Gelatinization occurs by mechanical means such as grinding, pressure, and by hot water. Soft feed at an environmental temperature of 25°C can be brought to a temperature of 85°C by the addition of 4 to 6 percent moisture from steam. Frictional heat due to passage of feed through the pellet mill adds 2 or 3 degrees of temperature.

2. In a reverse closed-circuit ball mill-classifier circuit the new feed enters the classifier, the classifier oversize is fed to the mill, the mill discharges to the classifier, and the classifier undersize is the finished product of the grinding circuit. The following are the sieve analyses of the streams of such a circuit.
