Pumping Thickener Underflow Slurries | Mining | Industries,

Pumping Thickener Underflow Slurries Concentrate Slurry containing a abrasive materials from three areas including very abrasive high grade nickel concentrate, mixture of copper and nickel and copper slurry with low nickel, flows up to 359 l/min (95 US GPM), up to 72% solids density of 4.29 - 4.97.Difference Between Clarifier and Thickener,The 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.

Conventional Thickeners - Solid Liquid Separation

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 outlet of the discharge cone.Thickener underflow slurry - Verder Liquids,Thickener underflow slurry Three applications ranging from the very abrasive to mildly abrasive slurries from concentrator. Concentrate Slurry, Abrasive materials from three areas including very abrasive high grade nickel concentrate, mixture of copper and nickel and copper slurry with low nickel, flows up to 22 m3/h, up to 72% solids solids density of 4.29 - 4.97.Thickener Underflow Level Control,We provide an Emerson Fisher™ Vee-Ball™ V150 Rotary Control Valve designed with hardened materials for thickener underflow applications. This valve provides long-term service life in conjunction with precise control. Precise control is achieved through a direct mounted Emerson Fisher™ FIELDVue™ DVC or a FIELDVue™ in-a-box.
