according to the coalition for eco-efficient comminution, comminution the process of crushing and grinding ore is by far the most energy consuming step in the mining process.
copper ore grinding in a mobile vertical roller mill pilot plant. pilot scale vertical roller mill grinding tests were performed for chalcopyrite grinding successfully. showed that vrm was able to grind copper and slag with the energy saving of 22.9% and 34.4% respectively compared to conventional grinding circuits. wear rate is another
energy savings. unlike more traditional ring-geared mill drives where a ring-shaped gear encircles the mill and drives it through one or two pinions followed by conventional motors gmds work by mounting rotor poles directly to the mill body and surrounding it with the stator ring, meaning the mill itself is incorporated into the motor.

the coalition for energy efficient comminution benchmarking comminution energy consumption for the processing of copper and gold ores. abstract ore competence, grind size and ore grade showed that ore grade was the greatest determinate of specific comminution energy. therefore, concentrating the ore via gangue rejection or grade
the attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills energy efficient grinding machines. vertimill energy savings can range from 30% to greater than 50% compared with traditional mills, and the smd energy savings can be far greater than 50% of ball mill energy in fine grinds.
