• The Schoefer Kilns Historical Marker

    Jul 05, 2015 · It is made by burning various minerals in a kiln at intensive heat to produce clinker. The upright dome kiln was the first type used in America. An improvement was the Schoefer vertical kiln with chambers for heating burning and cooling the material. The kiln was in continuous production except when closed for repairs. Bituminous coal served as ...

  • Clinker: reactions in the kiln

    Reactions which take place as the feed passes through the kiln are reviewed below. They can be considered under three broad headings: Decomposition of raw materials temperatures up to about 1300 °C. Alite formation and other reactions at 1300 C1450 °C in the burning zone. Cooling of the clinker.

    For instance, a regular clinker at 1450 ºC has a viscosity of /m 2 . Adding 2% SO3 to the clinker reduces that viscosity to /m 2. Oversulfated clinkers are usually dusty as a consequence. Extreme caution should be exerted when insufflating calcium chloride into the burning zone as a way to reduce alkali in the clinker.

    A rotary kiln of 6 x 100 m makes 8,000–10,000 tonnes per day, using about tonnes of coal fuel for every tonne of clinker produced. The kiln is dwarfed by the massive preheater tower and cooler in these installations. Such a kiln produces 3 million tonnes of clinker per year, and consumes 300,000 tonnes of coal.
