A: Forging reduction is generally considered to be the amount of cross-sectional reduction taking place during drawing out of a bar or billet. The original cross-section divided by the final cross-section is the forging ratio (say 3:1). There is an equivalent reduction on upsetting for forgings being upset during forging (gear blanks, for example).

Generally, every crusher machine is not the same, here are several common crusher size reduction ratio: The impact crusher size reduction ratio is 20 to 1. The vertical shaft impact crusher size reduction ratio is 4-8 to 1. The vertical roller mill size reduction ratio is 2-2.5 to 1. The hammer crusher size reduction ratio is 20 to 1.

Mill Characteristics (length, diameter, rotation speed, lifters) Feed Characteristics (work index) Reduction Ratio; Under given load and particle size requirement, capacity is a function of mill length and diameter: Q = kLD 2+N. N is related to mill diameter which decreases with larger diameters k a constant equal to Ï€ /4.

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical
