rlhe method set forth in claim 1, in which the relative humidity of the air is reduced below that of the atmosphere by heating such air to a temperature above atmospheric temperature.rllhe method set forth in claim 1,Calcium carbonate powder production line in which the relative humidity of the air is reduced below that of the atmosphere by heating such air to a temperature above atmospheric temperature, and in which the clinker being ground is also maintained at a temperature above atmospheric temperature.The method of grinding Portland cement clinker to a fine State of division while preventing deleterious elfects upon the setting properties of the ground cement which comprises subjecting the same to a grinding operation in an enclosed chamber, and introducing air of low relative humidity into such enclosed chamber during the grinding operation.
Y5. The method set forth in claim 4, in which the air is heated before introduction into said enclosed chamber so as to lower the relative humidity thereof.`The methodset forth in claim 4,Chrome ore processing plant in which the air is heated before introduction into said enclosed chamber so as to lower the relative humidity thereof, and in which the clinker to be ground is also heated before introduction into said enclosed chamber so as to prevent the air from being cooled below the dew point thereof during the grinding operation.
The method of preventing deleterious action of atmospheric moisture upon Portland cement clinker during the grinding thereof,Coal &pet coke crusher and grinding mill for sale which comprises conducting the grinding of such clinker in a gaseous medlum of lower relative humidity than the atmosphere.1n testimony whereof 1 have hereunto subscribed my name this 27th day of May, 1927.
