Where Precision Meets Quality – QBF rubber Unveils Truly Endless Belt Line for Coal Feeder & Weigh Feeder Applications.

From calendering to vulcanization – every process built for accuracy, durability, and continuous weighing reliability.

Rooted in quality and driven by innovation, QBF rubber is an emerging force in the industrial conveyor sector, built on a long-term vision of engineering excellence. Today, the company announced the full operation of its dedicated endless skirt rubber belt production line, specifically engineered for coal feeders and weigh feeders.

Unlike conventional conveyor belts, skirt belts for feeders demand extreme precision – not just in tracking, but in dimensional stability, skirt alignment, and uniform thickness. Any deviation can directly affect weighing accuracy and material flow control.

QBF rubber’s production line addresses these challenges from the ground up:

Calendering: Ensures uniform belt thickness and flatness – critical for load cell accuracy in weigh feeders.

Forming:Achieves precise skirt geometry and consistent sidewall alignment, preventing material spillage and mistracking.

Vulcanization:Delivers stable vulcanized cross-linking, enhancing belt rigidity and skirt adhesion under continuous operation.

“Every process is a contest of precision. Every detail is a presentation of quality,” said a QBF rubber spokesperson. “For coal feeders and weigh feeders, even minor belt inconsistencies can compromise measurement. Our Truly Endless Belt line is built to eliminate that risk.”

The new belt line is designed to support high-frequency start-stop cycles, low elongation, and stable skirt stiffness – three essential requirements for gravimetric feeders in power plants, coal mines, and bulk material handling systems.

QBF rubber’s Truly Endless Belts are available in customizable widths, skirt heights, and rubber compounds to suit different coal moisture levels and abrasion conditions.
