The plant adopted for the study has a wet production capacity of 1 million tonnes per year and a dry process output of million tonnes per year. Six operation units are identified for the wet process while five units are identified for the dry process. The operation units con sidered for the purpose of this work include crushing,
Ordinary Portland cement is the cementing material used in cement concrete hollow blocks. Cement is the highest priced material per unit weight of the concrete. Hence, the fine and coarse aggregates are combined in such proportions that the resulting concrete is workable and has minimum cement content for the desired quality.
Now these powdered minerals are mixed in required proportion to get dry raw mix which is then stored in silos and kept ready to be sent into rotary kiln. Now the raw materials are mixed in specific proportions so that the average composition of the final product is maintained properly. Fig: Manufacture of Cement by Dry Process. b) Wet Process
