Price on Request: Get Latest PriceAn 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.

Price on Request: Get Latest PriceMixed 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.

Price on Request: Get Latest PriceIndustrial sedimentation operations may be carried out batch wise and continuously in equipment called thickener. The equipment is a cylindrical tank with openings for a slurry feed and product draw off. The tank is filled with dilute slurry and slurry is permitted to settle. Continuous thickeners are large diameter, shallow depth tanks with slowly revolving rakes for removing the sludge. The slurry is fed at the center of the tank. Around the top edge of the tank is a clear liquid overflow. The rake serves to scrap the sludge towards the center of the bottom for discharge. The motion of the rake also stirs only the sludge layer. This gentle stirring aids in water removal from the sludge. The set-up consists of several basic components: a tank to contain the slurry, feed piping and a feed well to allow the feed stream to enter the tank, a rotating rack mechanism to assist in moving the concentrated solids to the withdrawal points, an underflow solids-withdrawal system and an overflow launder. A feed tank, feed pump, and feed tank agitator is provided. A bin for collecting concentrated material is also provided.
Price on Request: Get Latest PriceThe present set up is designed to conduct the separation test. It consists of a flat table which is inclined at an angle of about 3° to the horizontal. Running approximately parallel to the top edge is a series of slats, or riffles as they are turned, about 6 mm in height. The material to be separated is fed on to one of the top corners and a reciprocating motion consisting of a forward direction and return stroke, causes it to move across the table. The particles also tend to move downwards under the combined action of gravity and of a stream of the water which is introduced along the top edge, but are opposed by the riffles behind which the smaller particles as the cleaner material tend to be held. Thus, the large particles and the less dense material are carried downwards, and the remainder is carried parallel to the riffles.
