Hydrocyclone is useful for desliming, dewatering, and separating aggregates from the mineral. Hydrocyclone is cone-cylindrical in shape with a tangential inlet feed and cylindrical outlet axis. In the mining industry, the hydrocyclone separates the coarse and fine particles from the slurry. The Hydrocyclone is a high-throughput gravity separation device, in this, the separation happens based on particle weight. The working principle of hydrocyclones starts from tangential inlet and separate particles with the help of the separation principle. Components of Hydrocyclone To have a better understanding of Hydrocyclone it is important to understand the components.
Working Principle of Hydrocyclone The operating principle of Hydrocyclone uses a vortex-conical effect. Liquid enters at the top of the inlet which helps in creating tangential flow and creates a strong vortex inside the machine. The slurry spins at high velocity, which results in separating the liquid into two different particle sizes. The finer particle goes out through the central pipe outlet, while the coarse particle falls out of the outlet axis. Each cyclone is specifically designed for a specific threshold, this includes the size of the particle and weight of the slurry in the Hydrocyclones. Factors That Impact Efficiency Of Hydrocyclone The volume of slurry is added through the inlets. You must remember, that the volume must not exceed the capacity of the outlet that allows the waste material to escape. The size of the vortex finder is crucial. The factors which became operating variable while dealing with cyclone is Apex size, Vortex Finder size, and the volume of the feed. If any of the variables is unbalanced, i.e, either pressure is too high, or the cyclone is overloaded. In this, if the vortex is generated and an air column is formed at the center of the vortex, it may not sustain. The air collapses, decreasing the velocity of the spiral losing the centrifugal force, leading to the collapse of the system and releasing the same slurry which entered through the inlet. The variables must be balanced to create constant pressure, which ensures positive control over ore classification. Conclusion
Hydrocyclones is an integral part of the mineral beneficiation process in the mining industry. The leading hydro cyclone manufacturer in India is Tega industries and Metso India.
