The paper considers vibratory disintegration technologies application in processing of different materials. The technologies in question are based on vibratory disintegration method, essentially being constrained autogenous material grinding inside its own layer under action of vibro-impulse compression with simultaneous shift. Level of force action upon material layer is regulated within its structure flawed surfaces ultimate stress limit range. This approach to material breaking makes vibratory disintegration a universally applicable method for processing raw materials with different mechanical-andphysical properties. Process performance parameters of vibratory crushers of different types are presented with reference to fine metal powders production, recycling and regeneration of abrasive and refractory materials. It is shown, that finished product required range of particle dimensions and shape are provided through vibratory crushers’ parameters regulation. Processing of mineral and man-induced raw materials at a number of operations permitted to produce powders utilized in manufacturing of items with high specifications and performance. It is shown, that if compared with conventional technologies in the areas of application in question, vibratory disintegration provides for higher technical-and-economic performance indices.
The study was performed at the REC «Mekhanobr-Tekhnika» with the aid of the Russian Science Foundation Grant (Project No. 17-79-30056).
