How a Thickener Works - Mineral Processing & Metallurgy

Attempts to make thickening continuous, by using hopper-bottom tanks or cones, were not entirely successful. In these tanks the feed ran in continuously, settled solids were drawn off through a spigot and solution overflowed continuously at the top of the tank.Software for the design and simulation of gravity thickeners,The software permits the simulation of batch sedimentation and the design and simulation of continuous thickeners.

Second Approach Second approach in the design of thickeners is the solids flux approach. Settling velocity, ZSV, is a function of solids concentration. If we plot that, the relationship will look like: Figure 4.

Thickener | Nova Mining

Thickener works in the principle of Gravity sedimentation. This is the most widely applied dewatering technique in mineral processing, and it is a relatively cheap, high capacity process, which involves very low shear forces, thus providing good conditions for flocculation of fine particles.Measuring Settling Rates and Calculating Thickener Capacity,In the operation of continuous thickeners, the feed of the thin pulp at the center of the tank, the overflow of clear liquid at the periphery of the tank, and the discharge of the thickened pulp at the bottom, are generally continuous. In a continuous thickener, the four zones previously described in discussing intermittent settling are,What are thickeners & how do they work - Mineral Processing,Sep 13, 2013 · gravity to the thickener and shall have the energy to aid mixing of flocculant solution with it.
