up a range of new opportunities – particularly in the area of recycling and with certain plastic and glass waste. Turning scrap into a fine powder means it can be economically used for recycling.”
