The production of cement can be divided into dry process and wet process, while because of the high output, low heat consumption and steady running, the dry process has become the most commonly used manufacturing method in cement plant, mainly includes three models: dry process rotary kiln production, suspension preheating kiln production, and ...
The major advantage of this process is that the kiln can be far shorter – usually only around 70m long. So, factories can install twice as many kilns in the same area that would be needed for wet processes, greatly increasing output. The Vital Role of Kilns in Cement Production. The kiln is the heart of the cement-making process.
