Thickener Torque -Rakes & Drive
· Each rake arm is higher at its far end than it is where it joins the drive shaft. This is designed this way to give the bed a slope towards the centre of the thickener. As the rakes are turned by the drive shaft they cause the concentrate that has settled onto the bottom of the thickener to be pulled into the discharge chamber at the centre of ...

· rake classifier mechanism. The rake classifier (Figure 9.18(a)) uses rakes actuated by an eccentric motion, which causes them to dip into the settled material and to move it up the incline for a short distance.The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated. The settled material is thus slowly moved up the incline to the discharge.

Mining: the evolution of thickening rake mechanisms ...
· The original thickener mechanism consists of a central drive shaft, two long rake arms, and two short rake arms, both with strut supports and tie rods "tying" the four arms together. The rake arms have scraper blades to move the material inwards, struts to give the arm vertical support, and tie rods to distribute the torque load evenly ...
Arrangements are known for lifting the rake arm structure in the case of thickeners in which solids fed to the thickener are settling at a faster rate than they are being withdrawn with the underflow or when the settled solids tend to solidify. ... The column 1 supports a cage 3 which is rotatably mounted on the column and is driven by a ...

· High rate thickeners are designed specifically to maximise the flocculation efficiency of flocculants. They differ from conventional thickeners in feed well design, size and control. Unlike conventional thickeners, high rate thickeners must use flocculants. The basic design of a high rate thickener is below. Inquire Now
Thickener Operating pH and Lime for Flocculation ...
· If, for some reason, the thickener''s settling rate is too slow, as in the case of the grind being so fine or you are dealing with clay rich ore and now the concentrate stays in suspension. The thickener could be "sliming" and will produce a dirty overflow combined with a low density underflow.
At the end of 2 days at normal feed rates to the thickener, the rake assembly had risen vertically to the limit of its travel. The air check valve 70 was then adjusted to 120 psig. Valve 24 was opened and valve 26 closed. The thickener then discharged 48 hours of normal feed in 8 hours at a very high density.
The control parameters used to maintain stable operation in high-rate thickeners are underflow solids density, underflow withdrawal rate, flocculant dosage, solids inventory in the tank, solids feed rate, and mechanical torque limit restriction of the rotating rake arm mechanism. Lower-yield stress muds, as produced in a high-rate thickener ...
