A Short History of Deep Cone Thickener Development

In 1973, Robinsky pioneered the use of thickened tailings disposal, which has gained steadily in popularity. Alcan began using the method in 1987, which was fed using deep cone thickeners. Vacuum filters are used at some sites, but many of them use discharge from the last CCD stage. High pressure pumps are typically

Efficient high density thickeners FLSmidth

Thickening is key to a thriving operation. Sometimes you need extra torque for high underflow densities. The High density Thickener packs a punch with plenty of extra torque in a design between a high rate and deep cone thickener. You need reliability and rugged dependability. You need a machine that will stay running longer and get the job done.

Seven Highlights of Xinhai Thickener! Xinhai

It can also use other type thickeners. 02 Highlight 02 moving the feeding pipe below the overflow layer to avoid air mixed in. For traditional ordinary thickener, the pulp to be concentrated is pumped into thickener. The negative pressure in the clarification zone leads to aeration, which is a disadvantage for the full sedimentation of pulp.

Decantation an overview ScienceDirect Topics

As can be interpolated from the table in Figure 18.8, even a single high density or deep cone thickener will benefit the process. Further, if the last thickener in the circuit is of that type, issues related to excess water in the tailings pond are minimized. Similarly, filtered tails would reduce such concerns even more.
