### Cement grinding Vertical roller mills versus ball mills

The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the OK mill and the retention time in the mill is shorter, the product will not be heated up as much as in a ball mill.

### Understanding the Difference Between Retention Time and

The use of the relative retention time (RRT) reduces the effects of some of the variables that can affect the retention time. RRT is an expression of a sample’s retention time relative to the standard’s retention time. RRT = Standard RT / Sample RT To measure RRT, a sample matrix is made up by mixing the sample with an internal standard (IS).
