If the thickener has been left full of pulp but without operating pumps or rake mechanism, there is a serious danger of sanding, particularly after a number of hours of in operation. If the rakes are in the pulp, raise them slowly out of the pulp to their highest position by the manual lifting device. ... Thickener Normal Operation Procedure.

Thickener operations Thickener operations work to recover clear water and to generate thickened tailings. In the thickener, the solids separate from the water by means of decantation, and they descend to the bottom of the tank. Consequently, the water becomes clearer at the top of the tank, creating separation layers all the way to the bottom.

4.Dewatering operation of recovered minerals in composite iron ore. Flocculant is one of the ways to improve the efficiency of thickeners. The high-efficiency thickener adds flocculants to form large flocs in the pulp entering the thickener, which greatly improves the working efficiency of ordinary thickeners.

Thickeners are designed to operate continuously with slurry/water consistently flowing into the centerwell with thickener underflow pumping balanced to maintain a mud bed in the thickener. Key to thickener operational efficiency is the solids must be able to settle 2-4 times faster than the nominal water up flow rate.

A thickener is an equipment structure used for the continuous gravity settling (sedimentation) of solids in suspensions. Suspension is fed into one or more basins or chambers and, whilst it is passing through, the solids settle out. The thickened solids are removed together with a portion of the liquid as thickened "underflow".
