ABSTRACT:
A cavitator comprising a cavitator plate mounted within a container is vibrated by an oscillator comprising a mechanically rotatable eccentric body to provide low frequency high power vibration. A mechanical linkage between the oscillator and the cavitator plate is tuned so that the frequency of oscillation matches the natural frequency of vibration of the linkage. The tuning can be achieved by modifying the length of the linkage or by choosing the necessary properties of the linkage or by varying the frequency of vibration of the oscillator. Various possible linkages include a pipe formed in sections, an elongated beam supported at its nodes, an annular pipe, and a pipe arrangement with overlapping section. The arrangement is of particular advantage when used with complex cavitator plates including vanes, paddles or rods or when using a cage grinder incorporating a plurality of balls for acting upon the material.
