Holzmag PreciCut shredder
For Bales and Loose Bottles
Oriental Recycling NV in Thurnhout, Belgium, has commissioned a new PET recycling plant from Holzmag AG Recycling Technology, Dornach, Switzerland. The core of the plant is the Holzmag PreciCut shredder, which can cut both compressed bales and loose bottle fractions into 60 mm granulate at output rates of up to 8 t per hour. According to Holzmag, the granulate contains minimal oversized material or fines. This makes it possible to color-sort the PET flakes and wash them without sludge formation due to fines. PreciCut shredding technology also allows a prewashing operation and the use of carbide plates in the tooling. The cutting surface of the knife block and the material rotation in the cutting zone are controlled by variable parameters for rotor speed/cutting frequency, contact pressure and the forward and backward speed of the material pusher. According to Holzmag, granulate size and quantity can be precisely adjusted to suit any downstream unit so as to permit direct feed without an intermediate silo. The purpose of the plant in Thurnout is to produce flakes for the manufacture of fibers used in the textile and carpet industries. For the moment, the flakes are still being exported to China, where they are processed into fibers and re-exported back to Europe.
