Bay Plastics’ Gearbox-Free Drive Solution Modernizes Pelletizer Feed Rollers
A new belt system for driving upper feed rollers (UFR) without a gearbox has been announced by pelletizer provider Bay Plastics Machinery.
The new option can be readily installed on existing pelletizers or purchased with new Bay pelletizers, eliminating the noise and maintenance associated with a gearbox.
The UFR belt drive is designed to be installed on single- and dual-drive pelletizers or retrofitted to existing pelletizers of multiple configurations. Similar to a normal feedroll serpentine, the UFR belt is detensioned for quick pelletizer access when the chamber cover is opened. And, new machinery can be narrower than the width previously required when using a gearbox – in fact, the same width as a standard, non-gearbox design.
To use this system with current pelletizers, customers just have to order new extended- shaft upper and lower feed rolls with a conversion parts kit containing bracketry, belt, idlers and a tensioner; then install the parts and put on the drive belt, explained Bay’s President Jason Forgash.
“Customers will only have to drill and tap a couple of mounting holes to retrofit their existing units, if the holes are not already there” Forgash said. “We’ve been including the mounting holes with every new pelletizer delivered for some time now, the entire conversion only takes a few moments.”
Benefits of Bay’s belt-driven upper feed roll system include:
- A controlled gap between rolls when running steel upper and lower feed rolls.
- Greatly improved ease of startup when running a gap between rolls.
- More consistent pulling force with difficult-to-pull material.
Additionally, operators can run a steel upper feed roll when running high-temperature materials. The system saves money by using readily available components, not costly custom gearbox parts and U-joints – many with lengthy lead times.
