Innovative Design for Energy-Efficient Grinding

An overview of new size reduction technology involving the use of two-mass natural frequency vibration applied to a totally enclosed elongated drum. Material moves with a drum-like rotary motion with exposure to constant, aggressive, high frequency agitation for faster reduction and enhanced product quality. A proven, patented design with few moving parts, a vibrating mill drum provides the desirable environmental benefits of a totally enclosed rotary drum but without the same interfacing difficulties. Natural frequency design has reduced energy demand which is met by low horsepower, self-contained, motorized drives to dramatically reduce the cost per ton of finished product.
