Moyno has engineered the new Max-Flow Annihilator(TM) Grinder System headworks debris handling system to protect downstream pumps, valves and process equipment in water treatment plants and their lift stations. This new grinder system can be used in place of bar rakes and screens as well as drum screen grinders for enhanced performance. The Max-Flow system contains two or more Annihilator grinders installed either in an in-line or staggered or offset design in a stainless steel retrieval frame in the headworks of a waste treatment system. The frame is prefabricated and engineered-to-order and includes guide rails to permit the independent retrieval of each grinder for easy maintenance. FRP or stainless steel control panels can also be installed to control the operation of each grinder independently using manual or automated control systems.
