It is widely used for dealing with slime, wastewater, waste residue in metallurgy, mine, coal, petrochemical industry, building materials, environmental protection department etc.

Principle :

This thickener consists of round thickener and harrow scrapping 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.

Features :
  • Deaeration cell is provided to prevent solid particles from attaching to bubbles so that solid particles can fall like a parachute.
  • The mineral-feeding pipe is lower than the pulp surface, it prevents the air to be brought in while feeding.
  • Inner overflow weir is equipped to make the pulp flow on pre-designed route, avoiding short circuit, enlarging the sedimental area.
  • The peg linear is changed from oblique lines to curves. So the discharging underflow has higher density, and treatment capacity is enhanced.
