Product Overview
The Rake-Type Mechanical Bar Screen is a tough, self-cleaning screening system engineered for consistent coarse solids removal at municipal and industrial wastewater intake points. Its heavy-duty chain-and-rake operating system ensures unattended, uninterrupted operation, offering essential protection to downstream pumps and processes to stop clogging and prevent equipment damage.
Working Principle
Featuring uniformly designed rake teeth arranged in parallel and staggered formation, the system forms a heavy‑duty closed‑loop cleaning chain. Activated by a specialized motor and gear reducer, the chain travels steadily around guide sprockets to intercept, lift, and discharge debris automatically.

Applications
Our screening technology provides targeted solutions for both industrial and municipal sectors, focusing on efficient solids removal, valuable material recovery, and process optimization as key advantages. It is widely applied in industrial wastewater pretreatment across papermaking, slaughtering, tanning, sugar, brewing, food processing, textiles, dyeing, and petrochemicals, effectively removing suspended solids, floatables, and grit upfront to protect downstream equipment and improve plant efficiency. It also supports raw material and by-product recovery in papermaking, alcohol, starch, and food production by separating fibers, pulp, and organic solids, turning waste into profitable or recyclable resources. In municipal wastewater facilities, it improves treatment processes by replacing or supplementing primary sedimentation tanks, providing compact mechanical separation with consistent effluent and lower sludge production.
