Conveyors

Back to products

Conveyors are essential in wastewater treatment plants for the safe, clean, and reliable transport of solids between process steps. They are commonly used to move screenings, grit, and dewatered sludge cake from preliminary treatment and dewatering equipment to containers, skips, or storage areas.

PMC Engineering supplies conveyor solutions selected for the duty and site conditions — including screw conveyors (shafted or shaftless), inclined conveyors, and belt/chain-type conveyors where required. Our approach focuses on practical operation: enclosed transfer to minimize odor and spillage, durable construction for abrasive media (especially grit), and straightforward maintenance for continuous plant operation.

Typical applications

Screenings transfer from mechanical screens and compactors
Grit removal discharge (often via inclined screw conveyors)
Sludge cake transfer from filter presses and dewatering systems
Transport between hoppers, containers, and storage points

Key Benefits & Features

Our conveyor designs are selected to match the handled material and duty cycle while keeping operation clean and maintenance simple.

Common conveyor types
• Screw conveyors (shafted / shaftless) for screenings, sludge cake, and general solids transport
• Inclined screw conveyors for lifting solids to discharge points
• Belt / chain conveyors (project dependent) for higher capacities or specific layouts

Design highlights
• Enclosed conveying for improved hygiene, reduced odor, and minimized spillage
• Robust construction for continuous industrial operation
• Abrasion-resistant solutions for grit service (material/coating selection based on duty)
• Smooth transfer from hoppers and outlets to avoid clogging and bridging
• Retrofit-friendly layouts for existing plants

Typical technical parameters (project-specific)
• Conveying capacity (m³/h or t/h) and bulk density
• Material type (screenings / grit / sludge cake) and moisture content
• Conveyor length, inclination angle, and inlet/outlet arrangement
• Material of construction (e.g., carbon steel with coating, SS304/SS316 where required)
• Motor power, gearbox selection, and protection class (indoor/outdoor)

• Materials: Carbon steel (coated) or SS304/SS316 for corrosive/hygienic areas
• Abrasion protection: Wear liners / reinforced wear zones for grit applications
• Conveyor configuration: Shafted or shaftless screw, horizontal or inclined, custom inlets/outlets and chutes
• Odor & spillage control: Covered/enclosed troughs, sealed transitions
• Drive & control: Heavy-duty gearmotor, VFD-ready speed control, overload protection
• Maintenance & safety: Inspection covers, clean-out points, guarding and E-stop package
• Accessories: Support frames, mounting brackets, flexible connectors, container/skip discharge setups
• Spares & service: Recommended spare parts kit and optional commissioning support
