    摘要： A diaphragm in the form of a composite sieving device for use in a rotary grinding mill containing loose grinding bodies for grinding solid materials is disclosed. The device comprises a sandwich structure which includes a plurality of plate-like members in intimate contact with one another. The plate-like members acting in combination prevent the passage of the grinding bodies and oversized particles of the material being ground from one section of the mill to another.

    摘要： Hydraulic cement of very high strength is ground to a fineness corresponding to a specific surface of 6,000 cm. 2/g. or more as measured by the Blaine method by grinding the clinker to the fineness of ordinary Portland cement, cooling the cement to about room temperature and then grinding the cooled cement by small grinding bodies having an average weight of no more than 6 grams.

    摘要： A continuous output of very fine grain size mineral material is obtained in a mill grinding operation by initially grinding material to have a residue below 10 percent on a 210-micron screen, then further grinding the material by means of grinding bodies having a maximum middle or average weight of less than 15 grams until a product of a fineness below 1 percent on a 210micron screen is obtained and then the product is passed out of the mill by gravity or overflow through an opening at the outlet end of the mill.
