Bad Marienberg, Germany-based Vecoplan AG has unveiled its VRZ series preshredders for processing domestic and commercial scrap, promising efficient, yet low-maintenance operation to break up and shred bulky materials.
The company says it placed emphasis on a rotor that combines sickle-shaped ripping teeth for safer operation that also can shred materials laden with extraneous items, such as minerals or nails, powered by its HiTorc drive. Unlike cutting tips in other machines, the VRZ’s ripping teeth are armored.
“[Vecoplan development specialists] have created a machine that is not only resistant to extraneous items but is also robust, reliable and low-maintenance,” Recycling-Waste Division Head of Application Technology Cathrine Rekett says. “Rearmoring the ripper teeth when they’re worn is more time-consuming than changing cutting tips and counter knives, but their running times are much longer. The bottom line is that this significantly reduces downtimes.”
The torque drive has no mechanical components, such as belts, clutches or hydraulic units, which Vecoplan says leads to less maintenance than hydraulic drives. The company adds that the HiTorc drive can achieve a high efficiency level because there is less mass to be propelled, saving energy costs. The drive’s output is 2x138 kilowatts.
“During development, we wanted to keep operating and maintenance costs as low as possible for the plant operator,” Rekett says.
Components such as wear-resistant and replaceable sealing elements at the rotor and side wall prevent materials from becoming lodged between the front surface of the rotor and the machine housing. Vecoplan says its optimized design means the cutting frame and rotors can be replaced quickly and time-consuming maintenance, such as reinforcing welding work, can be performed outside the machine, reducing downtime.
“Our VRZ is designed to remain operational for as long as possible, even if wear does occur,” Rekett says.
Vecoplan says its VRZ 2500, for example, has an open cutting table that allows stones and other extraneous materials to fall through the cutting unit without shutting down the machine, and that extensive practical tests with different materials have shown successful continuous operation.
The VRZ series has a modular design, and customers can choose from several options to configure their machines, such as various cutting units like cutting tables and rotors that can be easily replaced to adjust the VRZ to a specific particle size or usage scenario.
