FIELD: technological processes.
SUBSTANCE: invention relates to drying and grinding of materials (clay, chalk, dolomite crushing wastes, gypsum, slag, talc, etc.) and can be used in construction, machine building, agricultural and other industries. Invention includes direct-flow drum with discharge chamber and system for holding of dried material in area of torch burning, burner device connected to the drum via air suction chamber with annular slot and charging tube, burner, which exceeds the rated power of not more than 1.5 times, smoke exhauster, also exceeding calculated characteristics of not more than 1.5 times, control cabinet with software. Burner for burning device operates in cyclic mode, wherein power and time of cycle are selected depending on properties of material prepared to grinding.
EFFECT: considerable reduction of costs for drying and grinding of materials, higher efficiency and quality of produced as a result of processing of materials.
