Metal Recycling

Frequency inverters for the shredder motor of a metal recycling system ensure the motor operates within its optimal power range, resulting in a smoother recycling process under full load. They also deliver significantly higher efficiency during partial load operations compared to systems without this technology.
This advanced solution helps to solve the major challenges in shredder operation such as: consistent high power consumption especially during start-up, high load peaks such as potential risk to grid stability and excessive mechanical wear which shortens the lifespan of essential components.
Implementing frequency inverters not only enhances energy efficiency but also reduces operating costs and prolongs the durability of the equipment, making it an indispensable upgrade for modern recycling facilities.

Where energy demand is high, there’s also great potential for savings. Mitsubishi Electric frequency inverters let you adjust the speed and torque of your shredder to match actual load requirements, ensuring the motor runs efficiently, even at partial capacity.
These inverters are designed to minimise energy consumption, significantly enhancing your system's overall efficiency. Optimising the performance of your shredder's main motor can lead to energy cost savings of 7–10%, making a significant difference to your operational budget.

Choose Mitsubishi Electric's energy-saving solutions to cut costs, adapt seamlessly to varying loads, and maximise energy efficiency at every stage of the process.

Traditional systems, such as gearboxes, couplings, and drive shafts, often endure heavy wear and tear from sudden load changes.
By enabling smooth starts and precise control of speed and torque, frequency inverters prevent abrupt shock loads that can strain your equipment, in particular the motors and mechanical components. This not only reduces mechanical stress but also minimises maintenance needs, leading to lower costs and less system downtime for repairs.
Frequency inverters make your systems more reliable, lengthen their lifespan, and reduce costs.

Depending on the required voltage, the FR-A800 series of low-voltage frequency inverters or the TMdrive medium-voltage frequency inverter are particularly well-suited for the optimum operation of motors for shredders.

Power range and technology
The frequency inverters in the A800 series cover a power range from 0.4 to 500 kW. With the help of advanced technologies such as ‘Real Sensorless Vector Control’ and ‘Online Auto-Tuning’, optimum torque and speed control of the drive is always achieved. These technologies ensure precise and efficient control that meets the requirements of a wide range of applications.

Robust and reliable components
The A800 series is equipped with robust and reliable long-life components, such as high-quality capacitors. These make the devices ideal for demanding industrial applications where durability and reliability are crucial.

Operating temperature and vibration resistance
FR-A800 series frequency inverters can be operated in a wide temperature range from -‍10 to +‍50 degrees Celsius. They are also characterised by a high vibration resistance of maximum 5.9 m/s², which enables them to be used in harsh environments.

Predictive maintenance
An outstanding feature of the A800 series is the predictive maintenance function. This prevents unplanned machine downtime by continuously monitoring the condition of the devices and signalling maintenance requirements at an early stage. This maximises uptime and increases the reliability of the entire system.
