Waste Management Review touched down in Sydney in August to attend the Australasian Waste & Recycling Expo and visit numerous resource recovery sites. Toli Papadopoulos reports.
Polystar’s technology addresses the issue of plastic recycling by offering a range of one-step machines designed for the reprocessing of polyethylene and polypropylene flexible packaging material.
Polystar machines are designed to be simple to operate and easy to maintain, all the while taking up minimal space and time. Their output comes in the form of high-quality plastic pellets that can be fed straight back into the manufacturing process, saving on raw material costs as well as on waste disposal.
This pelletising system – with its integrated cutter compactor – eliminates the need for pre-cutting in most cases and ensures the material spends less time in the extrusion process to minimise degradation. This means that the final product will be of the highest quality and the material properties will not be affected.
In addition to the double degassing in the first extrude, the venting area – the connection between the first and second extruder – serves as a third degassing section (optional) to further remove the ink and extra humidity level from the material.
The unvented extruder has a very short screw L:D ratio, in which the material travels in the extruder for the shortest time and distance. This results in minimal change in material property and higher output comparing to vented extruder.
Furthermore, the re-positioning of filtration before degassing ensures a superior degassing effect, producing high quality pellets from heavily printed material.
Applied Machinery Managing Director David Macdonald said manufacturers who want an easy, efficient solution to plastic film recycling now have the opportunity with Polystar recycling machines.
“Polystar requires less space and energy consumption whilst producing high quality plastic pellets, which are immediately reusable. The Polystar machines are a must get for companies that are serious about plastic film recycling,” Mr Macdonald said.
Polystar is a Taiwanese-based company that now has machines operating in 102 countries.
“Applied Machinery is proud to have been appointed a distributor for Polystar machines. We are confident that the product will appeal to manufacturers looking to effectively recycle their plastic film waste, and provide those manufacturers with a competitive advantage in the market place,” Mr Macdonald said.
Applied Machinery recently celebrated 25 years in business and, in addition to Polystar, represents a large range of other premium machinery manufacturers including Yawei, Genox, Hurco, Cosen, Chen Hsong, Alfarobot, Hermle, Akyapak, Pro-Plas, Hyundai-WIA and Kitamura.
The versatile Genox Vision Series Single Shaft shredders can be used in a range of challenging applications, including plastics, timber/wood, paper and cardboard, copper, aluminium, textiles and foams.
Standard features include a v-cutting rotor design with staggered cutter positioning and heat-treated rotor knives. Long life, adjustable fixed blades ensure cutter clearance can be maintained. Rotor speeds operate at 80 revolutions per minute across the V500, V600 and V800 models, with throughputs ranging between 300 to 5000 kilograms per hour, depending on the machine model, material type, screen size and application.
A classifier screen allows for accurate control over the particle size, in addition to a force-feeding ram with a segmented shredding chamber floor.
A powerful driving system includes shock absorption to reduce stress on drive performance. The rotor is equipped with multiple knives to shred the material against counter knives. In addition, dual speed hydraulics allows for a fast return of the ram to maximise throughputs.
Shredder settings are customisable via an electrical control panel, which features a standalone control cabinet, dual mode operation and intelligent programming to assist during overload scenarios and auto-shutdown.
Equipment from Genox Recycling Technology is available in Australia exclusively through Applied Machinery, with a machine distributed for practically all size reduction and recycling applications.
