The moisture content of raw materials in semi dry process is reduced, and the unit heat consumption of clinker can also be reduced by 837 ~ 1675kj / kg (200 ~ 400kcal / kg) compared with that of wet process. Because the grate heater is used to replace part of the rotary kiln to dry the material ball, the rotary kiln can be shortened.

The cement kiln
The milling process generates heat and excessive mill temperatures are undesirable. It is clearly helpful, therefore, if the clinker is cool as it enters the mill. From an environmental and a cost viewpoint, the cooler reduces energy consumption by extracting heat from the clinker, enabling it to be used to heat the raw materials.

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.
