    WE’RE ON FIRE FOR THE MOST EFFICIENT LIME KILNS

    The principle of the PFR kiln, i.e., the calcination of lime in one shaft and the preheating of the stone with the hot kiln gas in the other shaft, is also used in the Finelime kiln. Thus its heat consumption is significantly lower compared to rotary kilns. Since 1989, when it was first introduced onto the market

    Lime Production: Industry Profile

    Lime kilns can be categorized into three groups: rotary kilns, vertical kilns, and miscellaneous. About 90 percent of commercial lime capacity in the U.S. is calcined in rotary kilns. Most of the remaining capacity is processed with vertical kilns (vertical kilns are more common in captive supply facilities), and small quantities are processed

    The next most common type of kiln in the United States is the vertical, or shaft, kiln. This kiln can be described as an upright heavy steel cylinder lined with refractory material. The limestone is charged at the top and is calcined as it descends slowly to discharge at the bottom of the kiln. A primary advantage of
