Product Description
Technical Data
Applications
An inline sewage grinder is a device installed directly into a pipeline to shred and reduce solid waste in wastewater. Its primary function is to reduce the size of solids in raw sewage or process streams to prevent clogging, protect downstream equipment, and improve overall plant efficiency.
Ensure operational continuity with our Denor in-line channel sewage and wastewater grinder. Designed to protect your investment in downstream equipment, they employ a robust slow-speed, high-torque mechanism to shred and reduce solid matter.
The in-line channel grinder fits most existing in-line equipment or piping applications and does not require additional piping or modifications to the piping system. They protect municipal and commercial sewer systems, industrial facilities, and hospitals from costly damage and maintenance issues by ensuring efficient flow and operation.
Engineered for integration into pipeline systems, this inline sewage grinder offers the following customizable features:
Flanged Connections: Standard flanged inlets and outlets facilitate secure piping. Flange dimensions at both ends can be customized to match your specifications.
Grinding Components: The cutter type and configuration can be tailored to handle specific solid waste profiles.
Overall Dimensions: The product size can be adjusted to fit unique spatial or flow capacity requirements.
How it works:
Direct pipeline installation:
Unlike channel grinders, an inline wastewater grinder is integrated into the wastewater pipe system itself.
Powerful shredding:
It uses a robust twin-shaft mechanism or cartridge cutter system to crush and shred solids into smaller, manageable particles.
Straight-through flow:
The design allows for a straight-through path for the processed fluids and solids, preventing interference with the grinding process.
