What a 1200mm Wide Conveyor Belt Is
A 1200mm wide conveyor belt is a heavy-duty bulk material belt built to a nominal 1200 mm (B1200) width. It sits in the mid-to-large range of standard belt widths, wider than common 800mm and 1000mm belts and narrower than 1400mm or 1600mm designs. In practice, this width is a popular choice for main haulage lines where a single belt must move high tonnages without becoming excessively stiff or costly to support.
The belt is only one part of the conveyor. It runs over idler rollers, wraps around the drive pulley and tail pulley, and is held in line by conveyor brackets and frame structures. Getting the belt width right matters because the belt, pulleys and idlers must be matched as a system, not selected in isolation.
Construction and Common Specifications
Most 1200mm belts are fabric-cored or steel-cord reinforced. Fabric Core Conveyor Belt constructions, including EP Conveyor Belt and NN Conveyor Belt carcasses, are widely used in this width. Multi-Ply Fabric Core Conveyor Belt designs with two to six plies are common, while Steel Cord Conveyor Belt versions suit long, high-tension routes. Cover rubber grades are chosen for the duty: Abrasion Resistant Conveyor Belt, Heat Resistant Conveyor Belt, Oil Resistant Conveyor Belt, Flame Retardant Conveyor Belt and Cold Resistant Conveyor Belt are all available in this size range.

Typical Reference Data for B1200 Belts
| Item | Common Reference Values |
|---|---|
| Belt width | 1200 mm (B1200) |
| Fabric strength grades | EP200, EP315, EP400, EP500, EP630, EP800, EP1000 |
| Steel cord grades | ST1000, ST1250, ST1600, ST2000 |
| Cover thickness | 4+2, 5+2, 6+2, 8+3 mm |
| Carcass plies | 2 to 6 plies, by design |
Specialty forms such as Chevron Conveyor Belt, Corrugated Sidewall Conveyor Belt and Pipe Conveyor Belt can also be produced at this width when the application calls for inclined transport or enclosed material handling.
Where the Width Fits in Real Plants
Mining Conveyor Belt systems often use 1200mm belts on main trunk lines, while Coal Mining Conveyor Belt and Underground Coal Mining Conveyor Belt installations favor flame retardant and anti-static grades. In cement plants, a 1200mm belt may carry clinker or raw meal; in power plants it feeds coal; in quarries and sand plants it handles aggregate and crushed rock. Port and ship loading conveyors also use this width for steady bulk flow.
Because the belt is wide, troughing idler rollers and return rollers must be sized for the load, and the drive pulley and tail pulley must match the belt tension and width. These are separate components with separate duties; a drive pulley cannot be swapped for a bend pulley, and idler types are not interchangeable with pulleys.
Buyer Checklist
- Confirm the required strength grade and carcass type for the conveyor length and incline.
- Match cover rubber to the material: abrasive ore, hot clinker, oily scrap or cold outdoor duty.
- Check pulley and idler compatibility with the 1200 mm width and the calculated belt tension.
- Decide whether an Endless Conveyor Belt or open-end spliced belt suits the installation.
- For underground or coal service, specify flame retardant and anti-static properties.
A well-chosen 1200mm wide conveyor belt, paired with correctly sized pulleys, idlers and brackets, gives a durable backbone for heavy bulk handling in mines, cement works, power stations and aggregate yards.
