Cement production can also be enhanced by Industry 4.0 in a number of ways. (See Exhibit 1.) In particular, 4.0 solutions can better manage the enormous energy consumption, rising cost challenges, and overall process complexity that are inherent to the industry. For instance, cement companies today must rely on engineers' gut feel and …
In dry and semi-dry processes for cement manufacturing, the raw materials will be crushed and then fed in the correct proportions. It is then added to the grinding mill. Then, the raw material will be dried and reduced in size to a fine powder in there. The dry powder you will get there will be called the raw meal then, the raw meal will be ...
