Eirich, the pioneer in material processing technology, has reinvented the way mixing is approached by using technology that allows for the recycling of wet and oily metallurgical waste. Birkenmayer, process engineering specialists and the sole representatives of Eirich industrial mixers and processing units, is able to distribute this expertise throughout the South African market, with the support from Eirich and its partners from across the globe.

Traditional industrial mixers are only able to easily handle dry material and do not allow for variable mixing ratios. Due to the high cost of drying, it is uneconomical to recycle wet metallurgical waste using these systems. The waste has further financial implications with the cost of dump and storage management, as well as the loss of iron units, or other expensive raw materials.

“Eirich industrial mixer technology delivers outstanding micro-mixing results that allows for flexible mixing ratios and the ability to process dry, wet, oily or fine materials quickly and evenly,” says Louis Eksteen, Business Development Manager, Birkenmayer.

The Eirich industrial mixers’ system consists of just three components. The way in which these components are used can be varied to suit the customer’s requirements:

  • The rotating mixing pan delivers the mixture into the area of the mixing tools
  • One or more mixing tools are arranged eccentrically, which creates a counter-flow with optimised differences in speed
  • The stationary scraper tool provides a vertical component in the mixture, which prevents material build-up

“In order to produce high quality end-results, you need to have a constant and stable input. This is difficult to achieve with recyclable materials as you do not always know what goes into the batch,” notes Eksteen. Eirich industrial mixers optimise the agglomeration process by evening out the batch instability and mixing the input thoroughly. The process produces a constant and stable mix.

By using the recycled material, customers have the ability to use in-house and outside waste, which could ultimately mean a reduction in their input costs. The process also has ecological implications, while still making economic sense.
