The Mechanical Bar Screen Waste Cleaning Machine is designed for continuous removal of coarse solids and floating debris in industrial and municipal wastewater treatment systems. Installed at the inlet of treatment plants, it provides reliable pretreatment by intercepting large suspended materials, protecting downstream equipment, and improving overall treatment efficiency.
The equipment operates through a chain-driven rake mechanism that continuously collects debris from the screen surface and transports it to the discharge point. A rotary cleaning brush automatically removes retained materials from the rake teeth, ensuring efficient operation while minimizing clogging and maintenance requirements.
Manufactured from corrosion-resistant stainless steel or carbon steel, the machine is built for long-term operation in demanding wastewater environments. Its low-power drive system, stable transmission mechanism, and automatic cleaning process reduce manual labor while ensuring continuous and reliable performance.
The Mechanical Bar Screen Waste Cleaning Machine is widely used in municipal wastewater treatment plants, paper mills, textile factories, food processing facilities, chemical plants, and other industrial applications. It effectively removes plastics, fibers, leaves, wood chips, and other large debris, helping protect pumps, pipelines, and subsequent treatment equipment while reducing operating costs.
Investing in the right pretreatment infrastructure dictates the overall efficiency of your entire facility. This mechanical grille is engineered to resolve common operational headaches, transforming unpredictable waste streams into manageable, steady flows. By focusing on continuous operation and minimal intervention, it directly safeguards your downstream investments.
Uninterrupted Flow Assurance: The continuous rotary motion of the 48-piece tooth harrow prevents sudden blockages, ensuring your intake channels maintain optimal fluid dynamics without unexpected surging.
Automated Residue Management: A specialized top-mounted brush actively scrubs the harrow teeth, eliminating the buildup of sticky or fibrous materials that typically plague standard screens.
Exceptional Structural Integrity: Built to handle the heavy, wet weight of saturated industrial waste, the reinforced main frame resists warping and vibration under maximum load conditions.
Versatile Material Options: Depending on your specific effluent chemistry, select from ABS, Nylon 6, Nylon 1010, or Stainless Steel teeth to maximize the lifespan of the screening mechanism.
Seamless Integration: Designed to fit perfectly into secondary grill water inlets, functioning flawlessly in environments where large, damaging particles have already been filtered out.

Procuring capital equipment requires a partner who understands the intricate demands of large-scale fluid management. We do not just supply machinery; we deliver engineered reliability. Our manufacturing processes are rooted in precision, ensuring every unit that leaves our facility is ready to perform under the most grueling conditions.
Uncompromising Quality Control: Every component, from the transmission chains to the ABS teeth, undergoes rigorous stress testing before assembly.
Deep Engineering Expertise: Our designs are born from advanced technology and refined through years of feedback from diverse industrial applications.
Tailored Solutions: We recognize that standard specifications rarely fit complex projects, offering extensive customization for dimensions and materials.
Long-Term Partnership: We provide comprehensive technical guidance, ensuring your installation, operation, and maintenance phases are fully supported.
Global Standards: Developed on the basis of advanced technology from similar premium products globally, ensuring world-class performance.
The selection among ABS, Nylon 6, Nylon 1010, and Stainless Steel depends entirely on the chemical composition and temperature of your effluent. For highly corrosive or abrasive environments, Stainless Steel is recommended. For standard municipal wastewater, ABS or Nylon provides excellent durability and cost-efficiency while minimizing weight on the transmission chains.
While the discharge height is highly customizable during the manufacturing phase to match your specific site requirements, post-installation modifications are complex due to the fixed length of the main frame and transmission chains. We work closely with your engineering team beforehand to ensure the exact dimensions are fabricated for a perfect fit.
If the multi-tooth screen encounters an immovable object or experiences a sudden surge in solid mass that exceeds the motor's rated capacity, the overload protection instantly trips. This halts the driving device, preventing motor burnout and protecting the transmission chains from snapping, allowing your maintenance team to safely clear the obstruction.
This specific model is optimized for installation at the water inlet of secondary grills or water intake units where exceptionally large, heavy boulders or logs have already been removed. It excels at capturing medium to fine debris, fibers, and suspended solids that pass through primary coarse fences.
The rotary cleaning brush is designed for longevity, but its wear rate depends on the abrasiveness of the captured waste. We recommend a visual inspection of the bristles monthly. Under normal municipal or light industrial conditions, the brush typically requires replacement only once every 12 to 18 months, which is a swift, straightforward procedure.
