Grinder improves cutting efficiency

July 29, 2009

The twin shaft solids reduction grinder is designed for trouble-free performance in meeting the broad needs of any industry requiring solids reduction or waste conditioning, according to the manufacturer. The grinder’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 of influent and ensure that solids are ground uniformly and efficiently. When properly specified, it prolongs the service life of downstream equipment such as pumps, sensors, monitors and valves. For even greater performance, the grinder utilizes patented, bi-directional cutting teeth on the spacers that increase the unit’s efficiency, further decrease particle size and reduce the risk of failure from ragging due to stringy materials. The exclusive seal cartridge assembly featuring the mechanical seal and bearing on separate stainless steel sleeves, allow for easy and quick replacement without purchasing complete cartridge designs.
