Raw Material Yard / Handling System
Skip Hoist Feed Systems (elevator alternative)
Can be replaced in some cases with enclosed Bucket Elevators for compact plants.
Chain Type: Heavy-duty forged chain for high-stress vertical lift.
Drag Chain Conveyors (Coke/ore mix transfer)
Purpose: Transfers burden mix to blast furnace or charge bins.
Chain Type: Drop-forged steel chain.
Design:
Horizontal or inclined layout with guide rails.
Multi-discharge gates and enclosed covers for dust control.
Pan Conveyors (Lime, DRI, Return Fines Feed)
Chain Type: Central chain with dustproof pans.
Design Notes:
Shock-proof construction for sudden loads.

Scrap Return Conveyors
Purpose: Carries steel scrap and trimmings back to melting or recycling zones.
Chain Type: Forged drag chain with customized paddles.
Design Features:
Rugged for sharp-edged scrap.
Magnetic separator integration (optional).
Billet/Slab Cooling Conveyors
Though primarily roller-based, some segments use slow-moving drag chains.
Application: Controlled discharge of hot slabs or billets.
Dust Handling / Baghouse / Fume Control
Ash & Dust Flow Conveyors
Chain Type: Enclosed drop-forged scraper chains.
Application: Fume extraction dust, baghouse fly ash.
