The order matters more than the machines
Wheat cleaning follows a fixed logic: coarse before fine, dry before wet, size before density, and magnets always last. Reverse two stages and you either blind a screen or send stones into a roll. The sequence below is what every Haiyun flow sheet uses, from a 200 kg/h unit to a 500 t/d tower.
- 1 Intake & weighing
- 2 Coarse pre-cleaning
- 3 Size grading
- 4 Density separation
- 5 Surface scouring
- 6 Length grading
- 7 Wet cleaning (optional)
- 8 Dampening & tempering
- 9 Magnetic separation
- 10 Aspiration before break
