Modular sorting plant

The generation of concentrated fractions is an important step in the process chain of treating primary and secondary raw materials. In addition to the established classification and sorting processes based on physical principles there is an increasing demand for intelligent solutions to meet the growing complexity and heterogeneity of material flows.

In the process chain of processing primary and secondary raw materials, the production of enriched fractions from mixtures of substances is an important step. In addition to the established classification and sorting processes on a physical basis, intelligent solutions are increasingly in demand in order to cope with the increasingly complex and heterogeneous material flows.

Fields of application
The fields of application are diverse and range from the sorting of electrical scrap to the separation of mixed plastics by type. This creates the prerequisites for recycling appropriate to the material and increases the market value of the material flows.The modular concept comprises the following units in detail:

Multi-deck screening machine (flip-flow screen), Spaleck:

• Working width 975 mm
• Screening of difficult, sticky or wet materials with screen cuts from 0,2 mm up to
  approx. 50 mm
• “Trampoline effect” creates accelerations of up to 50 g in the screening mats
• Very good loosening up of the product, no clogging

Magnetic drum and eddy current separator, Eriez:

• Working width 1000 mm
• Particle size 1-50 mm (optimum ratio 1:3)
• Adjustment of process parameters through variation of rotation and belt speeds and positions of pass partition plates and pole wheels

Multi-sensor system, Sesotec:

• Working width 1024 mm
• Particle size 1-50 mm
• Combination of:
  - 2 CCD line cameras (color and shape of objects)
  - Induction sensor (detection of metals)
  - Hyperspectral camera (NIR 1330-1900 nm, identification of organic materials)
• Compressed air ejector:
  - 6,4 mm grid: 160 nozzles with 2,5 mm diameter
  - 3,2 mm grid: 320 nozzles with 2 mm diameter
