ABSTRACT:
Efficient process control of a rotary breaker is dependent upon the rate at which aggregate material is delivered to the rotary breaker. An improved pre-screening apparatus provides enhanced control of the amount of undersized material allowed to bypass the rotary breaker, thus allows some control of feed rate other than the upstream mining conditions. Further, a variable speed drive mechanism allows for enhanced control of the breaking process occurring within the rotary breaker. These improvements allow for the increase in maximum feed rate to an existing rotary breaker or allows for the installation of smaller and more economical original equipment. In addition, an improved discharge mechanism is provided to increase the discharge rates of a breaker without varying size or speed of rotation. These improvements allow for advanced automated process control.
