Heavy fractions:
- stones
- bricks
- bottles (plastic, glass)
- cans
- other heavy items
A solid, inclined screen plate that oscillates sets the material on it in motion. Heavy and spherical or cubic parts roll down into the heavy fraction, which includes unwanted debris – such as stones, bricks, and other heavy items – that have to be removed in order to protect the downstream equipment in a reject line. Furthermore, this fraction includes very valuable compounds, such as plastic bottles or cans. All flat and light particles – such as plastics, sheets of paper – move upwards towards the light fraction. The screen plate (sieve) creates a fine fraction.
The ReBal can process wet material (with consistencies down to 20%) and has a high throughput of up to 60 m³/h. The machine is manufactured in-house and has already been applied in several reject lines supplied by ANDRITZ.
