Ball mills operate either in open or closed circuit. Open circuit operation is best utilized when: • Another stage of grinding follows the mill • Reduction ratio is small • Feed material is already fine and one pass through the mill produces the desired results • Product size …

· Grinding is the second step of mineral processing and the last stage of the comminution process. The product from a crushing unit is fed to a mill in order to decrease the particle size (sometimes even to 10 microns) for subsequent processing. The reduction ratio is usually large (8 to 25:1 sometimes 500:1).

Provided the original particle size of the solid material is D, after crushing or grinding machine grinding, its material granule size becomes d, the D / d = i this ratio is defined as the material Crusher Size Reduction Ratio, which is the material through a crusher after crushing its size reduction factor.

Crusher Reduction Ratio I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged.

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 π /4.
