Grinders (also called comminutors) provide protection for pumps and other downstream equipment, helping to minimize expensive and unplanned maintenance.

JWC Muffin Monsters and Channel Monsters are dual shafted, slow-speed, high-torque grinders which shred material such as rags, wood, flushed wipes, hair, clothing, plastic and other debris into small particle sizes.


JWC Environmental provides Muffin Monster and Channel Monster grinders in both inline and open channel configurations.


JWC grinders serve in pipelines, manholes,

pump stations and headworks for applications such as: sewage pump stations, sludge lines, septage/grease receiving stations, influent structures, solids dewatering, correctional facilities, schools, business complexes and airports.


Multiple types of cutters and drive configurations are available for your site specific needs.
