The thickener body, or tank, is a thickeners most obvious elem ent and its shape indicates its desig n priorities. For a given flowrate, t hickeners in a clarification duty w ill have large ...
DEEP CONE THICKENERS. deep cone thickeners are designed and constructed to give optimum performance and reliability in even the toughest applications. The deep cone provides a smaller footprint than a rake style thickener saving space on site. The thickened sludge underflow can reach solids content of over 50%.
14/12/2015· The dense Thickener solids are raked to the thickeners underflow cone and are removed via a slurry pump through the underflow pipe. Underflow slurry densities can vary based on the type of material being processed, size distribution of solids being settled, or other process factors but as a general rule, range from 35 50% solids by weight.
power pack as well as an optional lifting device. Electric drives are available for smaller thickener units. The lifting device is used to raise the rakes above the mud bed if the solids are not removed timeously. Single or multiple lifting cylinders can be employed for this purpose. A lifting device promotes a dependable and continuous operation
Deep Cone® Thickener. The Deep Cone Thickener is a critical piece in optimising your sedimentation performance. This products cost effectiveness matches its quality and dependability. Your operation needs quality machinery to remain productive. Thats particularly true when it comes to the thickener you use. Higher underflow pulp ...
Thickener tanks may be constructed either from steel or concrete and may reach diameters of 120 meters and in earthen basins up to 180 meters. Most of the chemical process industries prefer the steel tanks construction since they may be elevated above ground level, allow inspection of the tank's floor for leakages and bring the underflow slurry pumps nearer to the
A circular thickener comprises a relatively shallow, open top cylindrical tank with either a flat bottom or a bottom shaped in the form of an inverted cone . The feed mixture is gently and continuously introduced to the feedwell in which exists a pool of settling suspension along with any additional coagulant or flocculant.
Thickener units are available up to 90m diameter with a range of sidewall and centre pier mounted bridge designs, electric and hydraulic drives and fully integrated lift and automated control systems. Tanks are available in site bolted, site welded and concrete designs.
01/06/2016· Thickener Rakes and Supports Metallurgically, and mechanically, Rakes are correctly designed. From a metallurgical point, the exclusive design of the Spiral Rake imparts a continuous turning motion which conveys the thickened pulp from
16/06/2017· Beginners guide to thickeners. Thickening is a process where a slurry or solid liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water . The driving force for the separation is gravitational, where the differences in phase densities drive the ...
