A material separator apparatus for obtaining refined material subjected to a first grind reduction which is moved into the separator where the larger and/or heavier particles of the material are separated out and returned by gravity to fall back into the first grind reduction for further reduction while the finer ground material is subjected to a second separation by a rotary separating device having an array of spaced members which allow the passage of particles smaller than the spacing between members and the larger particles are refused passage and fall back for further reduction.
