Mechanical Operation Lab

An Elutriator System 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 rota meter 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.

Mixed liberated particles can be separated from each other by Froth Flotation Cell Apparatus if there is sufficient difference in their wet ability. 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 radically 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.

A Ribbon Mixer Apparatus consists of a horizontal trough containing a central shaft and a helical ribbon agitator. Two counteracting ribbons are mounted on the same shaft, one moving the solid slowly in one direction, the other moving it quickly in other. The ribbons may be continuous or interrupted. Mixing results from the turbulence induced by the counteracting agitators, not from mere motion of solids through the trough. Some ribbon blender operates batch wise with the solids charged and mixed until satisfactory; others mix continuously, with solids fed in one end of the trough and discharged from the other. Ribbon blenders are effective mixers for thin pastes or for powders that do not flow radically. The whole assembly is fitted on rigid ms structure. The trough is unloaded through an opening in the bottom. The setup studies in principles of mixing and can be operated as batch wise or continuously.

Materials, that have different magnetic at tractability, may be Magnetic Separator by passing them through a magnetic field. Most often, Magnetic Separator techniques are used to remove iron, steel or magnetic iron oxide from materials low in magnetic at tractability. 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 derived by an electric motor coupled with a reduction gearbox.

The most common types of pressure filters are filter press. A filter press contains a set of plates designed to provide a series of chambers or compartments in which solids may collect. The plates are covered with a filter medium such as canvas cloth. Slurry is admitted to each compartment under pressure; passes through the canvas cloth and out a discharge pipe, leaving a wet cake of solids behind. Plates and frames sit horizontally in a metal rack, with cloth covering the face of each plate, and are squeezed tightly together by a screw. Slurry enters at one end of the assembly of plates and frame. It passes through a channel running lengthwise through one corner of assembly. The set up consists of 7 plates and 6 frames. Frames are covered with filter cloth.

The Sigma Mixer Apparatus consists of two counter-rotating blades in a rectangular trough curved at bottom to form two longitudinal half cylinders and a saddle section. The blades are driven by gearing at either or both ends. The mixing action is a combination of bulk movement, smearing, stretching, folding, dividing and recombining as the material is pulled and squeezed against blades, saddle and sidewalls. The blades are pitched to achieve end-to-end circulation. Rotation is usually such that material is drawn down over the saddle. The blades are tangential and run at different speeds, with the advantages of faster mixing from constant change of relative position. The blade design most widely used is the sigma blade. The sigma blade mixer is capable of starting and operating with either liquids or solids or a combination of both. The sigma blade has good mixing action, readily discharges materials that do not stick to the blades and is relatively easy to clean when sticky material are being processed. The drive is given through an electric motor coupled to a reduction gearbox. The whole assembly is fitted on rigid ms structure. The tilting mechanism is provided for discharge of product.

Gyratory Sieve Shaker is driven by fhp motor through a reduction gear suitable to carry upto 7 sieves of 15 cm or 20 cm diameter. When clamped the sieve table does not rotate but it is inclined from the vertical axis and the direction of inclination changes progressively in the clockwise direction. In addition to the gyratory motion of the shaker, there is an upward and downward movement ensuring that each square inch of the sieve is utilised. The whole mechanism runs in an oil bath.

The Rotary Sieve Shaker reproduces the circular and tapping motion given to test sieves in hand sieving. The uniform, mechanical action ensures accurate and dependable test. Using the regular height 20-cm diameter sieves, one sample can be tested on a series of six sieves of different openings, all with one operation of machine. The rotary sieve shaker is simple and durably constructed and is run by a fhp motor. The running parts operate in oil. The machine is easily installed. No special foundation is required. Test sieves are supplied at extra cost.
