1.Deaeration cell is provided to prevent solid particles from attaching to bubbles so that solid particles can 

fall like a parachute. 

2.The mineral-feeding pipe is lower than the pulp surface; it prevents the air to be brought in while feeding 

3.The feeding sleeve is moved to a lower position and receiving plate is equipped. Therefore, the fed slurry 

fall evenly and steadily, preventing rolling  phenomena because of the residual pressure from feeding 

4.Inner overflow weir is equipped to make the pulp flow on pre-designed route, avoiding short circuit, enlarging 

the sedimental area 

5.Inner overflow weir is made into indented shape, eliminating part suction phenomena induced by unleveled overflow weir.

6.The peg linear is changed from oblique lines to curves. So the discharging underflow has higher density, and treatment capacity is enhanced.
