Astec’s Prosizer 2514MF is a more compact version of the portable crushing and screening plant than its predecessors.
MODIFIED AND IMPROVED:
ASTEC PROSIZER IT’S BEEN A MAINSTAY OF THE AUSTRALIAN PAVEMENT AND AGGREGATE RECYCLING SECTOR FOR OVER A DECADE. NOW, ASTEC’S PORTABLE CRUSHING AND SCREENING PLANT HAS GONE THROUGH A MAKEOVER FOR AUSTRALIAN CONDITIONS, WITH BENEFITS FOR BOTH OWNERS AND THE ENVIRONMENT.
T
he portable ProSizer plant by Astec is no stranger to the Australian construction landscape. It has been recycling aggregates and asphalt solutions here for more than a decade. The ProSizer has also been applied in the pavement recycling sector, where it is used by road profilers and asphalt producers to process reclaimed asphalt pavements (RAP). The ProSizer – named for its “product sizer” application – incorporates a horizontal shaft impact crusher and screen on a portable chassis and trailer. Traditionally, the ProSizer has been available in three models – the ProSizer 3100, 3600 and 4200. The average dimensions of each of these models is around 20.4m x 3.4m. Last year, Astec Australia launched a compact version, the ProSizer 2514MF. At
only 17.56 metres, the 2514MF is almost three metres shorter than its predecessors. As Astec Australia Business Line Manager – Materials Solutions Adam Gordon explains, the redesign was part of Astec’s strategy to make the plant more easily transportable across every state and territory. “The new Astec ProSizer is a result of collaboration between the Astec Australia team and the manufacturing team in the US, taking in feedback from our clients and also factoring in considerations for Australia’s road transport regulations,” Gordon tells Roads & Infrastructure. “The original ProSizer was a good machine and is still suitable for the US market. But over the years, there have been more regulations imposed by different states in Australia, which made it difficult to tow the plant cross-country. With many kilometres of
spray sealed roads in Australia, we identified an additional benefit by minimising the overall trailer length to reduce any potential risk of damaging the sprayed seal surface when turning sharply. For all these reasons, we knew it was time for a redesign,” he adds. HIGHER PRODUCTIVITY For the pavement recycling industry, in particular, the 2514MF delivers benefits. As Jorge Boil, Astec Australia’s Business Line Manager – Infrastructure points out, the more compact design allows smaller asphalt producers to increase their economic returns by transporting the ProSizer from one project site to another. “A big problem with having a fixed plant is volume. Because the 2514MF is easily relocated, it can work across multiple sites roadsonline.com.au
