Title:
HEAT TREATMENT DEVICE FOR FINE PARTICLE MATERIAL
Document Type and Number:
Japanese Patent JPS59137350
Kind Code:
A
Abstract:
Apparatus for heat treating fine-grained material comprises a rotary kiln into which material is delivered from a multistage preheater that communicates with the kiln via a vertical exhaust gas duct. Treated material is discharged from the kiln to a cooler from which two cooling air ducts extend and communicate with the exhaust gas duct at two vertically spaced zones. Material from the second lowest preheater stage is introduced into the exhaust gas duct adjacent the lower cooling air duct. Fuel is introduced into the exhaust gas duct adjacent each of the cooling air ducts. The apparatus is distinguished by a particularly high degree of deacidification of the raw material and good combustion of the fuel.
