Non-drum Channel Wastewater Grinder
HCC-N920
Flow Rate：920m3/h Head Drop：444mm Net Weight：370kg
Operation Principle
1. Solids enter grinders through open channel.
2. Solids pass through cutters for size reduction.
3. Solids are cut into smaller particles and no threat to downstream equipment.

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)
Mechanical Characteristic
Ease and Flexibility of Installation
● Adapts to most existing pipelines with little or no modification
Mechanical Seals
● Pressure capability up 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
● Directs 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 Fastening Devices
● Easy to fasten without lifting out of the channel
Control System Function
