Ball Ratio In Milling Process

Best way to determine the ball-to-powder ratio in ball

A general rule of thumb from the CRC handbook on mechanical alloying and milling denotes a 10:1 ratio for small capacity mills (SPEX), but large capacity mills (attritor) can have BPR of 50:1 or

Grinding in Ball Mills: Modeling and Process Control

The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the ratio “length to diameter” and this ratio most frequently varies from 0.5 to 3.5. The
