Discrete Element Methods (DEM) is a numerical tool consolidated to the simulations of collisions in particulate systems. In this paper, the method was used to study the collisions between grinding media and grinding media and walls in ball mills, which is the most used unit operation in clinker grinding, the majority component of the cement. Amongst the variables that affect the dynamics of ...

The current world consumption of cement is about billion tonnes per annum and it is increasing at about 1% per annum. The electrical energy consumed in cement production is approximately 110. kWh/tonne, and around 40% of this energy is consumed for clinker grinding.. There is potential to optimise conventional cement clinker grinding circuits and in the last decade significant progress has ...

Cement consists of clinker, gypsum and other components mostly more easily ground than clinker. To minimise overgrinding modern ball mills are fitted with dynamic separators (otherwise described as 'classifiers' or more simply as 'separators'). The working principle is that cement is removed from the mill before overgrinding has taken ...

As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed. However, one drawback with this approach is that ...

Narrow size fractions of a Portland cement clinker and a chromite sample were used as the experimental materials. The size fractions of both samples coarser than mm were used in the singleparticle impact loading tests. Ball mill grinding tests were performed with the narrow size fractions of the clinker sample finer than mm.
