Document Type and Number:
Japanese Patent JPS6053267
Kind Code:
B2
Abstract:
Disclosed is an apparatus for calcining raw materials in the form of powder or particles. The gases entrain the particles to spiral upward in the calcining furnace. In an upper throttle chamber the relatively coarse particles which have not been completely calcined are separated from the gas flow and returned into the calcining zone to be calcined again. This pattern of material flow is repeated several times. The calcining efficiency can be improved, so that the furnace can be made small in size. The uniformly calcined particles are discharged from the top of the furnace and introduced into one or more cyclone separators through an outlet duct including a 180 DEG bend section.
