- Describe The Process Of Cement Preparation
The raw cement ingredientsneeded for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale, and bauxite. The ore rocks are quarried and crushed into smaller pieces of about 6 inches. Secondary crushers or hammer mills then reduce them to an even smalle…

The Cement Production Process. Cement kilns are massive cylindrical structures, lined with refractory brick, into which a lime-bearing material and fuel such as coal or gas is fed. There is a range of different kiln designs but all rely on the same basic processes — raw feed passing through the kiln is heated to very high temperatures by the ...

The paragraphs below briefly describe the process, starting with the wet process and then noting differences in the other processes. In the wet process and long dry process, all of the pyroprocessing activity occurs in the rotary kiln. Depending on the process type, kilns have length-to-diameter ratios in the range of 15:1 to 40:1.
