    In a hammermill the screen-hole diameter controls the maximum finished particle size of any ground product. When using roller mills there is no screen being used and unless the product is sifted and the coarse fraction reprocessed the resultant particle size is purely reliant on the miller s skill in setting the roller mill effectively.
