What Is a 1200mm Wide Conveyor Belt
A 1200mm wide conveyor belt is a standard-width belt used in bulk material handling systems where high capacity and stability are required. With a belt width of 1200 millimeters (often designated as B1200), it sits in the mid-to-large range of conveyor belt widths, bridging the gap between narrower 1000mm belts and wider 1400mm or 1600mm options. This width is common in mining, coal preparation, cement plants, power stations, and quarry operations where large volumes of rock, ore, clinker, or aggregate must be moved efficiently. The belt itself is typically part of a complete conveyor system that includes idler rollers, conveyor pulleys, and conveyor brackets, all selected to match the belt width and load conditions.
Construction and Materials
The construction of a 1200mm wide conveyor belt depends on the application. The carcass may be fabric-reinforced or steel cord. Common fabric types include EP (polyester-nylon) and NN (nylon-nylon). For demanding high-tension applications, steel cord belts are used. The cover rubber is selected for the environment: abrasion resistant for crushing and screening, heat resistant for cement or sinter, oil resistant for recycled materials, flame retardant for underground coal mining, and anti-static where required. Belt thickness is often specified by cover grade and carcass layers; typical cover combinations include 4+2 mm, 5+2 mm, and 6+2 mm, with 2 to 6 fabric plies. A 1200mm wide belt may also be produced with chevron patterns, corrugated sidewalls, or as an endless belt for specific conveying needs.
Typical Specifications
Below are examples of common parameters for a 1200mm wide conveyor belt. Actual values vary by manufacturer and design requirements.
| Parameter | Common Options |
|---|---|
| Belt width | 1200 mm (B1200) |
| Fabric core types | EP200, EP315, EP400, EP500, EP630, EP800, EP1000, EP1250 |
| Steel cord types | ST1000, ST1250, ST1600, ST2000 (for high-tension applications) |
| Cover thickness | 4+2 mm, 5+2 mm, 6+2 mm, 8+3 mm |
| Number of plies | 2 to 6 (fabric core) |
| Special constructions | Chevron, corrugated sidewall, pipe, endless |
When selecting a belt, the required tensile strength, cover grade, and number of plies are determined by the conveyor design, material lump size, loading conditions, and environmental factors. For instance, a 1200mm wide EP1000 belt might be used in a cement plant, while a 1200mm wide steel cord belt could handle high-tonnage ore transport in a mining operation.
Where It Is Used
The 1200mm width is widely employed in industries that handle large quantities of bulk materials. In coal mining, both surface and underground, flame retardant and anti-static belts are common. Power plants use heat resistant belts for coal and ash handling. Cement plants rely on abrasion resistant belts for limestone, clinker, and cement. Quarries and sand making plants use heavy-duty belts for crushed stone and aggregate. Ports and ship loading facilities often choose 1200mm wide belts for high throughput. The belt works together with idler rollers that support the load, conveyor pulleys that drive and redirect the belt, and conveyor brackets that hold the structure together.
Buyer’s Checklist
Before purchasing a 1200mm wide conveyor belt, consider the following:
- Material to be conveyed: its lump size, density, temperature, oil content, and abrasiveness.
- Conveyor design: belt speed, trough angle, transition distance, and pulley diameters. Note that belt width alone does not determine pulley diameter; the drive pulley, tail pulley, and bend pulley are selected based on tension and available space, and they are not interchangeable.
- Environmental conditions: underground coal mining may require flame retardant and anti-static properties; cold climates may need cold resistant covers.
- Belt construction: fabric core (EP or NN) versus steel cord, number of plies, cover thickness, and any special features such as chevron or sidewalls.
- Compatibility with idler rollers and conveyor brackets to ensure proper belt tracking and support.
For assistance in choosing the right belt for your application, consult with a conveyor belt supplier who can review your system requirements. Whether you need a standard EP conveyor belt or a specialized steel cord conveyor belt, the 1200mm width offers a versatile solution for many bulk material handling challenges.
