ANALYTICAL REGULARITIES OF FILLS OF CO-SIZED AND DIFFERENT-SIZED PARTICLES

Refi ned analytical dependences have been presented for assessing basic parameters of co-sized and different-sized randomly arranged particles and/or granules of fi lls, which make it possible to rigorously assess the properties of the fi lls by the average particle (granule) size, the relation of the average sizes of large and small particles, and the porosity. The presented procedure takes account of the actual properties of powder fi lls and their clustering. It permits determining the porosity, the coeffi cient of internal friction, and the average coordination number of particles or granules in the fi lls. The results obtained from the proposed dependences are in good agreement with experimental data
