NZSG型高效化改造濃密機 Updated  high-efficiency thickener

NZSG型濃密機增設脫氣槽，以消除固體顆粒附著在氣泡上，似“降落傘”進行沉降，給礦管位于液面以下，以防給礦時氣體帶入。

給礦套筒下移，并設有受料盤，使給入的礦漿均勻、平衡地下落，有效地防止給礦余壓造成的翻花現(xiàn)象。

增設內溢流堰，使物料按規(guī)定行程流動，防止“短路”現(xiàn)象，大幅度增加了沉降區(qū)，溢流堰改為鋸齒狀，改善因溢流堰不水平而造成的局部抽吸現(xiàn)象。

將耙齒線性由斜線型改為曲線型，使之排礦底流濃度增高，從而增加處理能力。

Deaeration cell is provided to  avoid solid particles attaching to bubbles and settling as prachute phenomena The  mineral-feeding pipe is beneath the liquid level lest air to be brought in  while feeding.

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.

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

The pattern of the overflower  weir is made into indented shape, eliminating part suction phenomena induced by  unleveled overflow weir.

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