The important of crushing your ore and rock fine and properly is often forgotten. The finer you crush, the higher your ball mill tonnage and capacity will be. The effect of ball mill feed size and how it affects circuit throughput can be hard to estimate. Here we described a method of designing a crushing plant using power drawn and power rate to define reduction ratios in each stage of crushing.
Hummingbird Resources is installing a second ball mill at its Yanfolila gold mine in southern Mali to increase plant throughput capacity from 1.24 million metric tons per year (mt/y) to 1.4 million mt/y when processing a blend of ore types.

Mill Speed . No matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation. Too low a speed and little energy is imparted on the product.
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
There are 3 ball mills in our plant so we should differentiate between ball mill power and total power of ball mills which is sum of each ball mills power. By increasing throughput the mill power will increase too but it will also let us to send one of ball mills as a standby so total power seems to .
The second ball mill will increase throughput capacity from 1 Mt/y to 1.24 Mt/y when operating at fresh ore and from 1.2 Mt/y to 1.4 Mt/y when processing a blend of ore types, according to Hummingbird.
Reduce downtime, save on energy costs and increase throughput and capacity in your SAG mill. ... SAGwise TM reduces your mill's ball-on-liner impacts with up to 45 per cent, which prolongs liner life and minimises media degradation. Further, it reduces energy consumption by up to six percent.
