DYNA Engineering has introduced new HDPE rollers to meet the growing demand for sustainable, long-lasting rollers.
DYNA Engineering is no stranger to high density polyethylene (HDPE). The company has been using the relatively lightweight and durable material for several key products, including conveyor guards and protective guarding on underground shotcreting plant.
Mine sites across Australia have also seen the benefits of swapping from steel to HDPE. Not only are HDPE rollers significantly lighter than their traditional steel counterparts resulting in energy savings and improved productivity, but they also require no surface treatment, are quieter, and require less downtime.
DYNA Engineering general manager Thomas Greaves said this makes them an appealing package for any mining company or contractor interested in greater productivity, reducing downtime and minimising safety risks for maintenance and operational people.
To meet the growing demand for more sustainable, quieter-running, longer lasting rollers, DYNA Engineering has developed composite rollers that make use of glass fibre reinforced high-density polythylene (GRHDPE)
Greaves said these rollers are better able to handle the harsh conditions commonly experienced by mining companies struggling to keep up with today’s increasing requirements for more sustainable and effective conveying of ore over longer distances.
He added that it was a “quiet and important success” for DYNA’s GRHDPE rollers when a valued customer in the far north of WA’s Pilbara rolled them out on site.
“We have complete confidence in the performance of our GRHDPE rollers. The Pilbara is a harsh and testing region of the world, but due to our extensive quality systems and experience in design manufacturing conveyor equipment, we know they are built to last in such trying conditions,” he said.

“We’re now in full production as the news gets out and the orders are coming in” he added.
Shell materials offered in DYNA’s roller range now include steel, stainless steel, aluminium and the new HDPE and GRHDPE Composite. They can be customised to suit almost any requirement including bearing brand, bearing size or series, and project standards and specifications.”
The company continues to offer many other types of rollers such as impact, rubber, coated rubber, screw, steel screw, and rubber disc. HDPE options are only available on plain rollers at this point.

One of the benefits HDPE rollers provide is significantly quieter running. This can be very important when conveyors operating near built up areas continuously through day and night can cause discomfort to nearby residents.
Up to 10dB less operational noise than steel rollers could even mean the difference between a new land traversing conveyor being built and put into operation or not even getting approval to proceed in some cases.
“This latest addition using HDPE to further widen our range of conveyor componentry is concrete evidence that our decision to significantly invest in the design, development and manufacture of more HDPE products back in 2018 was definitely the right way to go” Greaves said.
“We have every intention of continuing to go down this path. All of us here at DYNA are genuinely pleased to see such progress and innovation in the conveyor space” he said.
