M&J Recycling's electronic fine shredder for RDF and SRF production

The new, energy-efficient F320 E-drive from M&J Recycling is designed to deliver enhanced refuse-derived fuel (RDF) and solid-recovered fuel (SRF) output of up to 28 tonnes per hour. The electronic fine shredder has the same power as its hydraulic counterpart, but is significantly cheaper to run and much quieter.

The task for M&J Recycling's development team was clear from the start when they set out to produce an electronic fine shredder for heavy production of RDF and SRF. All the familiar qualities of the company's hydraulic fine shredders were to be retained 1 to 1 in the new M&J F320 E-drive, resulting in the same capacity output, the same stability, and the same durability. The M&J F320 E-drive performs fully on par with the hydraulic version, and has a number of advantages.

The M&J F320 E-drive uses around 20 percent less energy for production, which translates directly to the operating budget - especially as energy prices continue to rise. The E-drive solution requires a lower amperage on the main power supply due to smaller electric motors used in the driveline (160 kW motor instead of 250 kW). In certain markets, this results in a reduction of taxes for installed power connection.

"E-drive requires a minimum of service and wears out less than a hydraulic drive. There are fewer moving components in the drivetrain, and you don't need to supervise and exchange hydraulic components," says Jens Vestergaard Nielsen, head of R&D at M&J Recycling. "Together, this means that the customer can expect significantly higher uptime and significantly lower costs to keep the machine running."

In addition to budget savings, the electronic fine shredder also has automatic connection tothe service centre, saving response time and potentially enabling preventive maintenance. Additionally, the E-drive makes significantly less noise than a hydraulic drive due to the lack of large pumps.

The first M&J F320 E-drive has already been installed and is in use at a customer site. In preliminary tests, both power consumption and capacity meet all of M&J Recycling's expectations.
