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.

The grinding process of the ball mill is an essential operation in metallurgical concentration plants. Generally, the model of the process is established as a multivariable system characterized with strong coupling and time delay. In previous research, a two-input-two-output model was applied to describe the system, in which some key indicators of the process were …

To enhance the electrode performance, the sample was thoroughly mixed with acetylene black by using a planetary ball mill (Pulverisette 7, Fritsch) at 300 rpm for 6 h with a zirconia pot and balls. Thus, obtained carbon composited samples were handled in an Ar-filled glove box to avoid contact to moist air.
