Why Smooth Surface Matters in Wear Liners
Bulk solids such as coal, copper concentrate, cement raw mix, and ores have a natural tendency to stick, build up, or form ratholing in bins, chutes, and hoppers. Standard wear material surfaces can create
drag and material hang-up.
Independent testing confirms that the
RapidFlow® finish significantly reduces wall friction, producing
flow characteristics better than stainless steel 304 2B finish—an industry benchmark for smoothness.
In real-world testing at coal-fired power stations and mining operations, RapidFlow has shown:
- Reduced chute and hopper blockages
- Improved flow in chutes with minimal flow angles
- Improved discharge consistency
- Lower downtime for cleaning and maintenance
- Extended equipment life by protecting against high wear zones
Backed by Independent Flow Testing
Laboratory flow property evaluations by Independent Companies provide strong evidence of RapidFlow’s performance:
- Wall friction and chute angle tests confirm that
RapidFlow® SA1750CR and SA2000 grades deliver similar or better flow than stainless steel liners when handling coal.
- Dynamic Adhesion Drop Tests conducted with copper concentrate demonstrated that RapidFlow showed
virtually no material build-up, averaging less than
0.1 g of adhesion per test, far outperforming other liners like TIVAR 88.
- RapidFlow’s
surface roughness (Ra ≈ 0.2–0.3 µm) is smoother than most polymer liners and significantly smoother than standard carbide overlay finishes.
This means operators can rely on
RapidFlow® not just for durability, but for predictable, reliable flow performance—even with cohesive or moist materials.

Where RapidFlow® Excels
RapidFlow® is the ideal choice for industries where
material flow reliability is just as critical as wear resistance, including:
- Coal-fired and biomass power plants – preventing bunker and chute plugging
- Mining & mineral processing – ensuring consistent ore and concentrate handling
- Cement plants – reducing buildup in raw feed chutes and silos
- Steel and foundry operations – improving scrap and slag flow handling
- Ports and terminals – keeping shiploader and transfer chute systems operating smoothly
The
RapidFlow® Premium Smooth Surface Carbide Overlay Plate is more than just a wear liner—it is a
flow assurance solution. By eliminating the tradeoff between maximum wear resistance and smooth material handling, RapidFlow® ensures that your plant operates
safely, efficiently, and with reduced maintenance costs.
Whether your challenge is abrasive wear, sticky material, or flow stoppages, RapidFlow® delivers
the best of both worlds—superior wear life and reliable material movement.
