Van Beek, Drunen, the Netherlands, reports that Veolia Polymers in Vroomshoop has been subjecting its screw conveyors to the ultimate durability test for over two decades. The screws operate day and night to transport and homogenise plastic grinding stock. Van Beek has recently overhauled dozens of its own screws in the plant. The screws that Van Beek replaced had been amortised a long time ago. "We have made the replacement interval as long as possible and so they went on operating long after being written off”, explained Peter Verhoeven, sales engineer at Van Beek.

 

The new screw conveyors offer a number of attractive improvements compared with the ones installed more than a decade ago. "In recent years we have gone even further in the wear-resistant direction. A few critical parts have been improved so the screw conveyors last even longer ", explained Verhoeven. The screw conveyors are used mainly to homogenise and transport plastic grinding stock. The plant makes small granules here for injection moulding. The screw conveyors transport the granules to giant mixing silos with a screw in the centre to homogenise the granules. From the mixing silo another screw conveyor transfers the granules to a dosing unit above an extruder. www.van-beek.nl
