In the past the conventional method of driving large ball mills included some form of speed reducing gear between the higher speed driving motor and the lower speed ball mill. Process developments in the mining and cement industries have increasingly tended toward the use of ever larger ball mills for grinding their products. As the horsepower drive ratings required have …
Raw mill is also called cement raw mill, similar to cement ball mill, it is an important cement milling equipment used in the cement production process. Raw mill is mainly used for grinding cement raw meal in the cement factory production process. It is also suitable for metallurgical, chemical, electric power and other industrial mining enterprises to grind various ores and other …
Cement Mill; Go back to Contents Table ↑ 5.3 Variable Speed Drives (VSD) In the last 25 years, variable speed drives (VSD) have been used more frequently in the cement industry. The main reason was to save energy in the production process. Generally speaking, variable speed motors would be used for electric motors listed in Table 1 below.
The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time

To run the mill at full speed, Ash Grove uses a synchronous motor starter, which does not have any speed control. "With over 30 years of experience in the cement industry, I consider myself a DC devotee," said Wright.
The upper limit is decided by the requirements of the applications rather than by the technology of the converters and machines (Stemmler 1994). The available speed range lies from 10 rpm for low-speed machines (e.g. Cement mills), 1500/3000 rpm for normal-speed drives to even 18 000 rpm for very high power high speed drives (e.g., compressors).
