    摘要: A method is shown for producing a lightweight aggregate by treating flyash and sewage sludge. The flyash and sewage sludge are mixed together and then agglomerated into pellets, with or without the use of a binder. The pellets may be coated and then are dried. The dried pellets are introduced into a rotary kiln in a direction that is co-current with the flow of fuel and air through the kiln. The pellets in the kiln witll be indurated and will experience complete calcination as well as varying degrees of pyrolizing and sintering. The product of the kiln is a nodular material having a low density but with a hard and porous structure. The product of the kiln is feed to a cooler. The flyash sewage sludge mixture has a significant fuel value that is usable in the kiln. Furthermore, the fuel value available in the kiln off-gases may be used for drying the materials.

    摘要: A device for cooling the opening of a rotary kiln via cool air-blowing, the kiln including a metal cylinder lined internally with a refractory material and being rotatably mounted relative to the frame of the kiln, into which materials are intended to be inserted and fired. The cooling device includes: the aforementioned cylinder and a metal cylinder end part covered with a refractory material and secured to the cylinder; two concentric metal casings, known as the inner and outer casing, which surround the cylinder of the kiln and form two annular channels; and ventilation elements that allow cool air to flow through the annular channels. The device includes: an annular distribution chamber which surrounds the cylinder, is secured thereto and supplies the first channel with air; ventilation elements including at least one fan and an electric motor actuating the fan, and supplying the distribution chamber in an air-tight manner.

    摘要: A cooler (6) for cooling of particulate material which is subjected to heat treatment in the rotary kiln is mounted at the material outlet end (1) of a rotary kiln. The cooler is provided with annular chambers (7, 8, 9) disposed around each other, and which are successively passed by the material from the outlet (5) of the kiln to a material outlet (20) in the stationary housing (15) of the cooler in countercurrent with the cooling air which flows from an air inlet (18) and through the annular chambers to the kiln in which the air thus heated is utilized as combustion air.
