202571· – Ball mills typically operate at 65–75% of critical speed for optimal efficiency. – Below critical speed: Balls cascade (rolling and tumbling), causing impact and attrition grinding. – At critical speed: Centrifugation occurs, halting grinding action. 4. Importance: – Ensures proper cascading motion for effective size reduction.
