• Muffin Monster dual shafted grinders feature slow speed rotation (typically 60/47 rpm)

• The slow speed offers high torque capability enabling the grinder to handle a wider variety of solids than single shafted machines.

CHANNEL GRINDERS

1. Solids and trash are transported to the cutting chamber via the waste stream.

2. Solids pass through the cutters for size reduction.

3. Ground material once again enters the waste stream, and the small particles pose no threat to downstream equipment.

4. Grinder features a load sensing and reversal system to clear jams, or alert operators to oversized debris.

MATERIALS OF CONSTRUCTION

Literature

Competition- Franklin Miller

Taskmaster in-line grinders• Non-unibody housing• Multi-cutter cartridge

– Inferior tolerancing

– Can’t replace individual cutters/spacers

Competition- Franklin Miller

Taskmaster in-channel grinders• Inferior high-flow side rail design

(patent action)• Multi-cutter cartridge

– Inferior tolerancing– Can’t replace individual cutters/spacers

Competition - Mono

TR Muncher• Cantilevered design (similar to Mini

Monster)• No bearings/seals on bottom of shafts

– Shaft deflection– Lesser duty

• Larger cutters and shafts than JWC• Investment cast cutters (tolerancing

less precise)

Competition - Mono

Series A, B Munchers

• Virtually same as JWC 30001 and 30002

• Mono was JWC licensee

Competition - Moyno

Annihilator• New in-line unit is a direct copy of JWC

design (30004T)• Cutter/Spacer design is inferior

– Decreased cutting power

– Decreased ability to clean out material

– (see JWC website for full analysis)

Competition- Chicago Pump

Sewer Chewer• Copy of old JWC technology• 5-tooth cutter results in larger particle

size• Gearmotor has less breakdown

torque
