HIGH DENSITY THICKENER UNDERFLOW WITHDRAWAL DEVICE. BACKGROUND Technical Field This invention relates to thickener tanks and similar separation tank which produce a thickened underflow for removal from the tank. Specifically, this invention relates to a structural means for removing highly viscous and thickened material from the tank through
2020-7-29The Difference Between a Clarifier and a Thickener is subtle as they will visually look the same. Fundamentally, thickeners and clarifiers are both used to settle solids which results in the separation of liquids and solids. Thickeners are used to concentrate solids, while clarifiers are used to purify liquids. A thickener will give you a high density underflow while a clarifier will not. The
2020-7-29In order to develop rational methods of measurement and laboratory testing, it becomes necessary to study the general phenomena of settling rates. Since it was desired to give the public the benefit of these methods at as early a date as possible, together with the knowledge of the general principles of slime settling necessary for a clear understanding of the laboratory tests, we have
Many pump types struggle to meet the demand for pumping the high viscosity and high density mineral concentrate in thickener underflow transfer. Bredel hose pumps are designed to handle high-solids content fluids, such as concentrated ore paste with a solids content of 40-80

Thickener tank EIMCO KCP Thickener tanks are constructed either from bolted steel welded or concrete. Most of the chemical process industries prefer the steel tanks construction since they may be elevated above ground level, allow inspection of the tanks floor for leakages and bring the underflow slurry pumps nearer to the outlet of the
2020-6-11In thickening practice, capacity is usually expressed in terms of thickener cross-sectional area per unit weight of solids per day. Properly, the unit area is shown as a function of underflow solids concentration, and a logarithmic plot exhibits a nearly linear operating line which gradually approaches a vertical slope near ultimate density

2020-7-22There are two basic types of high rate thickener units Lamina or tube settlers and solids recirculation units Lamina Thickeners They contain space-cutting baffles that intercept settling paths at many levels. Solids settle out onto the baffles and are removed from suspension after settling only a short distance. Where and to the extent that removals are governed by settling rates, such
