Single-Drum Channel Monster for Municipal Wastewater Pumping Stations
Product Overview
The single-drum grinder screen adopts a compact single-drum structure and offers excellent performance, easy installation, and low maintenance requirements. It consists mainly of a rotating screen drum and a cutter assembly fitted with alloy cutting blades. The unit can shred difficult solids into smaller, manageable particles at flow rates of up to 1,200 m³/h.
The newly designed stainless-steel shaftless drum provides:
Higher solids-capture efficiency
Increased hydraulic capacity
Improved resistance to entanglement
Greater structural strength and durability
The drum-type grinder screen effectively intercepts and shreds solids, providing reliable protection for downstream pumps and other treatment equipment.
Working Principle
The cutter assembly uses high-strength alloy cutting blades developed through decades of technical improvement and design optimisation. These blades can shred a wide range of solids that could otherwise clog or damage downstream equipment and have proven suitable for demanding wastewater applications.
The operating process is as follows:
Solid materials enter the cutting area together with the incoming wastewater.
The solids are intercepted by the rotating screen drum and conveyed into the cutting chamber.
Most of the wastewater and sufficiently small particles pass directly through the drum screen.
Larger solids are shredded as they pass through the cutting chamber.
The shredded particles are discharged with the wastewater and flow downstream.
Applicable Operating Conditions
Suitable for high-flow applications.
Applicable to domestic sewage, stormwater, wastewater, and combined sewage and stormwater flows.
Capable of handling flexible waste and certain relatively hard solid materials.
Typical materials include:
Wood fragments
Aluminium cans
Plastic containers
Cloth and fibrous materials
Small quantities of stones
Product Features
Optimised cutter design provides efficient shredding performance and a long service life.
High hydraulic capacity makes the equipment suitable for large-flow applications.
The narrow screen openings provide effective solids interception and help control the size of the shredded particles.
A specially designed mechanical sealing system enables reliable long-term operation in harsh wastewater environments.
