  UNITED STATES PATENT OFFICE 2,186,792 CEMENT MANUFACTURE George C. Wilsnack, Easton, Pa., assignor, by direct and mesne assignments, of one-half to Edison Cement Corporation, New Village, N. J., a corporation of New Jersey, and onehalf to Binney & Smith Company, New York, j N. Y., a corporation of New Jersey No Drawing. Application May 12, 1937, 150-200t/h stone crushing plantSerial No. 142,322 8 Claims. (CL 106-24) This invention relates to an improved process for the production of Portland cement. It relates more particularly to a process by which the cost of reducing the rw clinker from the kiln to the fine powder wh Ites ordinary Portland cement may be greatly reduced, or by which the particle size of the Portland cement may be greatly reduced. By this process, Portland cement which has a particle size substantially smaller than that of ordinary Portland cement and hence has an increased specific surface and improved properties may be readily prepared.
  
  This Portland cement contains a dispersing or separating element or agent which not only ef13 fectively promotes the efficiency of the grinding operation, but also improves the properties of the cement,150tph mountain rock crushing plant in Russia the dispersing or separating element or agent serving to make the cement particles more available for hydration; and this improved Portland cement may be advantageously used for the production of concrete in mixes requiring substantially less water and having a finer texture and better working properties, with the production of a denser concrete which is stronger and less permeable and has fewer voids, and which contains no added agent which might tend to leach out or to deleteriously effect the cement or concrete made therefrom.
  
  Portland cement is commonly made by crushing together argillaceous and calcareous materials in definite proportions and passing the resulting mixture through a rotating kiln in which the pulverized material is subjected to high temperatures.200mesh dolomite powder grinding plant in Indonesia The material leaves the kiln in the form of a clinker, which is then ground to a fine state of subdivision to form the ordinary Portland cement. Before this grinding operation, a small amount of gypsum is generally added to adjust the S03 content of the final product to give it desirable setting characteristics.
