The mill is used primarily to lift the load medium and charge.Additional power is required to keep the mill rotating.3 power drawn by ball, semi-autogenous and autogenous mills a simplified picture of the mill load is shown in figure 8.3 ad this can be used to establish the essential features of a model for mill power.
Residence time calculator.Calculate the residence time from given flow velocity and bed height.Fill flow velocity together with bed height and hit the calculate button to calculate the residence time.Hit reset button to clear the fields.
The residence time of the liquid is the ratio of occupied vessel volume, at the required level, divided by the liquid flow rate.Liquid hold-up depends on the service, for example, whether it is to be used as a reflux drum, or if it is intended to allow separation of water from hydrocarbons, etc.
