AS-500 Angle of repose tester Hall flow meter Apparent density tester Bulk density tester
Overview
In various powder applications, the shape, size, size distribution as well as cohesiveness of particles in bulk products directly determine the quality of the finished products. In order to control the quality it is recommended to use precise instrument when doing analysis. AS-500 Powder Integrative Characteristic Tester gives accurate angle of repose/rest, apparent density and hall flow.
-It determine the angle of repose/rest according to ISO 902 Aluminium oxide primarily used for the production of aluminium — Measurement of the angle of repose
The principle consists in measurement of the angle of rest on the basis of the cone of bulk material obtained by passing the product through a funnel from a conventional height on a horizontal and absolutly even plate.
-It determines hall flow rate according to ISO 4490 Metallic powders — Determination of flow rate by means of a calibrated funnel (Hall flowmeter)
ISO 4490 specifies a method for determining the flow rate of metallic powders, including powders for hardmetals, by means of a calibrated funnel (Hall flowmeter).
he method is applicable only to powders which flow freely through the specified test orifice
-It determines the apparent density according to Aluminium oxide primarily used for the production of aluminium — Determination of untamped density
The method based on the determination of the mass of a known volume after a free fall of the product without vibration in a stable container. Expression of the apparent density by division of this mass by the mass of a equivalent volume of water.
