Energy Benchmarking - SMC Testing
2021-6-19 As the survey of the comminution circuit measures the operational power draw (kW) and throughput (tonnes/hr), ratioing these two values gives the actual specific energy of the circuit. If this actual value is higher than the Morrell Method standard value then there is a potential for improving the energy efficiency of the circuit.

Is progress in energy-efficient comminution doomed ...
2015-3-15 Comminution is known to be an inefficient user of energy. This makes it the largest energy consumer in many mine sites and therefore a large component of cost. One would therefore have thought that improving comminution energy efficiency would be receiving the undivided attention of the mining industry, but this is not the case.
