Conveyor rolls

For cold weather operation

Conveyor rolls
The demands on conveying systems multiply dramatically during the winter season, especially in those climates where snow and ice are the norm. Conventional conveyor rolls are made of steel, which causes numerous problems when the snow flies. Steel is a conductor, so temperatures on the outside of a steel can roll are transferred inside. Any moisture that builds up inside of a steel roller can cause serious damage to the roll, especially in the winter months.

Back on the outside, steel is easily etched by chemicals and scratched by wayward aggregate. These surface blemishes are a home for water and freezing temperatures and hitchhiking aggregate that sticks to the can surface, causing wear and tear to the belt itself.

Innoveyor, Inc. now offers a line of titanium-enriched PVC (polyvinylchloride) idler drums. These heavy-duty, lightweight rolls, branded YeloRoll due to their col-our, offer a number of features and benefits, especially during winter months when conventional steel can rolls can bring down a production line with every dip in ambient temperature.

The t-PVC-based YeloRoll exceeds CEMA D standards. In snow and ice, this unique roller design prevents build-up that will damage the belt, slow productivity and eventually bring production to a halt. Its smooth, non-porous surface rejects the graining and abrasion of steel can rolls. And it won’t rust or corrode.

These same issues are avoided year-round with the YeloRoll, which also rejects caustic and corrosive materials being transported by the belt. YeloRoll maintains a smooth, non-stick surface that also prevents belt misalignment in any weather condition. YeloRoll offers a 250 percent longer shell life.

The heart of the working end of all YeloRoll rolls is a high-quality, double-sealed, self-lubricating ball bearing system. Unlike the taper bearings used in conventional steel can rolls, this runs smoother, cooler and 55 percent quieter. Its carbon-fibre Combi-CapT aids in reducing noise as well as the shock and vibration encountered in steel can systems. Unlike steel can systems, YeloRoll’s unique t-PVC shells from Innoveyor are insulators, protecting against the transfer of heat and cold and thus condensation at the inner-working components, while at the same time, reducing and actually preventing the risk of fire.

These same inner components are kept clean and dry through the use of YeloRoll’s Combi-CapT system that protects the shaft ends. Its triple labyrinth seals keep dirt and other debris away from the roll and its critical inside components. Technician-friendly, even more so during the cold winter months, YeloRolls weigh 60 percent less than comparably-sized steel can units.
