### IMPACT GRINDING OF DAMP MATERIALS

Pages 88 - 91

According to the authors of the article, it has been proven that dry and damp materials crushed in grinders of the shock type demonstrate different grinding patterns. Therefore, there is a need to explore the influence of the moisture content produced on the efficiency of grinding. The most efficient grinding mode is the one that assures maximal probability of destruction.

Centrifugal grinders were used to analyze the grinding process. The experimental data have proven that the probability of destruction of damp samples is a lot higher than the one of dry samples, given the same initial dimensions of particles and the loading intensity.

The rise in the probability of destruction is stipulated by the fact that that the grinder speed at which crushing is triggered is lower in case of damp samples than in case of dry ones. Expressions for speed that describes destruction initiation and the probability of destruction depending on the type of materials, the moisture content and the loading intensity have been derived.
