THE successful penetration of polymer rollers as replacements for traditional metal rollers on conveyors has highlighted a new question -- are the rollers recyclable?
"Yes most definitely," says Neil Kinder, director of Kinder & Co .
Even though the rollers are made of composite materials, these can be separated and shredded to be put into the recycling chain to produce, for example, fence posts as an alternative to CCA treated posts. The rollers do not contain PVC which is considered toxic and carcinogenic.
Due to the lightweight construction of the product compared with steel, the new generation K-Polymer conveyor rollers are said to be much safer for manual handling and installation, particularly along conveyor inclines.
Considering that the Federal Government's Department of Employment Workplace Relations has publicly stated that back injuries account for about one third of all workers compensation costs and one third of all workplace injuries, site managers see lighter alternatives as a major benefit.
They are also quieter with field reports showing a 10dBA reduction in noise emmission.
Because the roller is 50% lighter than steel the rollers draw less energy. Rim drag is also low so savings can be made in the actual running of the conveyor. In terms of efficiency they are "New Generation".
Mr Kinder says the lighter properties of this new generation release of polymer rollers further reduces prospects of the archaic habit of employees lugging steel rollers up steep conveyor gantries and then manoeuvring them under structures into awkward positions.
"As the technology is light, maintenance crews can position them with far greater ease and with less risks of personal injury," Mr Kinder said.
"But they are also robust - a truly heavy duty alternative to the steel shell roller and just as tough.”
