    2021-1-27 · Limestone is mainly composed of the compound calcium carbonate (CaCO 3). Limestone is a sedimentary rock which was formed from the shells of sea creatures that lived millions of years ago. Limestone is quarried and can be used to produce cement, glass and concrete. Cement. Limestone is heated with clay to make cement in a rotary kiln.Limestone and Clay BinMaster,Application: The raw mix is fed into a pre-heating tower at 1472°F (800°C) before returning to the vertical rotary kiln where it is heated to a temperature of 2642°F (1450°C).
