Crushing properties of silicon and titanium carbides in a vertical vibratory mill

The vibratory mill type as well as the correlation between the grinding bodies' weight and size and the materials being ground have been examined to determine their influence on the particle size and the grinding factor when silicon and titanium carbides were ground in a vertical vibratory mill. It has been shown that the grinding efficiency increases when smaller grinding spheres are used, and that a single sphere impact energy and the probability of particles' segregation reduce the grinding time.Dnepropetrovsk Mining Institute.

Using a vertical vibration mill for refining and mixing components of a carbide steel

The Ukrainian Scientific Research Institute of Special Steels (Zaporozh'e) has developed a technology of production of carbide steel—a composite material for cutting tools. When using this material, the durability of tools increases 2–5 times, in comparison with steels R18, R6M5F3, R6M5K5, and R9K5. Industrial tests of punches in cutters for mining combines, hydraulic monitor attachments, drilling bits, and deforming dies of carbide steel have shown that their durability is close to the durability of hard alloys while their production costs are lower.
