The consistency factors' and compression ratios' comparative analysis for the F240 micro-grids of different producers

Abstract

The abrasive grit's and micro-grit's properties were defned for the electrically produced differently sized corundum manufactured by different producers. The static methods were used to defne the particle size distribution and the rheological properties, such as: the bulk density, the tapped bulk density, the flow time from the receiving cone, the angle of natural slip, the yield and compression criteria, the tap density degree (these were the powder's mobility and compressibility), as well as some dynamic characteristics were explored with the using of the Revolution device. The scanning electronic microscopy was used to study the powder's morphology. Based on the investigating results we carried out the comparative analysis and drew the conclusions. Ill.2. Ref. 9.
