High energy costs
The recycling business is highly energy-intensive. Shredders, conveyors, and exhaust air treatment systems are massive electrical power consumers.
Changing power requirements
The rotor of a shredder must constantly adapt to changing power requirements due to the varying composition of the material being fed into the machine.
High load peaks and grid asymmetries
When the shredder rotor is loaded with metal scrap to be processed, it is temporarily slowed down. To compensate for this and bring the motor back up to speed, it draws as much power as possible from the grid, leading to load peaks, grid asymmetries, and high energy costs.
Therefore, new approaches are needed. Together with LINDEMANN Metal Recycling Solutions and Mitsubishi Electric, a system was developed that significantly reduces energy consumption.
