How to Perfect China Cement Mills Successfully?

The implementation of the new cement standard requirement for the quality of cement machinery has improved further, especially the new dry process cement production line is called the development of cement industry mainstream after grinding technology is much more attention, this causes the cement grinding technology to keep pace with The Times.So cement grinding technology of China cement mill for modification should be how to operate?

(1) open closed circuit grinding process of choice Cement grinding process of open and closed circuit choice, is actually the particle size distribution and the selection of cement strength. Closed-circuit grinding product fineness and temperature can be controlled, avoided the transition gypsum dehydration, and closed-circuit grinding is suitable for many kinds of cement production, strong adaptability to the water of materials.According to experience, mill diameter less than 3.2 m, can adopt open already, also can use closed circuit process; China cement mill is greater than or equal to 3.4 m in diameter, suitable for closed circuit process.

(2) a large ball mill grinder closed-circuit system, after the large-scale ball mill, the original use of efficient classifier closed circuit in actual application of production technology will cause the accumulation of dust, shell, such as blade wear, and the solution is to adopt mill ventilation dust collecting system is separated from selected powder system of new technological process, at the same time adding grinding efficient static separator.

(3) whether long grinding of cement equipment is suitable for closed circuit After the implementation of the new standard of cement, because the improvement of cement quality requirements, and length to diameter ratio of 3-4 of 4 or more midfielder captain grinding is also suitable for closed-circuit grinding.Materials in grinding time may be extended appropriately, which is beneficial to increase the quantity of fine powder, and improve...
