The DIMMINUTOR® provides automatic screening and grinding of liquid-borne solids with a straight-through open channel design. This unit reduces plastics, wood, vegetable matter, disposables and other oversized items to a fine particulate. The DIMMINUTOR’s unique features, heavy precision construction, dependable operation and simplified maintenance have earned it a solid reputation amongst operators and specifying engineers worldwide.

The DIMMINUTOR is designed for reliable operation and easy maintenance. For example, with its cantilevered design, the DIMMINUTOR needs no seals or bearings near the gritty channel floor. The unit’s screen is stationary so it never wears against bottom grit. Each cutter is interchangeable and cutters can be removed or adjusted independently. The unit’s seals and bearings are immersed in an oil bath for long life and low maintenance.
