Crushing Energy Efficiency
According to one estimate, the mining industry consumes 12EJ per year of energy – or 3.5% of total final global energy consumption.1 The energy intensity of mining is also predicted to increase over time as deposits that are lower quality, deeper and more difficult to extract are mined.
Size Reduction | SpringerLink
A ball mill consists of a cylinder, which is filled with 30–35% of its volume by small steel balls and is rotated through motor. When the cylinder starts to rotate, the balls start to lift under centrifugal and frictional forces and fall back into the cylinder and onto the feed as gravitational pull exceeds those forces (Fig. 6.5 ).
