The resonant vortex TORNADO installation is a gas-dynamic mill in which the technology of cascaded adiabatic resonance impact grinding is implemented, impact velocities of which are close to a breakdown threshold. The installation is designed in a way so that any particle of the input material gets literally torn by the repeated crossing of the differential pressure zones in the intervortex vacuum chamber, which produces ultrahigh gradient (pressure drops) at the interface (up to hundreds of thousands atmospheres). When the material is injected into such area of pressure differential, a rupture of the material’s structure and clusters occurs. Such mechanism can be compared to the mechanism of material’s sample destruction, which is done in order to determine its strength characteristics at tensile test plants. That is, the grinding occurs not due to the friction or any other mechanic force, but by “air” and resonances, which provide a high and efficient performance, great flow rate of raw material as well as inexpensive exploitation (no rubbing parts) with low power consumption.
