Thickener Optimization in your mining process …

Thickening is the separation of suspended particles from a liquid by gravity settling. For effective thickener control, six measurements are critical: bed mass inventory, bed level, underflow density and flow, flocculent dosing and overflow clarity.

Measuring Settling Rates and Calculating …

The required depth of the thickener may be ascertained by computing the capacity of the thickening zone to contain a supply of solids equal to the total capacity of the tank for the number of hours required to thicken the pulp to the density required in the discharge, and to this depth adding an allowance for the lost space due to the pitch of ...

On the other hand, a key component in the thickener operation is the motion of concentrated settled particles on the bottom of the thickener toward the outlet flow which is located in the center. The transmission is done by two or four rakes in the most common thickeners and the high-speed thickeners.

THICKENERS

Thickeners vary widely in size and configuration, but they all comprise: a. a vessel to provide volume and area needed for thickening, with the area being large enough to allow the solids to settle at a velocity faster than the upward velocity of the liquid; b. a system for introducing the feed and directing it into the flow paths that best ...

Solid – Liquid Separation – Thickening

Thickeners are essentially clarifiers producing a clearer over flow. The design considerations are based on the settling rates of the slowest settling particles and conditions for minimum disturbance of the medium (water) through which the solid particles are allowed to settle.
