    The finest coarse-aggregate sieve is the same No. 4 used as the coarsest fine-aggregate sieve. With this exception, a coarse-aggregate sieve is designated by the size of one of its openings. The sieves commonly used are 1 1/2 inches, 3/4 inch, 1/2 inch, 3/8 inch, and No. 4.SCREEN CAPACITY CALCULATION VIBFEM,complex screen capacity calculations in much shorter time. This allows for the inclusion of more and more subtle factors, which greatly increase the accuracy of the conclusions. Increased accuracy will reduce the under or over sizing of screens. Un-dersized screens cause carryover or reduced plant output.
