grinding equipment. SUBSTANCE: mill has charging units and nozzles built in charging units. Nozzles are adapted for supplying energy-carriers and connected to energy-carrier generators. Nozzles are placed in speeding up pipes axially aligned with milling chamber having dust drawing branch pipe adapted for carrying out material to be ground for separation. Energy-carrier generators are made in the form of gas-detonating chambers having casing with channel made in the form of Archimedes' spiral, and mixer. End of this channel is connected to nozzle. Mixer is fixed in casing so that gas mixture is supplied to head end of channel. Cover is rigidly secured to casing. Sparkplug is built in cover in opposed relation to mixer. Mill of such construction is used for fine and superfine milling of, for instance, pigments. Milling is provided by supplying material in countercurrency to gas flows. EFFECT: increased milling efficiency and simplified construction. 2 dwg
