UHMWPE Coal Bunker Hopper Liner PE Material Plastic Sheet

Our UHMWPE (Ultra High Molecular Weight Polyethylene) coal bunker hopper liner plastic sheets are a game-changer in the coal handling industry.
These sheets are made from premium UHMWPE material, renowned for its outstanding abrasion resistance. This property significantly extends the lifespan of the coal bunker hopper liners, reducing the need for frequent replacements and maintenance costs.
The low friction coefficient of UHMWPE ensures smooth coal flow, preventing material buildup and blockages in the hoppers. This not only improves the efficiency of coal handling operations but also enhances overall productivity.

Features

Superior Abrasion Resistance: 15 times more wear-resistant than steel, extending service life in high-flow hoppers by 3–5 years and reducing replacement costs.

Low-Friction Surface Technology: Coefficient of friction (COF) of 0.15 ensures smooth material discharge, preventing buildup of coal, ore, or grain even in humid conditions.

Extreme Impact Tolerance: Withstands 10kg weight drops from 2m height without cracking, critical for maintaining operational continuity in heavy-duty environments.

Chemical Inertness: Resistant to sulfuric acid, alkalis, and organic solvents, making it suitable for aggressive mining and chemical processing environments.

Application

Coal Power Plants: Lines bunker hoppers to eliminate material bridging, reducing manual intervention and improving feed system efficiency by 20%.

Grain Storage Facilities: Prevents wheat, soybean, and corn adhesion in silos, ensuring consistent flow during discharge and minimizing product waste.

Mining Conveyors: Protects chutes and transfer points from abrasive ore particles, reducing maintenance downtime and repair costs by 40%.
