Abstract: This is a method for working and processing different materials, mainly elastomers, in different manufacturing processes. Moving cutting tools act upon the material to create ultrasonic-frequency oscillations of the material in a working zone. The power of the drive units is set at no less than 100–300 kW. The revolution speed of the tool is set in the range of 3,000–12,000 rev/min. The quantity of cutting edges for the tool is selected according to the relation ?×n is less than 800, where ? is equal to the angular velocity of the tool and n is equal to the number of cutting edges of tool. The attach angles of the tool are set in the range of 85–95 degrees. Separate particles of material embedded to the cutting portion of the tool are removed using a fluid flow containing gas and/or liquid. The effect is an enhanced efficiency of method, increased disposition degree and uniformity of ready product structures.

Abstract: A system for working and processing material, for example, for disintegrating different material, especially elastomers, in different branches of industry for lowering quantity of waste. The apparatus includes a housing with: branch pipes for introducing initial material and discharging a ready product. The working tool is mounted on a shaft inside the housing. The tool is connected with a drive unit. The surface of the tool is formed by large number of cutting edges with ducts embedded into the body of the tool. Cavities of ducts are joined by means of shaped passages with a source of pressurized fluid. An angle of attack of the cutting edges is selected in the range of 85–95 degrees. The drive unit power is in the range of 100–300 kW; the revolution number of the tool is in the range of 3,000–12,000 rev/mm. The effect is an enhanced efficiency of the apparatus, increased dispersion degree and uniformity of structure of the product.
