ball mill is used as a grinder of cement clinker which is horizontal cylinder type mill. A ball mill is filled with the steel balls that rotate on the axis of mill which has tumbling and cascading actions on the balls. Impact forces cause the crushing of material in the horizontal cylinder. Clinker is grinder with impact and friction forces inside the cylinder. Grinding media which is usually called as grinding balls are made up of high chromium steel. A cement mill is the comminution machine which is used to grind the hard and big sized clinker that comes from kiln section of cement industry into the fine optimal powder which is called as cement. Most of the cement in this world is grinded in ball mills and as well as in vertical roller mills which is always considered as more effective than ball mills. Ball mill is divided into two chambers generally called as 1st and 2nd chamber respectively. This is decided on the basis of the size of feed input. Roller press mills usually has single chamber. These two chambers of ball mills are usually because of different sizes of grinding media. Clinker size of over 25mm is grinded in the first chamber which has large balls. Here the ball mill diameter is in the range of 60-80mm. This grinding is also called as coarse grinding. In the second chamber, the grinding media or grinding balls has a size of 15-40mm. Here the clinker from the first chamber is grinded to the finished product which is called as cement. This grinding is also called as fine grinding. 

Implementation of optimization measures

1. Increased grinding media piece wt. in 2nd chamber.

2. Reduced separator seal gap.

3. Regular cleaning of both the diaphragms during schedule maintenance.

4. Repairing of separator fan casing wear/puncture portion.

5. Reduction of gypsum and Lime stone sizes.

6. Sorting of deformed grinding media from 2nd chamber.

7. Regular cleaning of separator guide vanes.

8. Increased of mill ventilation.
