The Hydrocyclone reviews data on the theoretical, design, and performance aspects of the liquid cyclone, hydraulic cyclone, or hydrocyclone. The book aims to be a source of reference to those who are in industries employing the use and application of the hydrocyclone.

Clarence Kreiser and Jim Miller design cyclones, classifiers and other process equipment for Van Tongeren, in Lebanon, Pennsylvania. The company''s roots can be traced to Hermannus Van Tongeren Jr., who invented the cyclone for dust collection nearly 100 years ago. For more information, visit or call .

The cyclone underflow assay during this period averaged 30g/t indicating that there was a high probability of coarse gold that could be recovered through the gravity circuit. The overall plant recovery averaged % which was significantly lower than historical plant gold recoveries of around 86%. This was a direct result of

cyclone plant circuit was achieved by installation of appropriate instrumentation and interlocking to the programmable logic control (PLC). This allowed for the control of the correct medium sump level, cyclone inlet pressure, mediumtoore ratio as well as online monitoring of density

For design purposes this can be taken as equal to the surface area of a cylinder with the same diameter as the cyclone and length equal to the total height of the cyclone (barrel plus cone). Radius ratio rt/re Fig. 2. Cyclone pressure drop factor Fig. 3. Standard Cyclone dimension as per stairmand (a) high efficiency (b) high gas rate cyclone

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 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.

A cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation. When removing particulate matter from liquid, a hydrocyclone is used; while from gas, a gas cyclone is used. Rotational effects and gravity are used to separate mixtures of solids and fluids. The method can also be used to separate fine droplets ...
