high recirculating loads in ball mill circuits - grinding

high recirculating loads in ball mill circuits - grinding

The ball mill has higher circulation load, it generates only 30 -35% of actual fines you require to be called as product. 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
