Using the fundamental kinetic laws of materials grinding processes, a resource-energy-saving technology for complex processing and mechanoactivation of mineral components has been developed. For the technology, patent-protected energy-efficient grinding units for selective grinding of materials have been developed: press-roll grinders (PRG) for volume-shear deformation (VSD) of materials and obtaining their microdefect structure; drum ball mills (DBMs) with internal energy-exchanging devices (IEDs), which implement impact-crushing-abrading action with less 10–20 % grinding load. A technological complex was developed for mechanoactivation of fine-grained materials and obtain nanostructured composite mixtures from them: “PRG–VSD”– vibration-centrifugal unit (VCU) of selective grinding at each stage – vortex-acoustic dispersants (VADs) for obtaining ultrafine particles < 5 μm with mechanical-aerodynamic and acoustic grinding. Resource-energy-saving technology has been tested for complex thermomechanical processing of quartzite-iron-containing was teat the Lebedinsky mining and processing plant for production of pigments-fillers for the purpose of volumetric dyeing of products.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
