What Is a 1200mm Wide Conveyor Belt?
A 1200mm wide conveyor belt is a heavy-duty rubber belt with a nominal width of 1200 millimeters, designed for high-capacity bulk material transport. This width is common in mining, coal preparation, cement plants, power stations, and large quarry operations where throughput and stability matter. The belt runs over a system of conveyor pulleys—drive, tail, and bend pulleys—each with a distinct role, and is supported by idler rollers and conveyor brackets along the route. The 1200mm width offers a good balance between load capacity and structural demands on the conveyor frame.
Construction and Common Specifications
The belt body typically consists of a fabric or steel cord carcass covered with rubber. For a 1200mm wide belt, common carcass types include EP (polyester-nylon) and NN (nylon-nylon) fabric cores, as well as steel cord construction for very high tension applications. Cover rubber grades are selected to resist abrasion, heat, oil, flame, or cold, depending on the service environment. Below are typical reference values; actual specifications are determined by design and may vary between manufacturers.
| Parameter | Common Range / Example |
|---|---|
| Belt width | 1200 mm (B1200) |
| Carcass type | EP, NN, steel cord |
| Strength series (EP) | EP200 to EP2000 (e.g., EP400, EP630, EP1000) |
| Number of fabric plies | 2 to 6 |
| Top cover thickness | 3 to 8 mm |
| Bottom cover thickness | 1.5 to 3 mm |
| Cover grade options | Abrasion resistant, heat resistant, oil resistant, flame retardant, anti-static, cold resistant |
For example, an EP1000 1200mm conveyor belt might use a 5+2 mm cover combination for general bulk handling, while a heat resistant variant could be specified for clinker or sinter transport. Steel cord belts in this width may use ST1000 to ST2500 ratings for long overland conveyors.
Where It Is Used
This belt width suits both surface and underground operations. In coal mining, a flame retardant 1200mm wide conveyor belt is often required for underground coal mining conveyors. In cement plants, abrasion resistant belts handle limestone, clinker, and additives. Power plants use them for coal and ash handling. Quarries and sand making plants rely on 1200mm belts for crushed stone and aggregate transport. Ports and ship loading facilities use wide belts for fast bulk transfer. The width also appears in recycling and construction waste sorting lines.
Related equipment such as conveyor pulleys (drive, tail, bend), idler rollers, and conveyor brackets must be sized to match the belt width and tension. A 1200mm belt does not dictate a single pulley diameter; pulley size is selected based on belt tension, carcass type, and required wrap angle.
Selection and Maintenance Notes
Buyers should consider material lump size, tonnage per hour, incline angle, and environmental conditions. For steep inclines, a chevron conveyor belt or corrugated sidewall belt may be needed, but these are different subtypes and not interchangeable with a standard flat 1200mm belt. For underground coal mining, PVG conveyor belts (e.g., PVG800S) are common, while EP or steel cord belts serve other duties. Always confirm cover grade and carcass strength with the supplier. Regular inspection of idler rollers, pulley lagging, and belt tracking helps extend service life. Splicing method—vulcanized or mechanical—also affects performance; endless conveyor belts are preferred for long runs to reduce joints.
When specifying a 1200mm wide conveyor belt, provide the application, material characteristics, and conveyor layout to your supplier. They can recommend the appropriate fabric core or steel cord construction, cover thickness, and safety factors.
