The two milk pipes exchange their heat: the incoming milk is warmed up to about 38°C (100°F), the outgoing ...
The three high rolling mill utilizes the principle of passing the work back and forth to achieve a series of reductions. Unlike the two high reversing mill, the three high mill has three rolls that always spin in the same direction. An elevator mechanism lifts and lowers the work so that it can be passed back and forth through the rolls.
3.
