Abstract
A method and apparatus for burning cement clinker from differing mineral base materials. One of the base materials has a relatively high proportion of components which form melt phases at a predetermined temperature and another base material has a relatively slight proportion of such components. The two base materials are separately thermally pretreated. The base material higher in melt phases is at least partially melted after thermal pretreatment and is introduced into a clinker reactor in its molten state together with the thermally pretreated base material which is lower in melt phases and still exists in the solid phase. The mixture is heat treated and finish-burned into clinker in the clinker reactor. The invention also comprehends apparatus for performing the method of the invention.
