Shredded process waste from corrugated board processing can be easily transported and prepared for recycling. Shredding takes place either directly at the die-cutters and machines or by means of a high-performance shredder that shreds the output from several machines to a transportable size.
Edge trim can be easily shredded using edge trim fans. The processed material can be transported via conveyor belts or pneumatically to the baling or container presses for optimum recycling. Höcker Polytechnik offers suitable shredder solutions for all these applications or integrated disposal concepts, including sorting, for the entire production process.
Bulky materials, sheet goods, cardboard packaging or robust core tubes block valuable storage space and can only be fed into the company’s internal disposal workflow with a great deal of effort. Shredders from Höcker Polytechnik also provide support here, recovering valuable storage space, increasing recycling revenues and continuing to keep the company’s own waste disposal centre tidy.
The manually operated PHSH shredder from Höcker Polytechnik can shred up to 8,000 kg of material per hour into handy, easily transportable pieces. The shredded material is then fed to an existing disposal line either via conveyor belt or via an extraction hood and can be prepared for pressing. In order to cope with such large quantities of material in everyday working life, 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, where 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 – saving time and increasing throughput.
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 robust PHS and PHSH shredders have been used hundreds of 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. Thanks to the robust welded construction, the components designed for durability and advantages such as space-saving and safe storage of the shredded material, higher recycling proceeds and reduced labour costs, the investment in such shredders often pays for itself within a few years.
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. These Höcker Polytechnik shredders are ready for Industry 4.0.
