JWC - Muffin Monster Grinders

Muffin Monsters wastewater grinders effectively reduce the particle size of solid waste in a wide variety of applications. Our Monsters easily grind wood, plastics, rocks, nuts, bolts, wire, sludge and just about any other foreign material that can cause damage to process and waste water equipment.

JWC understands the expense incurred to fix pumps, belt presses and other equipment that is easily damaged by solids. Parts, labor, overhead and plant downtime all add up, not to mention hours of aggravation. That's why numerous industries throughout the world use Muffin Monster® sewage sludge grinders to protect their valuable equipment and eliminate the need for constant monitoring to keep equipment operating.

Mini Monster® Model 20000 Problem solids are now easier than ever to reduce! Based on the same proven technology as our patented Muffin Monster®, the Mini Monster is designed to serve small volume applications in pump stations, pre-treatment systems and treatment plants, as well as package treatment plant inlet systems. The Mini Monster is equipped with a standard 3 HP (2.2kW) motor making it the perfect candidate for in-line sludge grinding, thus reducing troublesome solids and protecting pumps and process equipment from damage. The system is easily serviced – the cutter cartridge and drive system can be removed as one assembly, leaving the housing in-line during repair.
