Handling sticky materials in mining and minerals processing can create significant obstacles from equipment blockages and excessive wear to increased maintenance and operational inefficiencies. Successfully addressing these challenges requires specialised expertise and tailored solutions, according to Dewald Tintinger, Technical Manager at Weba Chute Systems.

“Sticky materials are notorious for causing inefficiencies in transfer systems,” says Tintinger. “To mitigate these issues, it is essential to partner with experienced solution providers who understand the complexities of material behaviour and transfer point design.”

Smarter designs for smoother operations

The flow of sticky materials can be improved significantly with thoughtful transfer point designs that minimise blockages and build-ups. Tintinger explains that optimised chute geometry is critical to maintaining material movement.

“By designing chutes to reduce impact forces and prevent material degradation, we create transfer point systems that operate more smoothly. Using durable linings, such as ceramic or rubber, further protects the equipment from wear and extends its service life,” he explains.

Controlling moisture levels is another vital consideration when dealing with sticky materials. Tintinger points out that excessive moisture increases material adhesion and build-up, disrupting flow. “Incorporating proper drainage, dust suppression or material conditioning systems helps maintain ideal moisture levels, which reduces the risk of blockages.”

Addressing material variability

Sticky material challenges are often exacerbated by inconsistent material properties, such as segregation or oversized particles. Tintinger highlights the value of blending systems and controlled crushing or screening to produce consistent material characteristics that promote smooth handling.

“These adjustments ensure the material moves effectively through the system, reducing the likelihood of disruptions,” he adds.

A holistic approach to material handling

An integrated view of the entire material handling process is essential for long-term success. Belt cleaning systems, for instance, are indispensable for preventing sticky material carryback that can lead to blockages at transfer points.

“Combining primary and secondary belt cleaners with tracking systems keeps belts clean and aligned, reducing wear and operational delays,” Tintinger notes.

Boosting productivity and efficiency

Tintinger emphasises that well-designed transfer points offer far-reaching benefits. “A proactive approach to managing sticky materials not only reduces maintenance and downtime but also optimises efficiency and productivity across the operation.”

“By addressing these challenges holistically, Weba Chute Systems continues to deliver innovative solutions that keep mining and minerals processing plants running smoothly, even in the stickiest situations,” he concludes.
