Mill capacity is dependent on: 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 ...


Grindability - an overview | ScienceDirect Topics

The higher the HGI the lower is the power requirements, and the finer the particle size. HGI represents a fuel that is easier to grind. An HGI-measuring machine is a miniature ball mill type of pulverizer. Herein, a standard mass (50 g) of coal is grounded for a given time in the mill subjecting the balls to a known force.
