Select slurry concentration: Solid concentration must be known as the specific gravity or density and the rheology of the slurry is dependent on solids concentration which in turn decides the pumping cost. At certain solid concentrations, Slurry will be unstable and very difficult to flow. In such a scenario, proper solids concentration must be known for proper …

differences between the slurry preparation plant and pipeline. The slurry is usually 60–70% water by volume. Once delivered to the agitated storage tanks, a quality control procedure is followed before the slurry is cleared for pumping. The level of quality control depends on the type of slurry and pipeline system. It usually involves routinely
