History of Portland Cement in the United States

The wagons were drawn up an incline by a cable to the second floor of the cement mill. Here the clinker was stored until it was needed on the first floor where it was ground and packaged. These vertical kilns of mill B still stand today serving as the David O. Saylor Cement Museum.

Manufacturing Process – Continental Cement

The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls tumble and crush the clinker into a super-fine powder. It can now be considered Portland cement. The cement is so fine it will easily pass through a sieve that is fine enough to hold water.
