Feb 08, 2021 Abstract Ball drum mills (BDM) are one of the main types of coal-grinding equipment in Russia. A significant drawback of BDM is high power consumption (a significant part of the TPP’s own needs). With a huge scale of production, reducing these costs even by a few percent gives a significant economic effect. The problem of minimizing the specific energy consumption for grinding and.
Scale-up criterion is the net specific power consumption, i.e. the power consumed by the mill rotor itself minus all mechanical and electrical losses divided by the feed rate of solids. For the full scale mill, specific power is multiplied by the feed rate to get the net mill power.

The result an increase in production of approximately 25 percent, and a reduction in specific power consumption of about 10 percent compared to a conventional ball mill system. Semi-finish grinding Upgrading a ball mill system with an HRP in a semi-finish mode is a simple solution, and installation is easy.

Providing operating data for 3 semi -autogenous grinding (SAG) mills and 4 ball mills. Results show on. average that 7 9 of the supplied electrical energy converts to heat absorbed by the slurry.
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.
Dec 18, 2013 This quantity is small compared to the power used by a semi-autogenous mill and a ball mill in a primary grinding circuit a ball mill can have an installed power of up to 15 MW, while installed power for a SAG mill can go up to 25 MW. However, the energy used for fine grinding is still significant.
