Rotary Kiln 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 preheat the combustion air

rotary kiln This is determined by i the maximum flow rate of the proposed burden through a kiln and ii the residence time at temperatures that would allow sufficient reduction to take place A calculation method was developed that allows for the prediction of the bed profile and residence time in a rotary kiln
