Belt Conveyor Specifications
The figures below describe typical industry specifications for this class of equipment rather than a single fixed model. Use them to scope a requirement, then confirm exact figures against the supplied unit before purchase.
| Specification | Typical value |
|---|---|
| Common belt widths | 500, 650, 800, 1000, 1200 mm |
| Belt speed | 0.8–2.0 m/s; 1.0–1.5 m/s typical on small plants |
| Troughing | 20°, 35° or 45° three-roll idlers |
| Belt type | EP fabric, 3–5 ply; steel cord on long overlands |
| Drive | Head drum, lagged; 4–45 kW on plant conveyors |
| Take-up | Screw on short conveyors; gravity on longer ones |
| Inclination | Up to about 18° on a troughed belt without cleats |
| Idler spacing | 1.0–1.2 m carrying; 3 m return |
| Protection | Pull-cord, belt-sway, under-speed and belt-rip detection |
What a Belt Conveyor Is Used For
- Jaw to cone and cone to screen transfers
- Mill-feed and stockpile stacking
- Overland haul from pit to plant
- Loading bins and hoppers
- Waste and aggregate stacking
Maintenance Schedule
Most premature failures in this equipment class trace back to a missed routine check rather than a design fault. The intervals below are a practical starting schedule; adjust them to your duty cycle and the manufacturer manual.
| Interval | Task |
|---|---|
| Every shift | Walk the belt: tracking, spills, seized idlers, splice condition and that pull-cords work. |
| Weekly | Grease drive and tail bearings; check take-up travel remaining; inspect chute liners. |
| Monthly | Idler survey — seized idlers start fires and rip belts; replace on the spot. |
| Quarterly | Lagging, scraper and skirt inspection; belt-thickness and splice survey. |
| On splice | Hot or cold vulcanised splices outlast mechanical fasteners on any belt that runs continuously. |
Frequently Asked Questions
What belt width do I need?
From the t/h, the bulk density and the speed. A 650 mm belt at 1.2 m/s is the small-plant default and handles most 50–150 t/h crushing circuits. Going narrower and faster spills; going wider than you need costs idlers and structure for life. Size on surge, not on average.
Why does my belt run off to one side?
Loading off-centre is the usual cause, then seized idlers, then a tail drum that is not square. Track the belt with the training idlers only after the loading chute is putting material on the centreline. Chasing a tracking problem with the tail drum while the chute is skewed just walks the belt off the other way.
When do I need cleats or a chevron belt?
When the incline exceeds about 18° for smooth belts on crushed rock. Chevron profiles add a few degrees. Steeper than that is a pocket belt or a different layout. Do not steepen a smooth conveyor and hope — it will roll back the moment the feed gets coarse or wet.
