Cement Mill Surface Temperature

Apr 08 2008 in an example that i calculated recently where surface temperature was 54 c the convection accounted for 60 of the heat loss and radiation for 40 for convection the rotation speed the size and even the bolds on the mill play a role since the bolts are really coolers i assumed that you knew the surface temperature by measurement.
