Product Description

Technical Data

Applications


Crafted in our factory: The Single Screen Drum Sewage Grinder, built with precision engineering.
 

Engineered for demanding applications, the Denor Single Drum Sewage Grinder integrates one durable rotating drum screen with powerful dual-shaft grinding cutters. Its adaptable frame (custom frame) allows flexible installation in various channel configurations.

 

This unique design maximizes solids capture and flow efficiency while preventing material wrap-around. By consistently reducing solid waste to fine, manageable particles, it eliminates clogs, protects sensitive downstream equipment (such as pumps and valves), and significantly lowers long-term operation and maintenance costs.

 

Single Drum Grinder Sewage principle:

 

1. Solids enter grinder area through open channel;

2. Solid particles are trapped by the drum and exported to the cutting room;

3. Solid particles are cut and pass through the cutting chamber;

4. The crushed particles flow downstream.

 

Denor offers a wide range of sewage grinders engineered for superior performance, reliability, and easy maintenance. Our innovative grinders, suitable for channel, inline, and gravity installations, are ideal for various applications, such as plant headworks, sludge lines, wet wells, pump stations and industrial effluent lines.

 

Wastewater Grinder provide a dependable solution for processing diverse waste and contaminants in wastewater. The channel wastewater grinder is widely used in open channel (well), wastewater lift pump stations, municipal sewage systems, industrial facilities and commercial buildings and residential complexes sewage pipe network engineering, etc.

Water Inlet Channel (well)

Water Inlet Channel (well)

Sewage grinders can pulverize suspended solids and floating debris in water channels into particles measuring 6mm to 12mm.

Sewage Lift Station Projects

Sewage Lift Station Projects

Sewage grinders can be installed at integrated lift pump station to reduce the size of solid waste, protect pumps, and ensure efficient wastewater transport.

Municipal Sewage Systems

Municipal Sewage Systems

Sewage grinders are used in municipal sewage pipeline systems to reduce the volume of solid waste, prevent pipe blockages, and protect pumps and other equipment during wastewater treatment.

Industrial / Commercial / Residential Areas

Industrial / Commercial / Residential Areas

Industrial, commercial, and residential areas all generate various types of solid waste. Sewage grinders can help manage this waste and maintain the smooth operation of the sewer system.
