Title:
METHOD AND APPARATUS FOR BURNING GRANULAR SUBSTANCE*ESPECIALLY FOR MANUFACTURING CEMENT CLINKER
Document Type and Number:
Japanese Patent JPS5547253
Kind Code:
A
Abstract:
The invention relates to a method for burning fine-grain material, particularly for the manufacture of cement clinker from cement raw meal. The material is thermally treated in a multistage burning process with a pre-heating stage, a calcining stage with a high-degree of calcination, a sintering stage in a very short rotary kiln and a cooling stage. Fuel is introduced both into the sintering stage in the short rotary kiln as well as into the calcinating stage. Hot exhaust air from the cooling stage is supplied both to the sintering stage as well as to the calcining stage as furnace air. The invention also relates to an apparatus for the manufacture of mineral products of the burning process such as cement clinker.
