### Effect of Feed Rock Size Distribution on Crusher Performance

Primary crusher feeds usually fall under the “graded” category, and reduction crusher feeds under the “sized.” Graded feeds may or may not have the under-size removed, depending upon the nature of the operation and of the material. Sized feed for reduction crushers is generally a screened feed which has definite maximum and minimum limits.
