The L/D ratio of the ball mill was varied in four steps of 1.75, 2.1, 2.79 and 3.49, and the ball charge filling ratio was varied in three steps of 15%, 20% and 25%. The experiments clearly indicated that the optimal L/D ratio and the optimal ball charge filling ratio are different for each feed fineness.

For one compartment mill this ratio is (L/D) =1.5 A two compartment mill has a ratio of (L/D) = 3.0 A three compartments mill has a ratio of (L/D) = 4.5 However, for optimum mill sizing, these ratios of length to diameter must be compatible with grinding requirements.

The aspect ratio (l/d) is calculated by dividing fiber length (l) by its diameter (d). Fibers with a non-circular cross section use an equivalent diameter for the calculation of aspect ratio. If the fiber's modulus of elasticity is higher than the matrix (concrete or mortar binder), they help to carry the load by increasing the tensile strength ...
