Belt Conveyor Specification for Mining Applications
# 1. General Requirements
– Application: Underground/Open-pit mining (coal, ore, aggregates, etc.)
– Material Handled: Type (e.g., coal, iron ore), lump size (max. 300mm), bulk density (~1.6 t/m³), moisture content
– Capacity: 500–10,000 TPH (varies with belt width/speed)
– Conveyor Length: 50m–5,000m (or more for long-distance conveyors)
– Incline/Decline Angle: Typically 0°–18° (steeper angles require cleated/chevron belts)
# 2. Belt Specifications
– Belt Width: 650mm–2,400mm (common: 1,200mm–1,800mm)
– Belt Type: Multi-ply fabric (EP or steel cord reinforcement), abrasion-resistant cover (e.g., DIN 22102)
– Top Cover Thickness: 6–15mm (higher for abrasive materials)
– Bottom Cover Thickness: 3–6mm
– Tensile Strength: 630–8,000 N/mm (steel cord belts for heavy loads)

# 3. Drive System
– Motor Power: 15kW–2,000kW (depends on load/speed/length)
– Drive Type: Single or multi-drive with fluid couplings/VFDs for soft starts
– Pulleys: Head/tail/drive/snub pulleys; lagged for grip; diameter ≥1m for high tension
# 4. Idlers & Structure
– Carrying Idlers: 3-roll troughing (35° or 45°), spaced at 0.8m–1.5m intervals
– Return Idlers: Flat/spiral rollers, spaced at 2m–3m intervals
– Frame Material: Galvanized steel or stainless steel for corrosion resistance
# 5. Safety & Additional Features
– Safety Devices: Pull cords, belt misalignment switches, zero-speed sensors, fire-resistant belts (
