Scraper Conveyor
A scraper or drag-chain conveyor uses flights attached at intervals along a chain to move bulk material through a trough, horizontally or on an incline. It is widely used in underground coal mining, cement, power and metallurgy. Wear parts are concentrated in the flights, chains and trough system.

Materials for similarly named parts may differ by OEM, machine model and operating conditions. Confirm the machine model, drawing and measured dimensions before ordering or manufacture.
Material Information
- Mn13 manganese steel: approximately 11-14% Mn, with impact-induced work hardening for large-lump impact duties.
- Hardox 400/500 are candidate wear-resistant plate grades. Confirm hardness against the specific product, thickness and material certificate.
- Confirm chain material and heat treatment against chain type, size, breaking load, fatigue requirements and OEM specifications.
- Check pin diameter, fit, surface treatment and impact-fatigue requirements against the actual chain design. Do not add inserts without supporting design drawings.
