what should be max temperature cement mill discharge

What s the normal operating temperature of bearings
· That would seem to argue 250F as an max upper limit for actual bearing metal temperature. If temperature may be monitored on housing we have to reduce our limit another 15F or so to account for limitations of our monitoring. In our plant housing temperatures on most motor bearings are 130F or below. Occasionally after greasing some go to 180F

Why Concrete Temperature Testing Is Important During
· Why Concrete Temperature Testing Is Important During Extreme Weather. The heat produced by concrete during curing is called heat of hydration. This exothermic reaction occurs when water and cement react. The amount of heat produced during the reaction is largely related to the composition (Table 1) and fineness of the cement.
