Working Principle

Backward inclined double blades structure was adopted in the design of rotor. When the rotor is rotating, internal vacuum is created both in the upper and lower blade zone. Ambient air is drawn through an air intake pipe and standpipe by the action of upper blade, the bubbles are then micronized and make the minerals easier to stick on the bubbles. Mineral particles are collected by air bubbles forming aggregates in the contact zone, and Mineralized Bubbles aggregates rise by buoyancy towards the froth zone.The pulp from the upper tank zone is recirculated by upper blade, while the lower blade is designed to recirculate slurry from the bottom of tank to minimize sanding of coarse particles.

Features

1.Large aerating capacity, better surface stability and reduced power consumption;

2.Large design clearance between the rotor and stator, the aerating capacity is stable as the gap becoming larger due to wearing of rotor and stator;

3.Self pulp suction capacity, horizontal placed and no auxiliary equipment is needed;

4. Lower speed of rotor to extend wear life;

5.Upper and lower recirculation in well defined path, sanding of coarse particles is minimized;

6.Beveled tank design, stable operation and proven metallurgical design.
