- How To Calculate Material Residence Time In A Vertical Roller Mill
The advantage of the vertical roller mill for cement (comparison with the tube mill) 1) Highly efficient grinding is possible with considerably low electrical power consumption. 2) The residence time of cement grinding in the vertical roller mill is much shorter than that of tube mill. Since system operational control response is superior,

There are few studies concerning the process simulation of vertical roller mills (VRMs). In this research work, the application of population balance model for simulation of a VRM in a cement clinker grinding circuit was investigated. The residence time distribution (RTD) was measured, and the tank-in-series and Weller models were employed to describe the residence time …

This is the instantaneous residence volume for pulp. Next compute the volumetric flow of slurry into your mill, as m³/h or L/s (match whatever volume units you used in the first step). Now divide the instantaneous volume by the vol flow (cancelling the vol units) and you are left with time units; this is your residence time.
