Title:
PROCESS AND DEVICE FOR HEAT TREATING PRELIMINARY HEATED AND WELL CALCINED FINE GRAIN MATERIAL
Document Type and Number:
Japanese Patent JPS5988347
Kind Code:
A
Abstract:
A method and apparatus for burning fine grained products, such as in the manufacture of cement clinker from raw cement meal wherein preheated, calcined meal is heated in a separate heating assembly to a temperature from approximately 900 DEG C. to approximately 1250 DEG C. and is then sintered into clinker in a burning assembly such as a rotary tubular kiln. The present invention provides a means for achieving a fast and uniform continuous heating in the heating assembly without reaching the critical temperature of melt phase formation and without danger of encrustations, the heat required for rapid heating being released in controlled amounts in the heating assembly, where it is immediately absorbed by the product, the heat being provided by a plurality of points of fuel introduction and/or combustion air introduction distributed over the heating assembly.
