  • Cement Plants: Oil

    The only use of oil was in white cement manufacture where a zero-ash fuel was required. However, in the 1950s, the relative price of oil steadily fell. In the late 1950s, a large number of cement plants converted from coal to oil firing. The economic justification for this was marginal, but politics also played a major part in the decision-making.Cement kiln Wikipedia,Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.

  • Cement Kilns: Early rotary kilns

    Its immediate precursor was the “black ash cylinder” of the alkali industry. The black-ash cylinder was a batch process, otherwise similar. It is interesting to note that the Navarros, who first successfully used a continuous rotary kiln for portland cement, had in 1886 operated a batch-process rotary furnace for burning “natural” cement.,
