Cement Rotary Kiln International Cement Review

2014-2-5  Question-6: Generally calciners (in cement books) classify to three types: In-Line calciner, Off-Line calciner & Separate-Line calciner. The definitions of these three types are as the following: 1. In-Line calciner is installed in the kiln exhaust gas flow which means that the combustion takes place in
