  • Continuous Thickening Theory

    In a continuous thickener the downward solids velocity with respect to the thickener wall is the sum of the settling velocity of the solids by gravity alone, Vi, plus the downward velocity caused by removal of the thickener underflow, U. The rate at which solids move downward by gravity alone is expressed as the product of the concentration of the solids in a layer, Ci, and the settling

    Likewise, thickeners are often used for storage to facilitate the continuous feeding of downstream filters or centrifuges. Historically thickeners were introduced to the mining industry in 1905 when the beneficiation of ores by froth flotation was invented in Australia.

  • How a Thickener Works Mineral Processing & Metallurgy

    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

  • 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.

  • Thickeners Mineral Processing & Metallurgy

    Thickeners, equipped with the patented spiral scrapers and angle rakes are a distinct improvement over all types of mechanical raking devices now in use.

  • Thickeners Solid Liquid Separation

    Rake driven thickeners for continuous operation can impose a substantial burden on capital investment. Unlike many other types of equipment, thickeners have no stand-bys so if one goes out of commission it cannot be by-passed. Consequently, if this happens other thickeners have to take the extra load but if the plant incorporates just one

  • THICKENERS Thermopedia

    A thickener is an equipment structure used for the continuous gravity settling (sedimentation) of solids in suspensions. Suspension is fed into one or more basins or chambers and, whilst it is passing through, the solids settle out. The thickened solids are removed together with a portion of the liquid as thickened "underflow".

  • Measuring Settling Rates and Calculating Thickener Capacity

    In a continuous thickener, the four zones previously described in discussing intermittent settling are generally present as shown in Fig. 2. At the top there is a zone of clear water, A. Beneath this is zone B, consisting of flocculated pulp of uniform consistency.

    There are three main types of thickeners/clarifiers: bridge support, column support, and traction. In a bridge support thickener, such as the one shown below, the rakes and drive mechanism are suspended from a bridge that spans the diameter of the tank. They are usually only economical for diameters of fewer than 100 feet.
