HAMMER MILL MAKE : CREATIVE LAB MODEL NO:CLMO-06
DESCRIPTION :

Hammer mill consists of Pivoted hammers, mounted on a horizontal shaft. Crushing takes place by impact between the hammers and anvil plate. The hammers delivers heavy blows to the feed material while it is in suspension, driving it against an anvil plate until it is fine enough to pass through the opening of the mesh fitted in the bottom of the Mill.The present Hammer Mill has sturdy housing that contains 4 Nos. of T shaped hammers, pivoted to a disc, which is fitted with the shaft of the mill turning about the horizontal axis. The shaft is directly coupled to a motor. The housing contains a semi-circular teethed liner (or anvil plate) on the top of it. A glass window to see through in the Mill is fixed on the front cover, which can be opened to change the sieve. Different mesh sizes are provided to get different product size. A hopper with feed opening and adjustment is provided in the Mill. The crushed material is collected in a receiver provided in the set-up. This mill can accept a feed size of 6.5mm or less.

GYRATORY SIEVE SHAKER MAKE : CREATIVE LAB MODEL NO:CLMO-11
 DESCRIPTION:

Gyratory type shaker is driven by FHP motor through a reduction gear suitable to carry up to 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 utilized. The whole mechanism runs in an oil bath. Complete with adopter for 20-cm diameter sieves. Suitable for use from 220/230 volts 50 Hz. AC supply. Test Sieves will be supplied at an extra cost. A time switch from 0 to 60 minutes is provided.


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.

EXPERIMENTATION:
·       To study the performance of Froth Flotation Cell.
·       To find % recovery of mineral in froth from a standard mixture.
UTILITY REQUIRED    
·       Material for Feed, Frothing agents and collectors.
·       Water Supply and Drain.
·       Compressed Air Supply 1 CMH at 2 kg/cm2.
·       Electric Supply: Single phase, 220 V AC, 0.5 kW.
·       Floor Area 1.5 m x 1 m.
