1. Solids enter grinders through open channel.
2. Solids are captured and directed into the cutting chamber by rotated screening drum.
3. Most sewage and solids smaller enough pass through the rotated screening drum.
4. Solids pass through cutters for size reduction.
5. Solids are cut into smaller particles and no threat to downstream equipment.
Materials of Construction
Motor: Customized, multiple power options
Reducer: Planet gear reducer, good ability to against the load impact
Cutter and spacer: heat-treated alloy steel 4130 with surface harden evenly.
The hardness is not less than 45~50HRC
Shaft: heat-treated alloy steel 4140
Mechanicals Seals: Tungsten Carbide faces
Housings: Ductile cast iron ASTMA 536
Frame: Stainless steel (304,316)
Standard: coil made of 304 stainless steel
Optional: perforated, stainless steel drum with 6mm openings and up.
Ease and Flexibility of Installation
Adapts to most existing pipelines with little or no modification
Pressure capability to 6.3kg/cm2;
No seal flush required and no packing gland to adjust;
High-Flow Side Rails
Increases flow capacity and decreases head loss
Deflects solids into the cutting chamber
Dual Shaft Design
Low-speed, high torque grinders handle rags, rocks, wood, clothing, plastics and other debris
Capable of handling a wider variety of solids than single shafted machine
Customized cutters with various tooth configurations to meet special application
Tianizing cutter and spacer optional.1.5-2 lifetimes more than general cutters.
Low Profile Bottom end housing
More of the cutting chamber is utilized during low flow
Top Fasten Devices
Easy to fasten without lifting out of the channel
Shaftless Rotated Drum
Shaftless design can avoid of winding or wrapping by rag and trash
Small space between Rotated Drum and cutters
Small space between Rotated Drum and cutters can captures more solids
Bushing Deflector Device
Bushing deflector diverts solids and rags into cutters and protecting seal assemblies from sands and rocks.
