The Moyno Series 4 Annihilator Grinder twin-shaft, solids-reduction unit incorporates a removable quick-change cutter cartridge. The drive components and cutter cartridge can be removed from the flange housing as one assembly, allowing quick replacement and minimal downtime, says the company. The unit offers optimized cutter combinations, one-piece flange housing, improved counter-rotating intermeshing cutters and patented spacer cutters that more than double the cutting edges.
