Methods and systems for controlling a cement finishing mill, and operating the mill at an optimal point, are disclosed. To determine an optimal point of operation, values of mill power and sound are collected and compared to values predicted by a model to determine if the mill is choking. This choking determination is used in one of two processes to determine an optimal point of operation for ...

For determining the proper mix, one has to divide the constant 44 by the sum of the parts of cement, the parts of sand, and parts of gravel to determine the number of bags of Portland cement required. Then the number of bags of cement has to be multiplied by parts of sand and the constant to calculate the number of cubic yards of sand needed.

As a rule of thumb, the residue on 90micron sieve should not be less than half of the volatile content for safety purpose. ie. R90>=1/2. Volatile Content %. Coal Moisture: The degree of drying, and therefore the required mill outlet temperature (from 6580 0 C) will depend upon the type of coal ground. Some residual moisture in fine coal is ...
