Control of product quality. In addition to control of temperature (mentioned above), the main requirement is to obtain a consistent fineness of the product. From the earliest times, fineness was measured by sieving the cement. As cements have become finer, the use of sieves is less applicable,Cement mill - Hengin Heavy,parameters The technical characteristics of large cement mill developed and designed by CITIC-HIC plant are as follows: The transmission forms adopted by the drum mill are edge transmission, center transmission, multi-point meshing edge transmission, etc.; the driving forms are asynchronous motor + reducer + pinion + girth gear and synchronous motor + air clutch + pinion + girth gear;OPTIMIZING THE CONTROL SYSTEM OF CEMENT MILLING:,Mill Feed Sep.
