Jan 25 2021 Read 598 Times When shredders have to work long and hard, Vecoplan relies on its proven HiTorc direct drive. A controller integrated in the frequency converter ensures that the optimum torque is available at the rotor shaft at all times and in all operating conditions. As a result, the drive is extremely energy-efficient. What is more, this purely electrical solution requires no clutches, belt drives or flywheels, which means that maintenance costs are significantly reduced. The HiTorc drive has proved itself over many years, giving Vecoplan a clear technological lead on the market. “We’re working at all times to satisfy the growing demands of the market,” says Martin Baldus, development manager for industrial shredding at Vecoplan AG. “We provide our customers with cost-efficient systems that give them long-term benefits.” Shredding is becoming an increasing challenge. “Our customers’ machines often run around the clock, sometimes seven days a week,” says Baldus. The shredders’ tasks include preparing material for the combustion furnaces in cement works and efficiently processing packaging made from plastic, metal and composite materials collected in bags. Household waste is another input material. Shredders can also process wood waste, used wood and root balls – material that is often contaminated with impurities. “Downtimes of these systems can be very expensive for operators,” adds Daniel Kessler, head of electrical engineering at Vecoplan. “The machines must therefore be robust, resistant to contaminations, reliable and low-maintenance.” The rotor drive is a key element. “We recommend dynamic, high-torque, quick-start drives in the HiTorc series especially to those customers who have continuous operation.”
