Abstract
A process for preparing nodules of raw cement consists in mixing at least one of the raw materials with an organic liquid and then adding water applied either directly or mixed with the other ingredient. The water drives off the organic liquid almost entirely. The organic liquid is such that it does not react chemically with the raw materials, is insoluble in water, and has a specific gravity different from that of water, e.g. crude oil, paraffin oil, or benzol. All the raw materials may be mixed with the organic liquid and water subsequently added, or one of the ingredients may be made into a slurry with the organic liquid and the other with water, the two slurries being then mixed. In an example, clay and lime are ground together with an organic liquid and then while the material is being stirred, water is added as a spray so that nodules are formed and the organic liquid is expelled. The material is then extruded by a press into a continuous length which is cut up into suitable nodules. These may be dried by the waste gases from the kiln. In another example, the clay is ground wet with all the water required in the finished nodules and the lime is ground with organic liquid. The two slurries are then mixed, with the result that the water expels the organic liquid almost entirely, and nodules are formed. The material is then extruded as in the first example.
