Working principal

This thickener consists of round thickener and harrow scraping machine, the solid particles suspend in thickener settling by gravity, the pulp in the upper turn into clean water, so that the separation can be realized. Slime that sediment in the bottom of the thickener is discharged by the harrow scrapping continuously, and clean overflow from the upside.

Characteristics

  • 1. Deaeration cell is provided to avoid bobble on which solid particles may attach and settls as “parachute phenomena”.
  • 2. The mineral feeding pipe is beneath the liquid surface to provent air to be brought in by feeding.
  • 3. Inner overflow weir is equipped to let slurry flow on pre-designed route, avoiding “short circuit”.
  • 4. The pattern of the overflow weir is made into indented shape, eliminating suction phenomena in some part of draining induced by unleveled overflow weir.
