The Small Pebble Process for Reducing Ball and Power Consumption in Secondary Grinding . Ball mills are used widely for secondary grinding. A mixture of ball sizes can be used to optimise grinding efficiency, but the use of balls smaller than about 30 mm in diameter is not normally viable, particularly when alloy steel is required.

mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential ...

May 01, 2017· The power consumption of a ball mill is one of the most important parameters to consider in the design of a ball mill because it determines its economic efficiency. The power consumption is usually determined by charge fill level, lifter height, lifter number, and mill speed. ... thereby reducing the mill power.

When the feed rate of the ball mill is increased or the grinding rate is required to be too fine, the service efficiency of the ball mill wear-resistant grinding media ball is in a lower range, thus increasing the power consumption of the ball mill and increasing the damage rate of the wear-resistant grinding media Ball.

A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

See this useful summary Table of Bond Work Index by Minerals. For any circuit, whether a crushing circuit, a rod mill, or a closed ball mill circuit, the Work Index always means the equivalent amount of energy to reduce one ton of the ore from a very large size to 100 um.

The second chamber of a ball mill is mainly for fine grinding. Therefore, using small balls was known to be more efficient as this increases the surface area of media and improves the grinding effect. For the conventional mill using a liner with lifter, however, it was difficult to reduce the ball diameter drastically because the grinding efficiency is extremely lowered by reverse ...

Vertical roller mills (VRM) can replace ball mills or tube mills used for preparing coal. Today VRMs with capacities up to 50 tph are the dominant technology for coal grinding. According to MIIT, grinding media wear in a VRM will only be 5 to 10 g/ton of coal powder, as compared to 100 g/ton of coal powder in a ball mill.

A typical comparison of three competing technologies is given in Table 1, demonstrating that an efficient ball mill/third-generation separator, CKP/ball mill/third-generation separator and vertical mill on a typical 4000Blaine limestone cement show little overall difference in energy consumption.
