Abstract

587,681. Calcining kilns. PRIEST, C. F., and KNIBBS, N. V. S. July 4, 1944, No. 12714. [Class 51 (ii)] A kiln for calcining solid materials, such as limestone with which fuel is mixed, comprises a vertical shaft 27, Fig. 1, fed from a hopper 23 through passages 26 arranged between horizontal gas withdrawal ducts 25 connected to headers and chimney flues. The calcined material is withdrawn from the. base of the shaft through passages 37 between inverted trough shape members 36 perforated at the top for the passage of air and provided with protecting caps 43. The material falls on to spaced horizontal plates 51 from which it is pushed by reciprocating bars 54 into a discharge hopper 59 provided with an air inlet at 46 and a delivery opening 60 provided with a discharge worm 61. In the modification shown in Fig. 8, the inverted trough shape members at the base of the kiln have one side 65 partly vertical and partly inclined and the other side 66 wholly inclined and extended downwardly to horizontal reciprocating plates 70 to effect the discharge of material. Pivoted levers 68 mounted on the troughs and each having one arm 72 engaging with a slot in the plate 70 while the other arm extends through the plate 66 into the discharge passage to assist the discharge. Specification 587,239 is referred to.
