Abstract: A cutting mill is disclosed which comprises a housing formed of upper and lower pivotally related housing parts in which a rotor carrying cutting tools is disposed along a horizontal axis. Stator cutting tools are mounted within the housing for coaction with the rotor cutting tools and a sieve is removably mounted in the lower housing part. The rotor is mounted in bearings which are selectively carried by the upper housing part or the lower housing part when such parts are pivoted relative to each other to permit (1) replacement of the sieve when the rotor with its bearings are carried by the upper housing part or (2) accessibility for adjustment of the stator cutting tools in the upper housing part when the rotor and bearings are retained in the lower housing part.
