    GPC is heated indirectly in the vertical shafts as the coke mass moves down slowly. Unlike in rotary kiln calcining, the GPC is not exposed to the flames during the process. Due to indirect heating and lower air oxidation, the average conversion efficiency of CPC:GPC in a shaft is better than in a rotary kiln and varies from 80

  • Vertical Shaft Kilns (VSK) vs. Rotary Kilns SIME Ing.

    There are two main types of kilns to produce cement: the Vertical Shaft Kiln and the Rotary Kiln. The Vertical Shaft Kiln or VSK is probably the first type of kiln that was used and it can be traced back to the 5th century A.C. in Greece, when they were used for limestone calcining (Reiter, AC, 11/1997, p. 23). In the 20th century,

  • Lime kiln Wikipedia

    A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide). The chemical equation for this reaction is. CaCO3 + heat → CaO + CO2. This reaction takes place at 900 °C (1650 °F at which temperature the partial pressure of CO2 is 1 atmosphere),
