Section snippets Experimental work. The same lots of Portland cement clinker and natural gypsum (CaSO 2 O) were used in this industrialplantscale experimental work to eliminate the potential effects of variations in the feed to the grinding systems. Chemical compositions of the clinker and the gypsum, measured by Xray fluorescence analysis, are given in Table 1.

The Tovarov grindability index is used to determine the influence of materials on the cement clinker grinding capacity of a mill; the basis is rotary kiln clinker with a defined grindability index of a = 1. According to this, a mill grinding 30 t/h clinker, will grind 30 x = 42 t/h of marl or 30 x = 18 t/h of silica sand.

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 ...
