In biomass facilities and wood processing plants, chain conveyors work relentlessly to move heavy materials such as woodchips, bark, pellets and other organic matter through production lines. Yet one persistent problem has plagued plant managers for years: steel scraper failures that bring entire operations to a halt.
The Steel Scraper Problem
Traditional steel scrapers face two critical issues in biomass applications. First, the sheer weight and abrasive nature of wood materials causes these metal components to buckle and deform under stress. When a steel scraper fails, it does not fail gracefully; it bends, jams and inflicts serious damage on conveyor chains and sprockets. The result is extended downtime, expensive repairs and replacement of multiple components beyond just the failed scraper.
The second issue is particularly relevant for biomass energy generation. When metal scrapers fracture, broken steel fragments contaminate the wood material stream. These metal pieces then travel into chippers and combustion furnaces, creating safety hazards, damaging equipment and requiring costly material screening processes.
The Wooden Solution
INNO scrapers take a counterintuitive approach. They are made from multi-laminated beech wood rather than steel. This is not ordinary timber; the wood undergoes specialised processing with thermosetting treatments, creating a composite material inspired by engineering principles used in Formula One skid pads and high-impact building protection systems.
Remarkably, INNO scrapers weigh just one-tenth of their steel equivalents while maintaining comparable durability under normal operating conditions. The true innovation lies in their failure mode. Instead of buckling and jamming when overloaded, wooden scrapers snap cleanly without damaging chains or sprockets. The broken pieces integrate harmlessly with the conveyed biomass material.
Practical Benefits for Biomass Operations
For facilities processing wood materials, this design offers seamless integration with existing operations. Broken scraper fragments pose no contamination risk; they are already wood, identical to the material being conveyed. When these pieces reach chippers or furnaces, they are processed or burned alongside the intended fuel source with no special handling required.
The weight reduction delivers additional advantages. Lighter scrapers reduce stress on conveyor drives, lowering energy consumption and extending the lifespan of drive components. Maintenance becomes simpler too; replacing a snapped wooden scraper takes minutes rather than hours of disassembly to repair chain damage. Plant managers report significant reductions in unplanned downtime. If an INNO scraper fails, conveyors can often continue running while a quick replacement is scheduled, avoiding immediate emergency shutdowns.
Available in three strength grades for different applications, INNO scrapers represent a practical rethinking of conveyor components. By matching material properties to biomass applications and using wood to move wood, they solve problems that steel cannot address effectively in these environments.
