PVC/PVG Solid Woven Belts for Underground Mining

PVC/PVG Solid Woven Conveyor Belt

JINFLEX PVC/PVG solid woven conveyor belts are mainly designed for underground coal mining (wet/dusty environments) and also used in metallurgy and chemical industries—suitable for conveying coal, coking coal, mineral powder, and non-corrosive bulk materials.

Our PVC/PVG solid woven conveyor belts comply with multiple national and industrial standards, including China (MT914-2008, MT668-2019 for flame-resistant), Germany (DIN22131), the United States (RMA), Japan (JIS6369), Australia (AS1333), and international standards (ISO).

PVC/PVG Solid Woven Conveyor Belt

Product description

The PVC/PVG solid woven conveyor belt is made of a "solid woven core + PVC/PVG cover rubber" through impregnation, plasticization, and vulcanization:

Solid Woven Core:

High-strength polyester/cotton blended woven core, bearing tensile loads with low elongation (≤1.5% at 10% load).

PVC Cover Rubber (PVC Type):

Top + bottom PVC cover rubber (single side thickness ≥1.0mm), with flame-resistant and anti-static properties; suitable for ≤16° incline transport.

PVG Cover Rubber (PVG Type):

Top + bottom rubberized PVC cover rubber (more flexible), with better wear resistance; suitable for ≤20° incline transport.

Adhesion Layer:

Ensures tight bonding between core and cover rubber, avoiding layer separation under low-temperature/humid conditions.

Features and Benefits

■ Excellent Flame Resistance & Anti-Static

Meets MT668-2019 standard: Alcohol combustion time ≤10s (average ≤3s), propane combustion damage length ≤1250mm, surface resistance ≤3×10⁸Ω—prevents static explosion in underground mines.

■ High Tensile Strength & Stable Transport

Solid woven core has longitudinal tensile strength up to 1600N/mm, bearing heavy loads; low elongation ensures stable conveying speed, no material deviation.

■ Good Wear & Impact Resistance

PVG type cover rubber has Shore abrasion ≤150mm³; solid core resists impact from falling coal/ore, reducing belt damage.

■ Adaptability to Humid Environments

PVC/PVG cover rubber is water-resistant (water absorption ≤1.5%); suitable for underground wet mines and tunnel construction.

■ Easy Splicing & Maintenance

Cold vulcanized splice is available (simple operation); light belt weight (11-17kg/m²) reduces conveyor drive load, lowering energy consumption.
