The third type of classification used in mining is the Hydrocyclone, commonly called a Cyclone. Unlike the others it has no moving parts and is worked in conjunction of another piece of equipment, a pump. To understand the Hydrocyclone Working Principle we must first know its components. Beginning at the top, there is the OVERFLOW DISCHARGE.
Operationally, hydrocyclones are good at removing solids with diameters of approximately 35 m and larger. A major drawback of hydrocyclones is that during upsets in flow or pressure drop, the rotary motion in the cone may be interrupted, possibly causing solids to carry over into the overflow liquid.
However, cyclone application in magnetite grinding circuits can cause inefficient operation due to the density difference between magnetite and waste minerals (silica). Magnetite has a specific density of about 5.15, while silica has a specific density of about 2.7. In hydrocyclones, dense minerals separate at a finer cut size than lighter minerals.
Hydrocyclone is a continuously device that utilizes centrifugal force to accelerate the settling rate of particles. GTEK manufacture polyurethane hydrocyclones are designed for separating solids from liquids and have proved to be successful in a board range of mineral processing applications.
A hydrocyclone (often referred to by the shortened form cyclone) is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance. This ratio is high for dense (where separation by density is required) and coarse (where separation by size is required) particles, and low for light and fine particles.
The precision in a hydrocyclones classification ability provides returns as it extracts even the finest of precious minerals which might otherwise be wasted. The natural force generated by the hydrocyclones shape further reduces energy consumption. How do hydrocyclones work? Hydrocyclones are integral products to process minerals effectively.
A hydrocyclone is a static device that applies centrifugal force to a flowing liquid mixture so as to promote the separation of heavy and light components. The classic hydrocyclone is a closed vessel designed to convert incoming liquid velocity into rotary motion.
The mineral processing industry uses hydrocyclones in this way. It also uses them as heavy media separators where the liquid density is increased to be intermediate between a light mineral and a heavy mineral. The light then passes to the overflow, the heavy to the underflow. Applications extended to the chemical and food industries.
Hydrocyclones are preferred units for sizing or desliming large slurry volumes cheaply and because they occupy very little floor space or headroom. They operate most effectively when fed at an even flow rate and pulp density and are used indi vidually or in clusters to
