New patented milling technology has the potential to meet the powder and fine grinding requirements of waste glass that were previously regarded as uneconomic. UK based International Innovative Technologies Ltd. (IIT) has developed new grinding technology that combines low energy consumption with a compact size and powerful grinding force. As a result as well as being suitable for the conventional grinding of a wide range of minerals and materials the highly efficient and versatile milling system also has the capability to economically convert waste glass into fine powders for a range of recycling applications. The new m-series powder mill from IIT comprises a technically advanced modular design capable of fine grinding soft medium and hard materials (to 9.5 on the Mohs scale) to 90% passing 45 microns and below. IIT has successfully used the new technology for the successful milling of glass waste to 50-75 microns to demonstrate the feasibility and cost effective production of powdered glass product for potential use in recycling applications such as a fluxing agent in brick manufacture and in filtration applications. Compact and powerful the centrifugal grinding mechanism of the m-series is extremely energy efficient with the vertical material flow path and special roller assembly ensuring that the force produced is translated into maximum particle grinding power. As a result rather than rely on airflow to carry the feed materials through the mill and into contact with the grinding media the new IIT mill utilizes natural centrifugal and gravitational forces to maximum effect. As a result extremely low electrical energy input is required relative to particle size and volume of powder output with specific energy consumption typically between 5kWh/T and 10kWh/T. Multi stage grinding is achieved through the incorporation of a number of grinding modules in series with particle size controlled both by the number of modules and rotational roller speed applied. The development of the new compact milling technology means that fine grinding solutions need no longer be restricted to traditional power hungry mills that absorb precious factory floorspace. On the contrary with traditional mill size and energy costs of converting granular materials into a fine powder no longer an inhibiting factor volume powder milling applications can now be easily integrated into previously inaccessible locations.
