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.

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 new standard, B964, Test Methods for Flow Rate of Metal Powders Using the Carney Funnel, will serve as a complement to standard B213, Test Method for Flow Rate of Metal Powders, when B213 cannot be used due to fine powders not flowing through the small-orifice Hall funnel. The Carney funnel has an orifice twice the diameter of the Hall. The Carney funnel has an orifice (5 mm) twice the diameter of the Hall (2.5 mm). This is a complete kit including stand and accessories needed to comply with the standard.

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). Shipped has a complete unit including : stand : funnel, density cup, calibration powder and certificate When B213 cannot be used due to fine powders not flowing through the small-orifice Hall funnel. The Carney funnel has an orifice twice the diameter of the Hall (which is an optional accessory).

Rent a Dust Monitor instrument for 2 weeks. This item is always on stock (yet, we recommend that you make a reservation). This items corresponds to the rental for the the first 2 weeks. If you wish to keep it longer, simply add additional weeks or months. Any additional week is 866 Euros ; additional month : 2599 Euros. If you want to buy the unit, rentals full value is deducted from the instrument's price. Instruments is shipped with fully equipped PC. Training by Phone and Internet.

Includes : funnel, 710 microns sieve (for any other, please specify on PO), vibration unit, anti-vibration tripod. Allows a measurement of the vibrated flow. This kit is similar to the Slope Angle Kit but does not have the accessories for the standard (normalized) determination of the angle of repose. It allows a repeatable and reproducible flow velocity measurement. Not normalized (there is no standard associated to this industry specific method), this measurement is particularly used in the foodstuff, milk powder and cosmetic industries. It aerates the powder in a repeatable fashion and thus remove the operator effect on the apparent density and flow speed. Gross weight : 9 kg Size of the box : 65 x 35 x 15 cm. Density. Requires 220 V for proper operation. Step up converter may be required (not included). Works on all standard frequencies (50-60 hz). This item is always on stock.
