The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction. Clinker quality depends on raw material composition, which has to be closely monitored to ensure the quality of the cement.
Following methods may be employed to control noise pollution in cement industry. 1. Using vibration damping pads, isolating vibrating parts etc. to reduce noise pollution in cement industry. 2. By enclosing the source and making them sound insulated. 3. Using personal noise protectors like, ear plugs, ear muffs etc.

A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
Cement LEADING TECHNOLOGY IN BALL MILL CONTROL With MILLMASTER KIMA Process Control offers the most robust, open and easy to handle Advanced Control System in the Cement Industry. Since 1996 this 'Auto-Pilot' system was installed in hundreds of cement plants to operate mills fully autonomously.
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 …
