PLASTIROL from the Dutch town of Sliedrecht is a manufacturer of plastic foil produced in large rolls. For their raw materials, which are recycled from production waste, in the past they used bulk bags. This usually caused many storage, handling, discharge and replacement issues in their internal logistics system. The move towards larger storage silos linked to a vast duct network became mandatory.
Rather than through bulk bag handling using forklift trucks, materials are now transferred via a pneumatic conveying system, from the shredder directly into the mixing silo. From the mixing silo the plastic flakes are conveyed throughout a network of 150 mm diameter duct pipes into eight storage silos. To divert the material inside the duct network, PLASTIROL chose pneumatically operated VAB-type Diverter Valves by TOREX®. Due to rather awkward accessibility inside the building, the customer preferred an outdoor installation of the duct network on the roof of the building.
Thanks to the VAB Diverter Valves, silo filling operation has become fully automatic. For PLASTIROL this means reduced costs for storage, handling and labour.
