Frequency inverter for shredder: Operating smoothly under full load and efficiently under partial load!
Frequency inverters for the shredder motor of a metal recycling system ensure that the motor operates in the optimum power range. This results in a gentler metal recycling process at full load and higher efficiency at partial load compared to operation without a frequency inverter.
As a result, the following major challenges in shredder operation can be overcome:
- Consistently high power consumption: Operating the shredder requires consistently high power consumption to cope with the highest load at start-up, for example. This is reflected in the costs.
- High load peaks: The powerful drive of the shredder motor leads to high load peaks when operating without a frequency inverter, which can result in significant penalties to the energy supply company and, in the worst case, an unstable electricity distribution grid.
- High mechanical wear: The operation of the shredder causes high wear on the mechanical parts.
Frequency inverter for the shredder drive saves 7-10% electricity costs
Where a lot of electricity is needed, a lot can also be saved. Frequency inverters enable the speed and torque in the shredder to be adjusted to the actual demand, so that the drive runs in an energy-optimised manner even under partial load.
In addition, the devices themselves are optimised for the lowest possible energy consumption, which significantly increases the energy efficiency of systems.
The use of energy-saving inverter solutions from Mitsubishi Electric for the main motor of the shredder reduces energy costs by 7-10%.
// Saving 7-10% energy costs in the process
// Adaptation to load requirements
// Energy efficiency even at partial load
Frequency inverter reduces peak loads when driving the shredder
Frequency inverters enable controlled acceleration and deceleration of the motor. This means that the motor does not start or stop immediately at full power, but the speed is gradually increased or reduced.
A smooth start and stop of the machine avoids high consumption peaks and expensive grid faults.
In a failure-critical process such as metal recycling, high costs due to machine downtime can therefore be avoided. In addition, high load peaks can lead to penalties for the energy supply company, which can be avoided.
// Reduction of expensive consumption peaks
// Avoidance of penalty payments to energy supply companies
// Ensuring grid stability and reducing the risk of failure
Frequency inverters for the shredder drive increase the life time of the recycling system
Frequency inverters make a significant contribution to extending the life time of motors and mechanical components. Mechanical systems such as gearboxes, couplings and drive shafts are susceptible to heavy loads caused by abrupt load changes.
Frequency inverters, on the other hand, enable smooth starting, precise control of speed and torque and offer other important protective functions. Their ability to control motor speed changes smoothly and continuously effectively prevents shock loads. This results in less mechanical stress and reduces maintenance costs.
// Increase the service life of mechanical elements
// Less system downtime due to maintenance and repair
// Lower maintenance costs
The perfect frequency inverter for your metal recycling shredder
Depending on the required voltage, the FR-A800 series of low-voltage frequency inverters or the TMdrive medium-voltage frequency inverter are particularly suitable for the optimum operation of motors for shredders.
Our FR-A800 series frequency inverters offer high drive precision and fast speed control
Medium-voltage frequency inverter TMdrive for high power
TMdrive combines compact design with high efficiency and performance. For medium voltages in the 3.3-11 kV range, it achieves outputs of up to 7,350 kVA and ensures grid-friendly operation with a maximum harmonic distortion of two per cent. It complies with the IEEE-519 standard for mains harmonics. The energy recovery function also saves energy costs.
