Industrial tests on the improvement of coarse-grained alumina at the PAR-SUAL Branch are conducted during the period of stable operation of the enterprise. Hydrate hydro classification was included in the apparatus-technological scheme of aluminate solutions processing on special hydro classifiers (HC) of VAMI design. The unbalanced part of fine fractions was eliminated in production.
The issues of optimization of nepheline-limestone charge preparation processes based on the principle of independence of grindability of individual components are considered. Recommendations are given for improving the efficiency of grinding equipment at the PAR-SUAL Branch.
The Russian Federation has accumulated a significant amount of morally and physically obsolete ammunition with powder and propellant charges made of ballistic missile solid propellants. These are valuable energy-rich materials that need to be utilized. A new direction of utilization of charges with expired storage time into extended and superimposed shaped charges as well as technical solutions for effective and safe processing of tubular nitroglycerine and pyrosilicone powders into industrial explosives are proposed. As technologies of utilization of superimposed shaped charges it is proposed to press preheated samples and cutting or drilling under continuous forced heat removal.
