CLINCH RIVER Manufactures and Distributes
R&S CERAMIC CYCLONES

Ceramic cyclones meet the demanding requirements of today's coal and mineral processing industries. R&S Ceramic Cyclone models available from Clinch River Corporation include:

Model RS/C Classifying

Model RS/HM Heavy Medium

Model RS/WO Water Only

Combinations and alternate versions are possible due to the interchangeability of the inlet, vortex, and apex orifices. This interchangeability permits fine tuning in difficult or changing feed material applications.

Precision cast monolithic ceramic liners reduce joints providing extended life and longer warranties in conditions where abrasive products or corrosion might cause excessive wear on metal or tiled components.

MODEL RS/C - Classifying Cyclone

Model RS/C Classifying Cyclones maintain a consistent efficiency and accuracy in separation, concentration and classification or dewatering over a wide range of materials. Differences in specific gravity and particle size can be compensated for and fine-tuned to optimum performance by selecting components with various orifice sizes. Inlet, underflow and vortex finder diameters can be varied in an infinite number of combinations to accomplish the separations or sizing at the capacity desired. Further control may be exercised by adjusting the inlet feed pressure.

Model RS/C is a modular design that permits adding or subtracting cones to increase or decrease size for meeting changing requirements in processing. Components subject to more wear through abrasive or corrosive action can be replaced without disturbing the other sections. Each cone section has its own ceramic liner for economy of replacement.

In small-particle, high-velocity impingement environments, cast refrax silicon nitride bonded silicon carbide combines the abrasion resistance of silicon carbide with the extremely strong silicon nitride bond and has outstanding corrosion resistant properties. Standard ceramic liners offered are cast refrax silicon carbide. Optional alumina ceramic tile is available.

The piped outlet version is standard on this cyclone. However, a NiHard overflow cap with long wear life and reduced maintenance is also available. The cap also allows a more compact installation that the piped elbow and may be had in NiHard or ceramic tile lined.

Cyclones may be ordered in clusters of 4, 6, or more, complete with distributor and collection tubs, ready to set into your circuits.

MODEL RS/HM - Heavy Medium Cyclone

Model RS/HM Heavy Medium Cyclones permit upgrading marginal coal seams to premium quality by removing ash forming minerals, gangue, and pyritic sulfur. They separate and clean a full range of coal and mineral products down to zero efficiently, through all capacities. Using a viscose mixture of water, product and magnetite, specific gravities are carefully controlled to achieve desired separation of impurities regardless of particle size or shape.

This cyclone is superior in recovery of coal fines that are lost in other processes, increasing the output and profitability of the preparations plant. Heavy Medium Cyclones produce no measurable degradation of coal or mineral products.

Magnetite losses can be minimized through a patented magnetic medium recovery system and closed circuit water recycling.

Components of the cyclones can be replaced individually, a feature especially desirable in sections subject to unusual abrasive wear.

Cast refrax silicon nitride bonded silicon carbide ceramic liners are offered as standard, with an optional alumina ceramic available.

The piped outlet version is standard on this cyclone, however, a NiHard overflow cap, with long wear life, reduced maintenance, and shorter overall length, is also available.

MODEL RS/WO Water Only Cyclone Model

Model RS/WO Water Only cyclone is offered in standard or high capacity units, achieving separation through extremely high centrifugal forces in the ascending vortex. Used as scalpers ahead of other cleaning units such as heavy medium cyclones or concentrating tables, they can reduce the size of or number of these units. This lowers the cost of preparation and recovery significantly. Installed following Jigs in middlings circuits, Water Only cyclones offer an inexpensive alternate to reclaiming fine material liberated by crushing that may otherwise be misplaced.

Like the other cyclones in the line, the Water Only cyclone is of modular design and construction. Components subject to heavy wear can simply be replaced without disturbing the other sections.

In small particle, high velocity impingement environments, cast refrax silicon nitride bonded silicon carbide combines the abrasion-resistance of silicon carbide with the extremely strong nitride bond and has outstanding corrosive-resistant properties. The standard ceramic liner is cast refrax silicon carbide. Optional alumina ceramic AD-90 is available.

The piped outlet version is standard on the cyclone. However, a NiHard overflow cap with long wear life, reduced maintenance, and a shorter overall length is also available.
