Ball mill - Wikipedia
An underloaded mill will have sub-optimal milling performance and accelerated media wear. Scale Up - Experimentation on a small laboratory scale jar rolling mill is possible as long as scale-up is considered. Ball milling is one of the few unit operation that improves with increasing mill diameter.
Operation 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
