The Parameters Affecting The Classification of The Hydro Cyclone

The basic principle of the cyclone is to separate liquid-liquid, liquid-solid, and other two-phase or multi-phase mixtures with a certain density difference under the action of centrifugal force. The mixed liquid enters the cyclone tangentially at a certain pressure, and a high-speed rotating flow field is generated in the cylindrical cavity.

The part of the mixture moves downward along the axial direction at the same time under the action of the swirling flow field and moves downwards along the wall when it reaches the cone section and is discharged from the underflow port, thus forming an outer swirling vortex flow field. The low-density components move toward the central axis and form an upwardly moving internal vortex at the center of the axis, which is then discharged from the overflow port, thus achieving the purpose of separating the two phases.

Parameters affecting the classification of the hydro cyclone

1. Diameter and height of cyclone cylinder

Increasing the diameter of the cyclone can improve the processing capacity, but the overflow granularity becomes coarser, and vice versa. The height of the cylindrical cylinder has an effect on the residence time of the slurry in the cyclone and the classification efficiency, but it is not good if it is too high or too low, generally 0.6-1.0 of the diameter.

2. Diameter of the ore inlet of the cyclone

The diameter of the feed port is usually 0.08-0.25 of the diameter of the cyclone. More than this value can increase the throughput, but the classification efficiency is low. The mine-mouth is often made into a rectangular shape.

3. Diameter of the cyclone overflow pipe

The diameter of the cyclone overflow pipe is generally 0.1-0.4 of the diameter of the cyclone, which can be used to adjust the relative yield of overflow and sedimentation. The diameter of the overflow pipe increases, the overflow flow increases, the overflow particle size becomes coarser, the fine particles in the sedimentation decreases, and the concentration increases.
