The MEGA UF MILL-- Ultra Fine Rotary Pulverizing Mill is a patented, innovative, and commercialized method for particle size reduction to reduce, within seconds, solids that are capable of fracturing into a particle-sized powder. The Mega Mill reduces hard rock ores into particle sized powder of 200-400 mesh. It replaces a conventional ball mill, impact mill, hammer mill, tower mill, etc. It increases production. It processes pounds or tons per hour. It reduces operating costs. It requires low/minimal maintenance and much more. Ultra fine milling has created the potential to revolutionize the mineral processing industry due to the benefits attained through being able to economically mill finer and to enhance particle liberation for improved precious metals recovery.
