• 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.

Modular Design – self-containedcutter cartridge is easy to remove.Uni-body housing stays in place during maintenance so change-outs arequick and easy.

Flow Capability • In-line: up to 274 m3/hr. (1200 GPM) • In-channel: up to 774 m3/hr. (3400 GPM)

MUFFIN MONSTER® FEATURES & BENEFITS



Dual Shafted Grinder• Capable of grinding a wider variety of solids than single shafted machines.• Low speed operation results in higher torque and fewer interrupts.• Dual counter-rotating shafts direct materials toward center of shafts

Controls – PLC based control system with automated load sensing and reversals.

MUFFIN MONSTER® FEATURES & BENEFITS



Mechanical Shaft Seals• High pressure capability – 6 bar (90 psi)• No seal flush required and no packing gland to adjust• Hex Drive seal utilized on Channel versions

UNIQUE MUFFIN MONSTER® FEATURES

Also available on Macho Monsters.



High Flow Side Rails for Channel Models• Increase flow and decrease headloss• Deflect solids into the cutting chamber





Cutter Design Options• Various cutter combinations ensure optimum performance for different types of applications.





Low Profile Bottom End Housing

• Integral bushing deflector guides solids into the cutting chamber

• Low profile ensures minimum headloss.

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
