The specification of belt conveyors depends on their application, material handling requirements, and operational conditions. Below is a general outline of key specifications to consider when selecting or designing a belt conveyor:
1. General Specifications
– Type of Conveyor:
– Flat belt conveyor
– Troughed belt conveyor (20°–45°)
– Modular belt conveyor
– Cleated belt conveyor
– Incline/decline conveyor
– Magnetic belt conveyor
– Belt Material:
– Rubber (EP, NN fabric, steel cord)
– PVC/PU (food-grade, oil-resistant)
– Metal (wire mesh, chain-driven)
– Belt Width:
– Common widths: 300mm, 400mm, 500mm, 600mm, 800mm, 1000mm, 1200mm
– Belt Speed:
– Typically ranges from 0.5 m/s to 4 m/s (adjustable via VFD)
2. Load & Capacity Specifications
– Maximum Load Capacity (kg/m or tons/hour)
– Material Density (kg/m³) – Determines belt strength and width.
– Bulk Density of Material – Affects troughing angle and belt selection.
3. Belt & Pulley Specifications
– Belt Thickness: Usually between 3mm–20mm depending on material.
– Belt Tensile Strength: Measured in kN/m (e.g., EP200, EP315 for fabric belts).
– Pulley Diameter: Depends on belt type and tension (e.g., drive pulley Ø300–1000mm).
4. Drive & Motor Specifications
– Motor Power (kW/HP): Depends on load, speed, and incline angle.
– Drive Type: Head drive, tail drive, or center drive.
– Gearbox & Reducer: Helical gearbox for smooth operation.

5. Structural Specifications
– Frame Material: Mild steel (powder-coated), stainless steel (food industry).
– Support Rollers/Idlers:
– Carrying idlers spacing: ~1m for heavy loads (~3m for light loads).
– Return idlers spacing: ~2–3m.
