Shredder Technology –
Variable Frequency Drive (VFD)
The high-performance VFD continuously monitors and controls rotor speed in real time. When heavy material causes temporary speed reductions, the system quickly restores optimal rotor speed, ensuring consistent shredding performance, improved energy efficiency and reduced mechanical stress.
Combined with the LINDEMANN Shredder Drive Assistant (SDA), the VFD creates an intelligent drive system that synchronises material feeding and rotor performance. The result is higher throughput, lower energy consumption and improved equipment availability.
Benefits of VFD Technology
-
Increased processing capacity
-
Higher throughput rates
-
Improved ferrous and non-ferrous scrap quality
-
Expanded WEEE recycling capabilities
-
Reduced maintenance requirements
-
Enhanced energy efficiency
-
Greater process control through variable rotor speeds
Benefits of the Medium-Voltage Concept
Compared to conventional low-voltage drive systems, the LINDEMANN medium-voltage concept offers exceptional grid stability, reliability and efficiency. The system effectively handles voltage dips, flicker and load peaks, allowing full-capacity operation even on weaker power networks.
The LINDEMANN VFD system maximises throughput, energy efficiency and machine availability, helping operators achieve more productive and sustainable metal recycling operations.
Additional advantages include:
-
High starting torque without inrush current peaks
-
Reduced motor and drive energy losses
-
Low maintenance requirements
-
High efficiency and operational reliability
-
Very low harmonic distortion and improved power quality
