PVG Integral Belt Core Flame Retardant Conveyor Belt

The rubber-covered solution for wet, high-incline mining environments — where moisture, fire risk, and heavy loads demand more.

Wet Underground Coal Mines

The definitive application. PVG belts handle water spray, floor flooding, and high humidity without cover separation or performance degradation.

High-Incline Mine Tunnels

Rated up to 20°, PVG belts maintain grip and structural integrity on steeper conveyor paths where PVC-only belts are unsuitable.

Longwall & Roadway Conveying

Ideal for face-to-surface haulage where belts face continuous heavy loading, moisture, and occasional impact from falling material.

Tunneling & Civil Construction

Used in enclosed tunnel conveyors requiring flame retardancy and water resistance during extended underground operations.

Built for Wet Conditions and Steeper Inclines

The PVG Integral Belt Core Flame Retardant Conveyor Belt — also known as the rubber-covered solid-core flame retardant conveyor belt — is engineered for the most demanding underground mining conditions. Where the PVC series serves dry environments, the PVG series goes further: its dual rubber cover layers are chemically bonded to the solid PVC core, delivering superior cover-to-core adhesion strength and complete resistance to delamination even under continuous moisture exposure.

Manufactured in strict compliance with MT914–2008, the PVG belt is rated for incline angles up to 20° in wet, water-present, and humidity-intensive environments. It is the preferred choice for coal mines and tunnels where water ingress, heavy material impact, and fire risk occur simultaneously.

PVG vs PVC — What's Different?

Left Column — PVC Integral Belt Core:

Best for dry underground environments
Incline angle up to 16°
PVC cover on both sides
Excellent cost efficiency for standard mining conditions

Right Column — PVG Integral Belt Core:

Designed for wet and water-present environments
Incline angle up to 20°
Rubber cover bonded to PVC core on both sides
Superior abrasion resistance, cover adhesion, and moisture durability

FAQ

What makes PVG different from PVC conveyor belts?

The key distinction is the cover material and rated environment. PVG belts feature rubber covers on both sides bonded to a solid PVC core, giving them higher cover adhesion strength, better abrasion resistance, and the ability to operate in wet or water-present conditions at inclines up to 20°. PVC belts are designed for dry environments at up to 16°.

Can PVG belts be used in completely submerged or flooded conditions?

PVG belts are rated for wet and water-present environments including water spray and surface flooding typical in underground mines. They are not designed for full continuous submersion. Contact our team if your application involves extreme water exposure.

What incline angle can the PVG belt handle?

The PVG Integral Belt Core is rated for conveying inclines up to 20°, making it suitable for steeper underground tunnels and face conveyors where standard belts cannot be used.

How is cover-to-core adhesion tested?

Our PVG belts undergo peel adhesion testing as part of MT914–2008 compliance. The rubber cover layers are bonded to the integral core using a high-temperature vulcanization process that prevents delamination under mechanical stress and moisture exposure.

Do you supply belts for specific conveyor brands or OEM systems?

Yes. We manufacture to custom dimensions and can reference your conveyor system specifications to ensure a compatible belt profile. Please share your system drawings or contact details for a tailored recommendation.

What is the typical service life of a PVG belt?

Service life depends on load, speed, material type, and maintenance practices. In typical underground coal mine applications, a well-maintained PVG belt can achieve 18–36 months of service life. Our team can advise on installation and tensioning practices to maximize longevity.
