The ball mill is the most common ore grinding technology today, and probably more than 50% of the total world energy consumption for ore grinding is consumed in ball mills.

The SAG mill trommel undersize is combined with the ball mills’ discharge and pumped to two parallel packs (clusters) of twelve 660 mm diameter cyclones. The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directed to the flotation circuit. The designed ball milling circuit product is 80% passing 150 µm.

The importance of energy-efficient grinding circuits lies in the fact that Canada has 62 concentrators (Geological Survey of Canada, 2014) of which 70% are located in Ontario, Quebec and British Columbia and 83% of the ore is processed using semi-autogenous grinding (SAG) mills and secondary ball mills.

Karara Mine has decided to shift the comminution workload from the primary ball mill to the TowerMill circuit by bypassing the 100 µm fine screen in between the ball mill and TowerMill circuits. This action has increased the circuit feed particle size distribution with a top size close to 1mm.

circuit is shown in Figure1. It is commonly referred to as a SABC circuit, for Semi-Autogenous Ball mill Crusher (SABC). This circuit shows a semi-autogenous grinding (SAG)/ball mill circuit where both grinding mills are in closed circuit, with the SAG mill closed with a crusher to control the amount of ‘critical size’ material in the circuit.

When calculating rod mill power for a rod mill-ball mill circuit, do not allow for improvement in the ball mill performance. If the rod mill feed is produced with open circuit crushing, apply a 1.2 inefficiency factor to the power calculated for the rod milling stage only. If the rod mill feed will consistently be 80% passing ½" or finer, such ...

The ball mills are transferred in closed circuit with airseparators of various Experience of operation of ball mills suggests that transfer of mill in closed circuit separator. When transferring to closed circuit mill size 2.613 m at a constant quality cement (3000 cm2pg) capacity.

Mar 20, 2020· In this blog you can read there are multiple reasons for measuring density in the grinding circuit. In most sites a ball mill is used for grinding and a (hydro) cyclone for classification. The slurry needs to be continuously monitored and controlled. Density meters efficiently help operators to monitor and control the grinding circuit, optimize it and prevent process failures.

In a ball mill circuit, the "output" can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies. There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill.
