- Working Principle: A scraper conveyor chain operates within a trough. The chain, fitted with scrapers or flights, moves material along the bottom of the trough to a discharge point. It is ideal for slower-speed transport over short to medium distances, on inclines, and even in submerged applications.
- Primary Applications:
- Bulk Goods Transport: Grain, cement, minerals, and aggregates.
- Woodworking Industry: Moving wood chips, sawdust, and bark.
- Steel Industry: Handling slag, scale, and other by-products.
- Automotive Industry: Conveying parts through finishing or assembly lines.
- Environmental Technology & Recycling: Moving municipal waste, recyclables, and biomass.
