Genox underwater pelletising system able to process extensive range of plastics.
Over 300 companies in Australia have Genox recycling equipment installed, making it one of Australia’s leading manufacturers of recycling machinery.
The company is perhaps best known for its focus on providing the latest recycling technology at an extremely competitive price point, empowering large and small companies alike to achieve their environmental KPIs and actively contribute to the true circular economy. Genox’s range includes stand-alone shredder and granulator units, automatic metal and tyre recycling systems, through to complete washing plants for size reduction, washing and separating of contaminated plastics and other materials.
The company’s latest innovation is the SPS Series Pelletising System: a 3 in 1 integrated system that includes plastic waste size reduction and filtering, pre-heating and underwater pelletising.
The innovative design allows for an extensive range of soft plastics and rigid flakes plastics to be processed. This includes LDPE packaging film, agricultural film HDPE, milk bottle flake, PP bottles and plastic flake recovered from e-waste. The SPS system is especially efficient and stable for low-bulk density materials.
The variable speed cutter compactor (with air-flush) cuts the plastics into flakes. Heat created by high-speed friction pre-heats and dries the material and makes it shrink. Arc-shaped plates guide the material down into the extruder under the centrifugal force of the knife disc. Thus, size reduction, pre-heating and compacting is combined and this enables stable and effective feeding of small bulk density plastics.
One of the most innovative aspects of the SPS Series is the self-cleaning laser filtration system which allows for non-stop recycling extrusion – making it especially suitable to highly contaminated materials and high throughput applications.
Different from traditional screen changers – which requires the dirty wire mesh to be continually changed – the SCF system provides continuous filtering performance removing contaminates from the surface of the steel screen plate automatically, thus saving time and reducing labour costs.
A two stage (triple venting) extrusion process with vacuum degassing is utilised. The pelletiser cutting speed is automatically adjusted according to the melt pressure at the die head to ensure uniform pellets. Pressure of the blade onto the die is automatically adjusted to ensure even cutting force by a high-precision pressure sensor.
“The Genox SPS Series is a true underwater pelletising system which allows for a far greater range of materials to be processed including high-melt index PP grades,” said Applied Machinery’s Sales Manager of the Recycling Division, Peter Koueik.
The final step in the process makes use of an advanced de-watering vibrating sieve combined with a horizontal centrifugal dryer. This high-efficiency low-cost drying system uses precise temperature control and an optimised plasticisation design to ensure a high-quality consistent pellet size. A single stage or two stage pelletising system can be specified.
The system can be started and stopped by one button to protect the system from any inadvertent commands. Shutdown safety switches are located along the line wherever rotating blades are in operation to always ensure operator safety.
“Until now, underwater pelletising and self-cleaning laser filter systems were simply not available on complete lines at this price point,” Koueik said.
“For a short period companies can take advantage of special launch pricing as we introduce these systems to the Australian recycling market,” he added.
“Unlike many other machinery suppliers we don’t just sell machinery; one of our key advantages is that we have specialist service engineers who install the machinery and train our customers and their staff to use it efficiently and safely. We then provide regular servicing and follow-up,” Koueik concluded.
