Eriez New RevX-E Eddy Current Separator Design

Eriez Rev-X Eddy Current SeparatorEriez has announced a new magnetic rotor design for their RevX-E eddy current separator, the most recent addition to their extensive line of recycling equipment. The new design of the eccentric magnetic rotor brings the greatest recovery of valuable non-ferrous metals for a wide range of applications.

Resulting from extensive research and development, the Eriez eccentric rotor design offers the highest performance on the market in terms of material displacement and reliability. The new eddy current rotor has been proven by independent third-party testing to throw aluminum ‘fines’ nearly 20% farther than the leading supplier of eccentric eddy current separator. This ensures a high recovery of valuable metals that would normally go to landfill as well as allowing the end user to have a high-grade metal product.

The new eddy current separator design features a smaller diameter magnetic rotor offset at the top of a larger outer shell. The strong eddy current then repels the non-ferrous parts (aluminum, copper, brass, zinc) with maximum efficiency whilst allowing the release of ferrous particles from the belt. This is critical to ensure that the eddy current separator remains reliable.

The change in rotor design and overall improvements in the Eriez RevX-E eddy current separator creates several advantages and benefits such as:

  • Rare Earth rotor produces a powerful focused field, allowing greater recovery of non-ferrous metal
  • Rotor position is adjustable for optimum separation
  • Eccentric design reduces long-term wear from ferrous accumulation on the belt
  • Compact design requires less space and is easier to install in most plant operations
  • Access panels are conveniently located for easy servicing.

Eriez manufacture two styles of eccentric eddy current separator, one for fine material typically smaller than 25mm and a second unit designed for more coarse material over 25mm and up to 150mm. Although the selection of eddy current separators depends on a number of factors such as product size, percentage of conductive material, product temperature, throughput of the machine, etc, Eriez’s experienced engineering team work with the recycler to ensure the most efficient is specified for the application.

Eriez has captured high-speed and close-up images of the new eddy current separator in a video (see below). The video showcases how the eddy current separator removes aluminum, brass, bronze, copper and other metallic from the post-consumer PET stream. Watch the high launch speed and trajectory of the eddy current separator as it removes nonferrous materials from the bottle recycling process.
