2) Wet Process - Feed materials for the wet raw grinding circuit may involve materials stored relatively dry and, in the case of previously processed clay, in "slip" form at perhaps 60% - 70% moisture content. Emissions from the transfer of dry feed components to the mill are normally controlled by low temperature bag-type collectors.

2.2-2 Shorter flames are too hot and cause refractory damage and overburned lime, while longer flames cause some loss in production capacity and efficiency, and loss of control of the product quality. A compact, medium-length flame approximately three times the kiln diameter in length is a good tradeoff between efficiency and refractory service
