Light in weight, but not in results: HDPE roller for heavy-duty bulk handling

Rulmeca SUPREME roller is designed for a wide variety of applications where low noise operation and low energy consumption are researched while dealing with heavy-duty bulk handling and corrosive materials or environments.

It’s a completely HDPE roller, featuring high density polyethylene tube and housings (only rollers of > 600 length have a reinforcing steel tube fitted inside the HDPE shell). The ultra-tick polymer shell has a high strength-to-weight ratio, noise and vibration absorption properties, high resistance to abrasion and corrosion of the main aggressive contaminants and chemical agents. Add to that an additional static face and a labyrinth sealing system to further limit the ingress of dirt and provide a safety system to limit nip point risk. Also, the machined finish ensures low run-out and its self-cleaning surface prevents material spillage and belt miss-tracking.

Comparing our HDPE roller with normal steel rollers

Rulmeca SUPREME HDPE roller is able to handle the same loading capacity as a steel roller with equal dimensions. However, it has important operative advantages for the whole plant in comparison.

First, the polymer construction makes it about 50% lighter, therby ensuring easier handling and mounting operations, especially on large rollers. The resultant lower rotating mass also reduces the torque required for the conveyor, leading to energy savings during start-up, start/stop and continuous operations. Secondly, speaking about another sensitive issue in terms of environemnts and safety, high density polyethylene is able to minimize vibrations and absorb noise emissions in contrast to steel. Finally, the non-corrosive HDPE face means longer operating life and lower maintenance under aggressive conditions that steel is more vulnerable to. Our SUPREME roller is particularly suited to handling operations of abrasive sand, iron, gold, platinum ore, coal handling, indeed.
