FL ball mill for cement grinding

An internal water cooling system may be installed in one or both grinding compartments to optimise mill perform- ance and to ensure an appropriate material temperature inside the mill and at the mill discharge end. If the materials to be ground contain more water than can be dried off in the first compartment, the mill will.

A false air rate of -15 [%] has to be considered between mill outlet and fan. This results normally in air temperature of 5 [°C] below cement temperature at mill discharge. Higher temperature differences point to higher false air rates. ♢ The mill exhaust air temperature must always be kept > 30 [°C] above the dew point.
