A pilot-scale grinding technology of ceramic medium stirred mill was proposed in this study. Based on the specific productivity and grinding efficiency, the appropriate grinding parameters were ascertained as follows: material ball ratio of 0.7, ceramic ball medium size ratio (10 mm: 15 mm: 20 mm = 3:2:5), stirring speed of 110 rpm, grinding concentration of 50%, …

The use of vortex layer plants for dry grinding and regrinding of different powder-like materials (quartz sand, cement, micro-marble, chalk, dolomite, and diatomite) is considered. The high degree of efficiency of the plants is experimentally confirmed. Certain technological features of the process of milling of powder-like materials in a vortex-layer plant are established.
