All machines get a test run before shipment at bomatic site. Even if, as it was in this case, only cutter modules are in scope of supply, the machines will be built up completely and tested. The described machines are used for shredding of complete filled files and the material will be shred in two steps. The cutters, which are produced in bomatic workshop, are exactly designed for the shredded material. The first machine contain cutters with small height of cutter knives, the second machine thin granulation cutters. The possibility of manufacturing the cutters in bomatic workshop allows us to design and produce cutters, which are exactly defined for the material – a big advantage for our customer.
