Energy Consumption in Mining Comminution

which are energy intensive and use the world’s biggest pumps in their main production process. The distribution of energy at a mine site is 3 5% for blasting, 5 7% for crushing, and 80 90 % for grinding [10, 11]. Energy consumption occurs everywhere in the mining and manufacturing sectors. For relevance in energy consumption,

Iron ore grinding process,process design for grinding

The grinding efficiency is low, the energy consumption is high, and the product is easily crushed, which affects the sorting effect and economic benefits. Practice has shown that the more difficult to grind the ore, the less economically reasonable it is to use one-stage grinding process for fine grinding.

Research of iron ore grinding in a vertical-roller-mill

The total energy consumption for ore comminution will further increase within the next decades. One contribution to minimise the increase is to use more efficient comminution equipment. Vertical-roller-mills (VRM) are an energy-efficient alternative to conventional grinding technology. One reason is the dry in-bed grinding principle.
