On this episode of “Drilling Deeper,” P&Q managing editor Jack Kopanski sits down with PPI’s Tim Wolf to discuss the launch of Precision Composite Roller (PCR), a new composite idler roll option designed to tackle weight, corrosion and carryback challenges.
Wolf explains how PCR delivers a 30 percent weight reduction while remaining fully load capable, with temperature stability that rivals steel and outperforms aluminum in both hot and cold climates. He also breaks down how the PCR fits seamlessly into PPI’s CEMA C5 and above product lines, giving producers a lightweight, corrosion-resistant, low-noise option that’s dimensionally interchangeable with existing rolls and compatible with both new builds and retrofits. Wolf walks through the engineering behind PCR – including welded construction with tight TIR control, high-quality ball bearings, proven labyrinth sealing and an outer rock shield that has logged more than a decade of global field use in mining, aggregate and port applications.
The conversation explores key use cases where PCR shines, from large overland belts to portable plants where safer handling, easier maintenance and reduced carryback translate to more uptime and better belt health. Wolf also details PPI’s material options, such as GF HDPE (Georg Fischer high-density polyethylene), FRAS/SOF (fire-resistant, anti-static, oil-resistant formulation), UHMW (ultra-high molecular weight polyethylene) and dual-layer constructions. He also shares how producers should evaluate composite alternatives on performance, safety and total cost of ownership rather than price alone.
Looking ahead, Wolf outlines the product’s rollout – from initial availability through PPI’s international partner to an upcoming Iowa factory launch, which will bring local production of CEMA C5 to CEMA F rolls. For producers planning their next upgrade or attending major industry events, this episode serves as a practical guide to where composite idlers fit in the market, what signals to look for that indicate it’s time to switch and how to engage PPI’s field engineers and sales team to trial the PCR and optimize conveyor performance.
