An Elutriator is vertical tube through which a fluid passes upwardly at a specific velocity while a solid mixture, whose separation is desired, is fed into the top of the column. The large particles, which settle at a velocity higher than that of the rising fluid, are collected at the bottom of the column, and the smaller particles are carried out of the top of the column with the fluid. Several columns of different diameters in series may be used to bring about a further separation. The set up consists of two vertical tubes of different diameter in which water is passed at a controlled velocity. A tank with pump is provided for re-cycled water supply and flow rate is measured by Rotameter and controlled with the help of control valve. The tubes are arranged in a fashion of ascending cross-section area. The particles are introduced through a feed hopper provided at first tube, the smaller particles are carried over in the fluid stream, while the large particles settle against the upward stream. The overflow from the first tube introduced at the bottom of second tube is passed vertically upwards and the overflow from the second tube introduced at the, is passed to drain. The weighed sample originally placed in the first tube of smallest diameter is classified into fractions according to their settling velocities. The fractions are collected in successive tubes by a special arrangement and may be dried and weighed to make analysis.

MAGNETIC SEPARATOR MAKE : CREATIVE LAB MODEL NO:CLMO-16
DESCRIPTION:
Materials, that have different magnetic attractability, may be separated by passing them through a magnetic field. Most often, magnetic separation techniques are used to remove iron, steel or magnetic iron oxide from materials low in magnetic attractability. These devices operate in either a continuous or a cyclic manner. Continuous devices usually have a belt which moves over the lifting magnetic poles to carry the magnetize partials into a region of low or zero magnetic field, where they are released. The present set-up is of In-line lifting magnet type. The set-up consists of two belts moving separately in opposite direction at slow speed. Feed through a vibrating hopper is conveyed over first belt and allowed to pass near the second belt, which is under magnetic field. The magnetic field is generated by permanent magnet kept in a box. Magnetically inert material drops off the belt in a normal manner. Magnetic material is held on the belt, however, and finally drops off the belt as it leaves the magnetic field. Both the belts are fitted on the pullies and drived by an electric motor coupled with a reduction gearbox.

FROTH FLOTATION CELL MAKE : CREATIVE LAB MODEL NO:-17
DESCRIPTION:
Mixed liberated particles can be separated from each other by floatation if there is sufficient difference in their wettability. The floatation process operates by preparing a water suspension of a mixture of relatively finely sized solids. This is usually done in an agitated chamber open at the top. Fine bubbles of air are then dispersed through the agitated suspension to form a froth that rises to the top of the chamber. Particles that are radially wetted by water (hydrophilic) tend to remain in the water suspension. Those particles that are not easily wetted (hydrophobic) tend to be collected at the air bubble-water interface and rise to the surface attached to air bubbles. Thus differences in the surface chemical properties of the solids are the basis for separation. The set up consists of a agitated chamber open at the top. In the chamber, an impeller coupled to a shaft is fixed in a stationary diffuser. Low-pressure air is allowed to enter in the stationary diffuser through the air passage provided with the agitator. The collector coated mineral particles adhere to the rising bubbles and are carried to the top of the cell to be removed in the froth product.

·To study the performance of Froth Flotation Cell.
