Principle of As-300 Hall Flowmeter

Principle of As-300 Hall Flowmeter

Hall Flow Rate of 50 g metal powders AS-300 Hall Flowmeter Funnel determines flow rate by measuring the time taken by 50 gram of a metal powder to flow through a calibrated hall flowmeter funnel/orifice of standardized dimensions(0.1 inch/2.5 mm) according to International Standards.



Apparent Density of free-flowing powders AS-300 Hall Flowmeter determines the apparent density by permitting a volume or certain quantity of powder in a loose condition to flow from a hall flowmeter funnel orifice Diameter 0.1 inch/2.5 mm into a specified density cup of definite volume(25 cm³) under controlled conditions.  The mass of powder per unit volume (the ratio between the mass and the volume) is recorded and reported as apparent density.



Apparent Density of non-free-flowing powders AS-300 Hall Flowmeter determines the apparent density by permitting a volume or certain quantity of powder in a loose condition to flow from a Carney funnel diameter 0.2 inch/5.0 mm into …

Electrolysis process And reduction process information

                                                      Electrolysis 

                In this method, an electrolytic cell is set up as shown in figure.  The desired metal is made to act as anode. Anode slowly dissolves and gets deposited on the cathode from where the deposit is removed, washed and dried.

                                                           Reduction 

                            Reduction process is carried out in an atmosphere controlled furnace.In reduction process, the compounds of metals usually oxides like iron oxides are reduced with CO/H at temperature below melting point of metal. Tungsten, molybdenum, iron, cobalt, nickel powders are commercially produced by this process.
