(54) METHOD FOR GETTING A CEMENT CLINKER

The invention relates to technology for the production of cement clinker, in particular to the dry method of production. A known method for producing cement clinker consists in preheating raw meal in a baking heat exchanger system and then burning the clinker in a rotary kiln. The disadvantage of this method is the low degree of heat treatment of dry raw baked heat exchangers and a large amount of dust removed from the kiln. The closest in technical essence and the achieved effect to the invention is a method for producing cement clinker, which includes separate heat treatment of the components of the raw mixture when feeding the lime component to the system of baked heat exchangers, followed by mixing with the clay component in the form of bituminous shale and burning the volatile components of the baking devices 2. A disadvantage of the known method is the relatively low efficiency of baked heat exchangers. caused by a high degree of dust circulation in their hot stage. The purpose of the invention is to intensify shale combustion and improve the performance of baked heat exchangers. The goal is achieved in that the method of producing cement clinker, which includes separate heat treatment of the components of the raw mix when feeding the lime component to the baked heat exchanger system, followed by blending with the clay component in the form of a lime component into the system of baked heat exchangers, followed by blending with the clay component in the form of a lime component into the system of baked heat exchangers, followed by blending with the clay component in the form of a lime component into the system of baked heat exchangers, followed by blending with the clay component in the form of the lime component into the system of baked heat exchangers, followed by blending with the clay component in the form of the lime component into the system of the baked heat exchangers with subsequent heat treatment of the raw mixture when the lime component is fed into the system of baked heat exchangers, followed by blending with the clay component in the form of the lime component into the system of the baked heat exchangers with the subsequent heating of the lime mixture into the system of the blended heat exchangers followed by mixing the raw material when the lime component is fed to the system burning the volatile components of the latter in the baking devices, mixing the oil shale with limestone is carried out in the charging section of the rotary kiln, and the burning of volatile gases in the ducts connecting the stove and the baking heat; MeHEibie devices. The dryness of the invention is as follows. The bituminous shale supplied to the charging part of the furnace together with the lime is heated by waste furnaces and gases with a temperature of 1000–1200 ° C and volatile gases are ignited from its organic part (the fire is burned in gaeoho, behind the edge of the furnace, Gorengs volatiles; Olig to increase the heat content of furnace gases and provide a gas of decompression of lime limestone, raw materials passing through electric heat exchange, Miyeira 1 part 7; the place with solid organic fuel is melted and the nepej Q is liquid n liquid phase on the top of the raw material in the pile; / nB4iff end that nps-i rotate the furnace to ensure contact with the granulation composer of the raw mix This is the way to the cracking of the spinning of the rotary spin from the first step of the process, you can use it to rotate the spinning of the rotary spinning of the first-mix ; n
