Measuring Ball Mill Ventilation Gcp Applied Technologies
May 09, a simple check for the degree of false air is to compare the mill cement exit temperature with the mill gas exit temperature. as the cement and gas leave through the mill exit at the same temperature in a well-sealed system, the difference in these two temperatures will be only a few degrees. if the temperature difference is in excess of 10 c, then this is an indication of excessive false air. note: the gas temperature will never be higher than the cement.

The mill is designed to handle a total ball charge of 324.5 t at 100% loading with a percentage filling of 29.5% in both the chambers. both the chambers of the cement mill were charged with 80% of the designed.
This is done by a mixture of both air-cooling and water-cooling, including spraying water inside the mill. cement milling and gypsum dehydration. because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of paris - 2caso 4.h 2.
Water spray in cement mills. water spray installed generally in second compartment of ball mill to control cement temperature. cement discharge temperature should be kept below about 110 o c but, the same time should allow some 60% dehydration of gypsum to optimize cement strength without excessive false set. water spray is controlled with mill outlet gas or material.
