Claims (9)

1. Способ производства цементного клинкера с использованием протяженной цементной печи, имеющей загрузочный конец и нагревательный конец, причем нагревательный конец наклонен вниз относительно загрузочного конца, а способ содержит следующие операции
подачи тепла от источника тепла к указанному нагревательному концу печи,
подачи потока шихтового материала, содержащего известняк, в указанный загрузочный конец печи, так что поток шихтового материала движется по направлению к указанному теплу в нагревательном конце печи,
дробления и грохочения воздухоохлаждаемого доменного шлака с целью получения частиц преимущественно диаметром до 51 мм, и
добавления определенного количества указанного дробленого и грохоченого доменного шлака к указанному потоку шихтового материала в указанном загрузочном конце печи таким образом, что по мере движения шихтового материала и доменного шлака по направлению к указанному нагревательному концу печи доменный шлак плавится под воздействием указанного тепла и диффундирует в шихтовой материал, образуя цементный клинкер.1. A method of manufacturing a cement clinker using an extended cement kiln having a loading end and a heating end, the heating end inclined downward relative to the loading end, and the method comprises the following operations
heat supply from the heat source to the specified heating end of the furnace,
supplying a stream of charge material containing limestone to the specified loading end of the furnace, so that the stream of charge material moves towards the specified heat in the heating end of the furnace,
crushing and screening of air-cooled blast furnace slag in order to obtain particles mainly with a diameter of up to 51 mm, and
adding a certain amount of the specified crushed and screened blast furnace slag to the specified flow of charge material in the specified loading end of the furnace so that as the charge material and blast furnace slag move towards the specified heating end of the furnace, the blast furnace slag melts under the influence of the specified heat and diffuses into the charge material forming a cement clinker. 2. Способ по п. 1, отличающийся тем, что доменный шлак добавляют в загрузочный конец печи раздельно с шихтовым материалом. 2. The method according to p. 1, characterized in that the blast furnace slag is added to the loading end of the furnace separately from the charge material. 3. Способ по п. 1, отличающийся тем, что доменный шлак и шихтовой материал смешивают перед тем, как подать в загрузочный конец печи. 3. The method according to p. 1, characterized in that the blast furnace slag and charge material are mixed before being fed to the loading end of the furnace. 4.

Устройство по п. 7, отличающееся тем, что конвейерные средства содержат первое конвейерное средство для подачи в загрузочный конец указанной вращающейся печи потока шихтового материала, и второе конвейерное средство для подачи в загрузочный конец вращающейся печи доменного шлака отдельно от шихтового материала. 8. The device according to p. 7, characterized in that the conveyor means comprise first conveyor means for supplying a charge stream of material to the loading end of said rotary kiln, and second conveyor means for supplying blast furnace slag to the loading end of the rotary kiln separately from the charge material. 9. Устройство по п. 7, отличающееся тем, что оно содержит регулятор, соединенный с первым вторым конвейерным средством и предназначенный для регулирования доли доменного шлака относительно шихтового материала, поступающего во вращающуюся печь с целью получения цементного клинкера, имеющего заданный химический состав. 9. The device according to p. 7, characterized in that it contains a regulator connected to the first second conveyor means and designed to regulate the proportion of blast furnace slag relative to the charge material entering the rotary kiln in order to obtain a cement clinker having a given chemical composition.
