To cope with such large quantities of material, a shredder that is manually fed with material must also be designed for optimum ergonomics when feeding the material. The operator places the cartons on the wide conveyor belt of the PHSH shredder, which then automatically transports the material to the three shredder shafts. The two preceding shafts draw the cartons to the fast-running shredding shaft with cast iron teeth or a knife shaft with high-quality knives and shred them. Meanwhile, the next material can already be loaded.
Cores with a maximum diameter of 150 mm and wall thicknesses of up to 20 mm can be shredded in the integrated core cutter. The core is inserted, automatically drawn in and shredded. Shredded in this way, cores can also be disposed of via baling presses or container presses. If no core cutter is required, the PHS shredder offers the full range of functions, excluding the core shredder. The PHS and PHSH shredders have been used 100 times worldwide and are characterised by low wear and tear, and a design designed for safe working, with protection against interference at the infeed. The shredders can be flexibly configured and are available with different cutting widths and feed belt lengths.
In 2024, the PHS and PHSH shredders were technically revised, the range of functions was expanded and operation is now even more comfortable. The main functions can be conveniently set and controlled at any time using the touch panel. A further safety feature now prevents the side and maintenance doors from opening before the shafts have come to a complete stop. A modern PLC control system with an integrated OPC UA communication interface works in the background. The operating status of the shredder can thus be continuously transmitted to the company’s internal server environment and important information such as utilisation rates or unplanned downtimes can be easily retrieved.
