A thickener/clarifier drive unit supplies the torque to rotate the rake arms through the thick sludge. The drive is usually made of cast iron because of its durability. Usage Examples. Thickeners and clarifiers are often used in water and wastewater treatment plants to remove solids, chemicals, microbes, and other impurities.
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 the thickener. This is called the CONE. It is from this cone that the thickener underflow is taken. During normal operations of the circuit, the thickener may be pulled ...

3. High-Efficiency Thickener. In addition to the inclined plate installed in the thickener, the high-efficiency thickener has a special flocculant adding mechanism. The diameter of the thickener can be reduced to 1 / 3-1 / 2 of that of the common thickener, and the floor area is only 1 / 9-1 / 4 of that of the common thickener.
The overflow of either thickener W or thickener X may be used for dilution in the agitators without affecting the distribution of values in the system. By using the overflow of X a lower grade of solution is obtained, which may be beneficial, and the dilution of feed to thickener W is decreased. TYPE B. Dissolved Value Loss. Conditions assumed:
The measurable parameters that can be used for thickener control include thickener feed flow rate, feed density, underflow density, overflow clarity, bed level, bed mass, rake torque, rake height, solids settling rate and underflow rehology.

Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where ...

Thickening is used during two primary mineral processing operations: water removal and desliming. During water removal, the pulp density is increased through the injection of flocculants. These flocs settle and create a dense pulp while clarified water is removed through the overflow. During desliming, fine particles are removed through the …

reflects continuous thickener operation. That is, one which can predict thickener underflow concentrations as changes in the feed rate or feed density occur, from on line information, or, approximately from batch sedimen tation data. Historically, much effort has been directed to thick ener design from batch sedimentation data (3). This grad
The processing capacity of the thickener decreases. In order not to affect the circulation capacity of the whole concentrator, the thickener has to draw ore when the underflow concentration is not enough, resulting in the loss of water resources and increasing the work capacity of filtrating equipment.
Depending on the type of thickener, the underflow will range in density from a free-flowing mud to a paste. Thickeners are characterized by having higher side walls, steeper floor slopes and a more robust …
