Abstract
The article is devoted to research work, in which an attempt is made to apply the Blaine apparatus for direct assessment of filterability of different materials. In the theoretical part of the article the main laws linking the Blaine index of the powder material and the average specific cake resistance are described. A number of experiments with materials taken from actual operating plants are carried out. To determine the Blaine-index the laboratory Blaine apparatus is used and standard tests of filterability on the batch pressure filter is used to determine the average specific cake resistance. As a result of processing experimental data and the necessary calculations direct relations between the Blaine-index and average specific cake resistance are obtained.
