Hence, the coal ash content should be maintained reasonably constant preferably to within about +1 2%. High ash coals, up to 35 or 40% ash content, can be used in cement kilns provided that the ash content is controlled. For coals above about 15% ash content a stockpilereclaim blending system is usually required.

They can take air with 3% oxygen from the preconsigner and feed it to the mill, which normally has an inert atmosphere. Things can go wrong because the oxygen concentration can drop and suddenly go up, and as soon as it becomes more than 12 or 13%, an explosive atmosphere starts. The only thing missing is the ignition source.

Therefore, energyefficient grinding technologies have become the main focus of the industry, especially in the cement industry with largescale plants. Until now, various types of crushing equipment have been developed to meet the requirement of the industry, such as jaw crusher, cone crusher and vertical roller mill, VRM [ 3, 4, 5 ].
Having purchased the LOESCHE stateofthe art vertical roller mill for the grinding of cement, Cementos San Marcos decided to supply another VRM for the grinding of coal. Up to date, the LOESCHE Mill type LM +2 is the sole vertical roller mill in this plant for cement grinding.
The ball mill trunnion plays a crucial role in the efficient operation of cement mills, autogenous mills, and coal mills. As a key component, the mill trunnion provides support to the mill shell and ensures proper alignment, allowing the mill to function effectively.
