What the PVG800 Conveyor Belt Is
The PVG800 Conveyor Belt is a solid-woven, PVC-impregnated belt designed for underground coal mining and other demanding bulk material handling. The designation PVG stands for PolyVinyl chloride with Grade, and 800 refers to the belt’s longitudinal tensile strength of 800 N/mm. Unlike multi-ply fabric belts, this belt has a single solid carcass that resists moisture, ripping, and impact. It is a common choice for coal mining conveyor belt systems where flame resistance is mandatory.
Construction and Key Features
The PVG800 Conveyor Belt is built around a strong solid-woven fabric core. The core is fully impregnated and coated with PVC compound, creating a homogeneous, non-layered structure. This design delivers excellent resistance to water, acid, and alkali, and prevents delamination. The belt also offers anti-static and flame retardant properties, making it suitable for underground mining environments. The cover is typically smooth but can be supplied with chevron or other patterns on request. Common cover thicknesses range from 3+1.5 mm to 8+3 mm, depending on the application.
Typical Applications
Where bulk material must move safely and reliably, the PVG800 Conveyor Belt performs well. It is widely used in:
- Underground coal mining conveyor systems
- Coal preparation plants and power plants
- Ports and ship loading facilities
- Cement plants and quarries
- Steel plants and foundries
- Sand making and stone crushing plants
Because the belt resists flame and static, it is often the specified choice for underground mining conveyor belt systems in coal mines. It also handles abrasive materials such as ore, rock, and aggregate when the cover grade is selected correctly.
Available Specifications
PVG conveyor belts come in a range of strengths and widths. The PVG800 Conveyor Belt is one grade within the PVG family. The table below gives common reference values; actual specifications vary by manufacturer and should be confirmed before ordering.
| Parameter | Common Range / Example |
|---|---|
| Longitudinal strength | 800 N/mm (PVG800) |
| Belt width | 650 mm to 1800 mm (e.g., 800 mm, 1000 mm, 1200 mm) |
| Cover thickness | 3+1.5 mm, 4+2 mm, 5+2 mm, 6+2 mm, 8+3 mm |
| Carcass type | Solid woven |
| Surface | Smooth or patterned |
When selecting a belt, consider the material size, drop height, and troughability. The PVG800 Conveyor Belt can be paired with various conveyor idler roller types and conveyor pulley designs to match the conveyor profile. Drive pulleys, tail pulleys, and bend pulleys each serve a different function and must be specified accordingly. Proper conveyor bracket selection also affects belt training and life.
Buyer’s Checklist
Before purchasing a PVG800 Conveyor Belt, gather the following information:
- Required belt width and length
- Material type, lump size, and temperature
- Flame retardant and anti-static requirements
- Cover thickness and grade
- Pulley diameters and conveyor layout
- Expected annual tonnage and maintenance plan
Keep in mind that belt width does not dictate pulley diameter; both are determined by conveyor design. Work with your supplier to confirm the correct PVG grade and cover for your site. For comparison, EP conveyor belts and steel cord conveyor belts are used in other contexts, but they are not substitutes for the PVG800 in underground coal service.
