Erdwich EKZ machines are characterised by their robustness and reliability, resulting in very long service lives in application. Such shredders are often in operation 24 hours a day and are subject to the highest stresses. Easy maintenance of the cardboard shredders, especially due to low-maintenance chain drives and individually bolted, replaceable feed and ripper segments, result in low operating and maintenance costs. The EKZ is also characterised by its variable application options. The cardboard ripper is available in horizontal as well as vertical versions and with different cutting gear lengths. This means that it can be used for a wide variety of carton shapes and sizes. The horizontal version is perfect for manual feeding by hand and the vertical version is ideal for continuous feeding via a conveyor feed system, etc. The cardboard shredder is available in cutting gear lengths of 1,100 mm, 1,400 mm, 1,800 mm and 2,500 mm and can achieve average throughputs of 1,000 - 1,500 kg/h for cardboard materials. In addition to these different variants, there are also different blade shapes, one in a scale shape and one in a star shape. Depending on the material and carton shape, the feeding characteristics of the shredder can be individually optimised. The result of the shredding is pieces of different sizes and shapes. An exact final grain size cannot be defined. In addition, this type of machine is perfect for implementation in a company´s already existing processing lines and can be integrated according to the Industry standard 4.0 incl. complete automation methodology. An integrated PLC automation with reverse and automatic cut-out is standard in the switchgear of the EKZ shredder.
