PROCESS OF PRODUCTION OF CEMENT CLINKER Russian patent published in 1995 - IPC

FIELD: construction industry. SUBSTANCE: process of production of cement clinker involves grinding of raw components, preparation of two mixtures (one being clinker fuel-containing), granulation, feed to conveyer grid first clinker fuel-containing mixture granules, then sinter mixture granules, size 10.0-15.0 mm with content of solid fuel between 4 and 6%. Height of layer of sinter mixture is 50-100 mm whereas height of two layers amounts to 360-400 mm. This process is followed by annealing. Laying of granules of sinter mixture in upper low-temperature layer and granules of clinker mixture in lower high-temperature layer provides for temperature in layer of clinker mixture necessary for formation of clinker which excludes necessity of return of clinker for new annealing and provides for 2.0-2.5-fold increase of specific output of finished product and for enhanced efficiency of process. Losses of heat diminish in this case by 5-10 %. EFFECT: increased output of finished product, diminished heat losses. 3 tbl
