What the PVG800S Conveyor Belt Is
The PVG800S Conveyor Belt is a solid-woven, PVC-based belt built for tough conveying duties where a fabric-core belt with flame retardant and anti-static properties is preferred over heavier steel cord construction. In the PVG family, the 800S designation points to a belt of roughly 800 N/mm tensile strength class, and the “S” suffix typically marks the flame retardant, anti-static variant used in coal mining and other underground operations. Buyers in the coal mining, cement, power plant and quarry sectors often specify this belt because it balances strength, flexibility and safety behavior in one product.
The name is also written as a PVG800S flame retardant conveyor belt, and it belongs to the same product family as the broader PVG conveyor belt range. It is not a replacement for an EP conveyor belt or a steel cord conveyor belt; it is a distinct solid-woven construction with its own selection logic.
How the Belt Is Built
Unlike multi-ply fabric core belts, the PVG800S uses a solid woven carcass. Warp and weft yarns are interwoven into a single body and then impregnated with PVC paste, with covers applied on both faces. This construction gives the belt good resistance to tearing, impact and moisture, and it resists delamination because there are no separate plies to peel apart.
Typical construction details include:
- Solid woven carcass with PVC impregnation for a compact, flexible body
- Flame retardant and anti-static additives for underground coal mining service
- Cover thickness commonly in the 2 to 6 mm range depending on duty, with values set by design
- Standard widths such as 800 mm, 1000 mm, 1200 mm and 1400 mm, with other widths made to order
Because the belt runs on conveyor pulleys, idler rollers and a supporting conveyor bracket frame, correct alignment and roller condition matter as much as the belt itself. A worn idler roller or a misaligned conveyor pulley can shorten belt life on any installation.
Where It Fits in the Plant
The most common home for this belt is underground coal mining, where flame retardant and anti-static behavior are required for safety. It also appears in surface coal handling, cement plants, power stations, sand and gravel yards, and port bulk terminals where moderate tensile strength and good troughability are needed.
Typical duties include:
- Main haulage and gate road conveying in coal mines
- Raw coal and product transfer in power plants
- Clinker and limestone handling in cement works
- Aggregate and ore transport in quarries and processing plants
For abrasive ore or long overland runs, a heavy-duty mining conveyor belt with a steel cord or high-strength EP carcass may be the better choice. The PVG800S is generally selected for medium-strength runs where safety and flexibility are priorities.
Specifications Buyers Should Confirm
Exact figures vary by manufacturer, so treat the table below as reference data rather than a fixed supply promise.
| Item | Common Reference Range |
|---|---|
| Belt type | PVG solid woven, flame retardant, anti-static |
| Strength class | PVG800S, nominally 800 N/mm class |
| Widths | B650, B800, B1000, B1200, B1400, B1600 |
| Cover thickness | 3+1.5, 4+2, 5+2, 6+2 mm |
| Top cover options | Smooth, or chevron / patterned for inclined runs |
| Service temperature | Standard range, with cold resistant grades for low temperatures |
| Applicable conveyor parts | Idler roller, conveyor pulley, conveyor bracket |
Belt width and pulley diameter are matched by conveyor design, not by a single fixed rule. A 1000 mm belt, for example, may run on different pulley sizes depending on the drive power and take-up arrangement.
Selection and Maintenance Notes
When choosing the belt, confirm the required flame retardant and anti-static grade, the maximum lump size and impact energy at the loading point, the trough angle and the pulley diameters. For steep inclines, a chevron conveyor belt or a corrugated sidewall conveyor belt may be more suitable than a smooth PVG800S. Where oil or heat is present, an oil resistant conveyor belt or heat resistant conveyor belt should be considered instead.
On the conveyor itself, keep idler rollers turning freely, check conveyor pulleys for lagging wear, and inspect the conveyor bracket and frame for alignment. Store spare belt rolls flat in a dry place and avoid sharp bends. For more information on matching belts to conveyor pulleys and idler roller layouts, see our guide at conveyor belt selection and our notes on idler roller maintenance.
Whether the job is coal mining, cement, power generation or quarry work, the PVG800S Conveyor Belt remains a practical choice when a solid-woven, flame retardant belt is specified. Confirm the exact grade and dimensions with your supplier before ordering.
