German company Herbold Meckesheim has designed a compact line for the treatment of toner cartridges. Using a belt conveyor with a hydraulic pushing device, material is transported to a shredder for coarse size-reduction. If necessary, metals can be discharged at this step. Material is subsequently fed into a slow-running Herbold SML-LS granulator which, due to its low circumferential speed, provides the final granular size of the material. With the help of a spiral conveyor, material is transported to a screening machine where the toner dust developed during size-reduction will be separated from the ground material. Since toner can provoke dust explosions, the machine has been equipped with a surveillance device. Ultimately, size-reduced material can be reused in injection moulding applications. According to the manufacturer, one of the advantages of the plant is that all the size-reduction and conveying steps use slow-running components, and so the plant operates at an extremely low noise level. This slow-running operation also limits dust development and affords considerably reduced wear in the relevant parts of the plant. The plant is also designed as a primary granulator for clean and sorted waste. According to the manufacturer, this can be a particularly economic option for abrasive materials such as glass fibre reinforced plastic waste. Conventional fast-running plants would not only create large material losses due to the development of dust-like particles, but also wear and tear in the granulator. In addition, pneumatic material discharge would be much higher, it is contended. Herbold manufactures plants of various sizes for the recycling of plastic waste, particularly in the medium to large range.
