The powder flowability tester, vibrating density meter SCI-1 molecular sieve loose packing vibrating density meter adopts a vibrating feeding method to reduce the powder flow resistance caused by the cohesive characteristics of gravity and friction between powder and particles, and promote the natural and uniform filling of powder and particles; More accurate representation of the actual physical characteristics of the product; SCI-1 is an upgraded model of SCI-2, which adds a microcomputer control system that can automatically calculate the values of loose density, bulk density, and tap density, and is equipped with a printer to automatically print the test results, reducing calculation and recording errors caused by human factors and preserving the original test data. This instrument is designed according to the requirements of GB/T6286-1986 Molecular Sieve Bulk Density Determination Method, and is suitable for measuring the loose density, bulk density, and tap density of granular molecular sieves. It is also applicable to measuring other powders and particles with similar characteristics and is compatible with international testing methods.
