In the most general sense, portland cement is produced by heating sources of lime, iron, silica, and alumina to clinkering temperature (2,500 to 2,800 degrees Fahrenheit) in a rotating kiln, then grinding the clinker to a fine powder. The heating that occurs in the kiln transforms the raw materials into new chemical compounds. Therefore, the ...

Limestone, clay and sand are commonly used in making portland cement. In their raw form, these materials contain varying amounts of silicon dioxide. But when they're blended and heated to high temperatures in the cement kiln, the resulting clinker contains new compounds.

Bead Kilns. While many Skutt Kilns can be used to anneal beads the GM10F can be equipped with an optional bead door. The chamber and doors are made entirely of firebrick, not fiber, so it holds the heat when you open the bead door keeping the chamber temperature uniform. It comes standard with a full controller and has the power to reach fusing temperatures.

Pennsylvania RACT is of particular interest because, as noted in OTC's draft white paper (specifically, the Appendix A table entitled "Cement Kilns in CSAPR U and OTR States"), 11 of the 17 Portland cement kilns in OTC states are in Pennsylvania, so OTC's recommendations could have significant impacts on Pennsylvania Portland cement kiln operations.
