When specifying material conveyor belt arrangements, several key factors must be considered to ensure optimal performance, safety, and efficiency. Below are the essential specifications and considerations:

1. Conveyor Belt Type & Material
– Belt Material: Rubber, PVC, PU, nylon, steel cord, or fabric (polyester, cotton).
– Cover Grade: Abrasion-resistant (AR), heat-resistant (HR), oil-resistant (OR), flame-retardant (FR), or food-grade.
– Reinforcement: Steel cables, fabric plies (EP or NN), or solid woven construction.
2. Belt Dimensions & Capacity
– Width: Typically ranges from 300 mm to 3000 mm (varies by application).
– Thickness: Depends on load; common range is 5–30 mm.
– Length: Customizable based on plant layout.
– Load Capacity: Measured in tons/hour (TPH); depends on belt speed and cross-sectional area.
3. Belt Speed & Inclination
– Speed Range: 0.5–5 m/s (adjustable based on material type).
– Maximum Inclination Angle:
– Flat belts: Up to 15°–20° for standard materials.
– Chevron/cleated belts: Up to 30°–45° for steep inclines.
4. Idler & Pulley Arrangement
– Carrying Idlers: Troughing angles (20°, 35°, 45°) for bulk materials.
– Return Idlers: Flat or V-shaped for belt stability.
– Drive Pulley: Lagged for better t.jpg)
tion; diameter depends on belt tension.
– Snub/Tail Pulley: Adjusts belt tracking.
5. Drive System
– Motor Power: Depends on load, speed, and elevation change.
– Gearbox/Reducer: Matched to motor RPM and required torque.
– Take-Up Unit: Gravity-based or screw-type for tension adjustment.
6. Loading & Discharge Points
– Feed Chute Design: Minimizes impact and spillage.
– Skirtboards & Sealing: Prevents material leakage.
– Discharge Points: Fixed or movable trippers/plows.
7. Safety & Control Features
– Emergency Stop Pull Cords
– Belt Misalignment Sensors
– Anti-Rollback Devices
