ABSTRACT:
A size reduction machine for use in process industries to continuously and precisely reduce the size of particles, while controlling fines, has a rotatable spindle and a motor operably connected to the spindle for effecting rotation of the spindle. The spindle is mounted within a channel having an input and an output. The size reduction machine comprises a first stage impeller mounted on the spindle, a first screen rigidly mounted within the channel so that particles passing from the input to the output pass through the first screen as the first stage impeller rotates relative to the first screen, a second stage impeller mounted on the spindle, a second screen rigidly mounted within the channel so that particles passing from the first screen will pass through the second screen as the second stage impeller rotates relative to the second screen, a spacer for positioning the impellers along the spindle to maintain a first gap between an edge of the first stage impeller and an interior of the first screen and to maintain a second gap between an edge of the second stage impeller and an interior of the second screen.
