Flowability

The Flodex apparatus consists of a receptable cylinder with interchangeable discs with holes of various diameters at the bottom. The determination of flowability is based upon the ability of the powder to fall freely through a hole in the disc. The smaller the hole through which the powder falls freely, the better is the flowability. Fifty grams of material is loaded carefully into the cylindrical container to fill it to within approximately 1 cm of the top. Tap the funnel lightly so that the powder is introduced without packing. After loading, wait about 30 secondsthen move the release lever and watch if the powder flows. Start with a 16 mm flow disc for powders not previously tested. If the test is positive, repeat the procedure with smaller discs until the test is negative. If the powder does not flow, repeat the test with discs with larger holes until thetest is positive. The Flowdex flowability is defined as 1000 divided by the diameter in millimeters of the smallest hole through which the sample will pass three consecutive tests. The Flodex is ideal for determining the intrinsic flowability of powders and highly recommended for the quality control of powders.

Includes : reservoir, plate, funnel, 315 microns sieve (or any other, please specify on PO), vibration unit, anti-vibration tripod. Enables measurement of angle of repose and bulk density while eliminating operator's influence, that is quite common for this type of measurement. The smaller the angle of repose of a dry material, the easier its flow. The opposite is also true for stepper slopes. Angle of repose is a direct indication of flowability. Its determination is simple and the result is a combinaison of the properties that affect flow such as : shape, size, porosity, cohesion, fluidity, surface et apparent density. It is a valuable complement to Flodex index and tapped density. Gross weight : 10 kg dimension : 65 x 35 x 15 cm. This item is always on stock.

Test powder is placed in the sample drum that has two glass sides. A motor rotates the drum. A digital camera with backlight illumination takes images of the powder during the rotation process at the specified speed. In every image collected, the software measures many aspects of the powder, including the potential energy, angle, surface fractal and volume. The Revolution Powder Analyzer calculates the avalanche power by measuring the change in potential energy before and after each avalanche. A free flowing powder will avalanche almost continuously, never building a significant peak. A powder that flows less freely will exhibit avalanches with higher power values.

The Hall flowability method is the measurement of time necessary for a free-flowing powder to pass though a standardized funnel. Geometry, internal surface finish, opening are defined in standards B 213, ISO 4490, ASTM B 212 an ISO 3923/1. This traditional technique should be used only with free-flowing metal powder (or similar).
