Patented Design Features of the Moyno® Annihilator™ Improve Grinder Efficiency


The Annihilator’s field-proven, counter-rotating, hexagonal shaft design coupled with its 5-tooth, hardened steel cutters provide the maximum shredding strength necessary to process from 300 to 4,250 GPM (.43 to 6.12 MGD) of influent. When properly specified, the Annihilator prolongs the service life of downstream equipment such as pumps, sensors, monitors and valves.

For even greater performance, the Annihilator is fitted with patented, toothed cutting spacers that increase the unit’s efficiency, further decrease particle size and reduce the risk of failure from ragging. An exclusive seal cartridge assembly with mechanical seal and bearing on separate stainless steel sleeves allows for easy and quick replacement without purchasing complete cartridge designs.

Additional Annihilator features include the following:

  • Complements Moyno’s extensive wastewater treatment product offering

  • Dimensionally retrofits other twin shaft grinders

  • Electronic control panel offers protection from overload

  • Market leading sales, support and service network

  • Various drive, housing, cutter, spacer/cutter and shaft options

  • 3 to 5 hp motors
