This video on Power-Based Modelling is the sixth in the SMC Masterclass series on comminution.

As distinct from the energy-size models in power-based modelling, power models relate the dimensions and operating conditions to the power that they draw. Such models are used in conjunction with energy-size models to arrive at the correct choice of equipment when designing a comminution circuit. This masterclass introduces some of the history of power modelling and describes in detail Morrell’s power model for tumbling mills. This masterclass will be particularly useful for those taking advantage of the on-line power draw tool that can be accessed via SMC Testing’s website at
