The vertical velocity of model pressure interfaces can be separated as follows: k ( ). k ppp s tt s ∂∂∂ =− ∂∂ ∂ (23) If the entrainment velocity is zero, the interface vertical velocity equals ∂∂ pt k /, which can therefore be interpreted as the local vertical velocity of a material surface. Since p k and p

This work concentrates on the energy consumption and grinding energy efficiency of a laboratory vertical roller mill (VRM) under various operating parameters. For design of experiments (DOE), the response surface method (RSM) was employed with the VRM experiments to systematically investigate the influence of operating parameters on the energy consumption and grinding energy efficiency.
