ROLL CRUSHER APPARATUS

The roll crusher has widely application in the industries of mining, building materials, chemical industry, metallurgy, coal and coke industries etc. The roll crusher can crush materials with middle hardness or less than middle hardness into secondary or fine granularity, such as crushing geological ores, mineral, rocks, coke, coal, slag, scoria, and fire-proof material etc. Rock Roll Crusher Working Principle: The fixed part of roller and movable roller are driven by the motor via reducer and v-belt, the raw materials fall into the part between the two rollers from inlet of the machine. The two rollers rotates inward simultaneously. The materials are extruded, crushed and ground, then the end products come out from the bottom of this crusher.

HAMMER MILL APPARATUS

Hammer mill is an economical unit designed for general all-round work for time saving operation. Most often, the only changes necessary are of Screens, hammers and liners.

The swinging hammers, in the rotating hammer rotor, crush materials at the stationery liners before driving them through a screen and type of hammers used. The method of operation is impact grinding. Combination of different hammer styles, liner plates, sieve inserts and wear resistance technology offer almost unlimited possibilities of crushing lumpy, bulky, irregularly shaped, hard & fibrous materials, into coarse to medium fine powder. Machine to work on 220V AC 50 Hz single phase.

PLATE & FRAME FILTER PRESS APPARATUS

Plate and frame filter presses are used in the beverage industry, for example, to clarify intermediate products. A suspension of diatomite and water (recommended) is prepared in a stirred tank. The stirrer ensures that the solid remains suspended and does not settle. A pump delivers the suspension into the individual separating chambers of the plate and frame filter press. A separating chamber is formed by one filter frame and two filter plates. The filter plates are grooved and covered over with filter cloths. The filtrate passes through the filter cloth and flows via the grooves in the plates into a collecting pipe. The filtrate exits the plate and frame filter press through the collecting pipe and is collected in the filtrate tank. The solid material is separated off at the filter cloth, where it forms a growing filter cake. As the filter cake becomes thicker, its flow resistance also increases. When the separating chamber is full, or a maximum pressure difference has been reached, the filtration process is ended. The plates and frames of the plate and frame filter press are pulled apart. The filter cake can be removed. For the next filtration the plates and frames must be pushed back together. A spindle is used to press them together. The press forces ensure that the suspension does not leak from the contact points between the plates and the frames, but is forced through the filter cloth. The flow rate through the plate and frame filter press is adjusted by a valve. The pressure occurring during filtration is indicated on a manometer. The filtrate tank is scaled. This means a stopwatch can be used to measure the flow rate. An included opacimeter allows the solid concentration of the filtrate to be determined. A drying chamber is recommended for evaluation of the experiments. Product Description: Power Source: Electric Voltage: 240 V Frequency: 50 Hz Phase: Single Phase

FROTH FLOATING CELL APPARATUS

Mixed liberated particles can be separated from each other by floatation 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 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.
