how can impact of l d ratio on cement ball mill

Fiber-reinforced concreteWikipedia
Increasing the aspect ratio of the fiber usually segments the flexural strength and toughness of the matrix. However fibers that are too long tend to "ball" in the mix and create workability problems. Some research in the late 2000s indicated that using fibers in concrete has limited effect on the impact resistance of the materials.

ATTRITORS AND BALL MILLS HOW THEY WORK Robert E.
Ball mills are one of the more common mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades. A typical ball mill has an L/D ratio of 1.5 1. Ball mills are filled with spheres or other shapes made of steel or ceramics or with pebbles made of flint (or of an ore being ground).
