(PDF) Effect of circulating load and classification ...

CONCLUSION The circulating load and classification efficiency can have a significant effect on the performance of both closed ball mill and HPGR circuits. This is a well-known fact for ball mill circuits that has been recognised for almost 100 years. For HPGR circuits the knowledge is more recent, and is still being investigated.
