Abstract

The invention discloses a cement clinker preparation method and system, relates to the related field of cement clinker preparation, and aims to solve the problems of low sintering efficiency and long sintering time caused by overflow or waste of a large amount of heat released in the conventional cement clinker sintering process. One end of the heating rotary kiln is fixedly connected with a second heat rotation pipe, the other end of the second heat rotation pipe is provided with an exhaust fan, the output end of the exhaust fan is provided with a first heat rotation pipe, and the other end of the first heat rotation pipe is provided with a second preheater. A sixth material flowing pipe is installed at the output end of the second preheater, a fourth powder conveying pump is installed at the other end of the sixth material flowing pipe, a seventh material flowing pipe is installed at the output end of the fourth powder conveying pump, and the seventh material flowing pipe is located at the position, close to the feeding position, of the upper end of the heating rotary kiln; and a fifth material runner pipe is mounted at the input end of the second preheater.

Description

technical field [0001] The invention relates to the field related to the preparation of cement clinker, in particular to a method and system for preparing cement clinker. Background technique [0002] Cement clinker is a semi-finished product obtained by using limestone, clay, and iron as the main raw materials, which are prepared into raw meal in an appropriate proportion, burned until part or all of it is melted, and cooled. In the cement industry, the most commonly used Portland cement clinker is mainly composed of calcium oxide, silicon dioxide and a small amount of aluminum oxide and iron oxide. The main mineral composition is tricalcium silicate, dicalcium silicate, tricalcium aluminate and tetracalcium aluminoferrite. In the cement production process, most of the raw materials are crushed, such as limestone, clay, iron ore and coal. [0003] Since cement clinker is made of raw materials in appropriate proportions, burned to a molten state, and finally cooled to obta...
