Vertical Load Monitoring. A key feature of the Outotec 2 nd Generation Paste Thickener is Vertical Load Monitoring via Smart Rake Lift one of the only systems in the world able to detect early formation of rotating beds. Tank mounted bed mass sensors can’t detect these loads. By incorporating Vertical Load sensing with plant process data into the ACT Thickener Optimizer Control system

In high compression (HCT) and paste (PT) applications the bed depth or the mass of solids in the thickener must also be selected to ensure the desired underflow density from the thickener is achieved. By adding flocculants and increasing the depth of the solids bed in thickeners, higher degrees of separation can be achieved.
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 was fed until the tank was full. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were

Description. The High-Rate thickeners became popular in the mid 1980's and are relatively newcomers to the sedimentation line of equipment. As already discussed previously Thickeners are a major component in a plant layout and occupy large spaces which may be saved by introducing high-rate machines. Furthermore, they are normally positioned far away from the center of the plant so to allow
