Function: A cement mill is a drive 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. Process: Raw materials are fed to the mill in right proportion with the help of weighfeeders.

Pebble mills are a type of ball mill and are also used to reduce the size of hard materials, down to 1 micron or less. Because of their fairly simple design, ball mills and pebble mills are less likely to need costly repairs (unlike other crushing or extraction equipment) making them an attractive option for businesses on a budget.

Havre in France. In the first few years, the GMD was only used in the cement industry. The GMD is also known as “wrap-around motor” or “ringmotor”. Almost 25 years later, the first GMD with 12.0 MW power and 13.0 rpm was installed in the minerals industry. Since then, numerous GMDs for ball mills and SAG mills have been installed in the

1. The basic strength and rigidity of the ball mill are insufficient. During the transformation process, many cement plants directly converted to closed-circuit systems through open-circuit systems, ignoring the foundation of the ball mill equipment, resulting in vibration of their main bodies. In this case, the cement plant can solve it by ...
