<p>One or more rotors of an impact comminutor are mounted within a housing. A hydraulic cylinder and piston unit is laterally offset from the axis of the rotor, or the axes of adjacent rotors, being pivotably mounted on a wall of the housing. The free end of the unit can be releasably engaged with a respective rotor or a plate mounted fixedly on the shaft of the rotor and provided with circumferentially spaced apertures for connecting purposes. Thus, operation of the cylinder and piston unit serves to displace the rotor angularly to a desired angular position.</p> |
