Part 1 of this article covered the most common problems in thickener operations caused by thickener design errors and changes in ore properties.. Part 2 will discuss in detail the problems caused by mechanical and maintenance issues (including issues with thickener instrumentation and control) and what can be done to solve them. Conclusions and recommendations
An automatic control system is necessary to keep the operation of the thickener stable, along with the use of online monitoring of the clear water and pulp phases inside the thickener. These layers can be monitored with systems such as SmartDiver and can
2021. 1. 21. Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp

Many thickener installations operate with water recovery below design limits largely through conservative control and low prioritization of thickener optimization. The operation of the thickener must accommodate fluctuations control for disturbances in the process feed stream to deliver a clear overflow and thickened underflow.
2010. 7. 14. A thickener has several basic components: a tank to contain the slurry, feed piping and a feed well to allow the feed stream to enter the tank, a rotating rake mechanism to assist in moving the concentrated solids to the withdrawal points, an underflow solids withdrawal
This sweeping shears the pulp particles, releasing trapped water, which rises to the surface through the sheared material, allowing the solids to settle into a more dense bed of thickened pulp....
Thickener control strategies and shortcomings in current thickener operations are discussed, resin in pulp (RIP), it is difficult to see a viable alternative to th e thickener in most of its
Maximising pulp concentration and keeping underflow slurry uniform is a key focus if you want to enhance productivity and keep efficiency high. The Deep Cone Thickener uses cutting edge technology to ensure your operation runs at peak performance.
