Comparative Analysis of Mobility and Compactability Indices for F240 Grinding Powders from Different Producers

Аннотация

Properties are determined for electrocorundum grinding grits and powders of different grain size from various producers. Powder particle size distribution and also rheological properties are determined by a static method; bulk and tapping densities, time for emergence from a funnel, natural repose angle, flow criteria, compactability and degree of tapping (indices of powder mobility and compactability), and some dynamic properties using a Revolution instrument. Scanning electron microscopy is used to study features of powder morphology. Results are used for comparative analysis of powders and conclusions are drawn.
