Feed Size Distribution In Crusher. Apr 07, 2020 Feed should always be well graded with no gaps in the size distribution, which generally means an even distribution of different-sized feed material up to the defined maximum size. Fines for example, 04 mm should be screened out before the material is fed to the crusher as the fines may cause packing this is a force overload and can be seen as
