2021-5-14  If your product size needed is 100% passing 45 micron, then the ball mill total discharge material will contain normally 30% of 45 micron. The rest is oversize which has to be ground again. When this load is passed to classifier you may get only 20-25% product, the bypass of 5-10% (R45) comes back to mill as rejects.
