Rotary kilns consist of a rotating cylinder inclined at an angle of 3 to 4 degrees to the horizontal. Limestone, chalk or Dolomite is fed into the upper 'back end', and fuel plus combustion air is fired into the lower 'front end'. The product is then discharged from the kiln into a cooler, where it is used to pre-heat the combustion air.
