ABSTRACT:
A method for the production of a fine-grained mixture of mineral solids such as pulverized raw material for the calcining of cement clinkers composed of several materials, one of the starting materials constituting a substantial proportion of the total mixture and having a grain size suitable for further processing, but having a relatively high moisture content, and another starting material also constituting a substantial proportion of the total mixture and consisting of coarse grained fragments. In accordance with the present invention, these two starting materials, together with other additives which might be present, are mixed and suspended in a column of heated air to dry the mixture to a moisture level suitable for further processing.
