Abstract
A grinding machine includes first feed screw, first head, first center pin, first knife assembly, bushing and first orifice plate. Second feed screw is coupled to first center pin and rotates within second head. Second feed screw is positioned against the bushing such that the bushing acts as a thrust bearing. Second center pin is coupled to second feed screw and is configured to rotate a second knife assembly. Second orifice plate is arranged on second center pin. Second mounting ring can be linearly adjusted relative to second head to axially position second orifice plate between a stop shoulder of second head and a lip of second mounting ring. Second feed screw may include a plurality of flights arranged in a split flight configuration including one or more ingress end flights and one or more egress end flights.
