General description

The 457 mm diameter rotors ranging from 850mm to 2000 mm width are driven by either one or two oversized gearboxes. The hydraulic power pack is well integrated into the machine housing to save space and protect it from damage but is still easy to access or remove for maintenance.

The standard E rotor features the proven ZERMA knife and knife holder design, as well as outboard bearings and a hydraulically operated screen cradle. The machines can be tailored to various applications and is offered with rotor cooling, hard facing and other wear options.

The ZPS shredders have been designed for a wide range of applications and industries such as in-house and general recycling, electronic waste and post consumer waste handling. Input materials can be all types and forms of plastics such as lumps, pipes, film, bales, woven bags; electronic waste like cables and ICBs, paper, wood and other organic materials.

Depending on downstream requirements, the shredded material, with size defined by the fitted screen size, can be used directly or can pass to the next stage of size reduction, for example a GSH granulator.
