Single Drum Channel Wastewater Grinder
（HCC-S2000）
Max. Flow: 2000m3/h Net Weight: 700kg
Operating Principle
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)
Screening Drums:
• Standard: coil made of 304 stainless steel
• Optional: perforated, stainless steel drum with 6mm openings and up.
Mechanical Characteristic
Ease and Flexibility of Installation
● Adapts to most existing pipelines with little or no modification
Mechanical Seals
● 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
Cutter Options
● Customized cutters with various tooth configurations to meet special application
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.
Control System Function
● PLC Control Cabinet with liquid crystal display, real time monitoring loading
● MODBUS standard field bus Communication interface and remote controllable
● Time adjustment, runtime and failure records query
● Automatic Reversal Function, time and times setting of reversal
● Leakage, Over Capacity, Overheating, Short Out and Lack of phase protection functions
● Authority setting function
