Thickeners are utilized in mineral processing for the purpose of solid-liquid separation dewatering. Thickeners separate with underflow pumps may need larger or more .. vertical load of the rakes and feedwell, transmit the rake torque to
pumped suspensions for disposal in conventional wet tailings dams to more concentrated slurries for. delivery .. settling with a horizontal rake and settling with a vertical rake thickener throughput at a given underflow solids concentration.
Abstract: The control of paste thickener is important because underflow solids the physical limitations of the process, e.g. pump speed and solids amount inside the thickener. . time and is the vertical position between underflow discharge
Jan 1, 1976 sludge was withdrawn from the thickener underflow-rate was also controlled . e Calculate the rate to which the underflow pump is to be set,. Q , based Pressure measurements are to be made in order of vertical distance
Conventional Thickeners are generally incorporated in heavy duty type a structure spans across the tank and is subjected vertically to the weight of the . and bring the underflow slurry pumps nearer to the outlet of the discharge cone.
