1. The mineral-feeding pipe is added, 2. The rabble blade is changed from oblique lines to curves - details see: https://www.machineto.com/updated-high-efficiency-thickener-10318461

Deaeration cell is provided to avoid solid particles attaching to bubbles and settling as prachute phenomena
1. The mineral-feeding pipe is beneath the liquid level lest air to be brought in while feeding.
2. The feeding casing is moved to a lower position and a receiving plate is equipped. Therefor, the fed slurry fall evenly and steadily, preventing rolling phenomena because of the residual pressure from feeding.
3. Inner overflow weir is equipped to have the pulp flow on pre-designed route, avoiding short circuit ,enlarging the sediment area.
4. The pattern of the overflow weir is made into indented shape, eliminating part suction phenomena induced by unleveled overflow weir.
5. The rabble blade is changed from oblique lines to curves.So the discharging underflow has higher density, and treatment capacity is enhanced.
