Slurry Densities

Slurry is a mixture of a solid and a liquid. The density of a slurry can be calculated as. ρ m = 100 / [c w / ρ s + [100 - c w] / ρ l] (1). where . ρ m = density of slurry (lb/ft 3, kg/m 3). c w = concentration of solids by weight in the slurry (%). ρ s = density of the solids (lb/ft 3, kg/m 3). ρ l = density of liquid without solids (lb/ft 3, kg/m 3)

    The rake mechanism is used to move the settled solids (also called the slurry) toward the center of the tank where they can be removed. The rake mechanism consists of a series of rakes that are suspended from multiple rotating arms. As the arms rotates, the rakes move through the slurry and push them toward the center of the tank.

    Advances in Thickener Flocculant Delivery

    Mixing of the feed slurry with dilution liquor. In most cases the feed slurry is diluted before or in the feedwell to improve the flocculation. This may seem counter-intuitive given the overall objective is to thicken the slurry; however the improvement in flocculation and hence settling rate is more than enough to compensate.
