A batching method for improving the flammability of cement raw meal

Abstract

The invention discloses a material preparing method capable of increasing the burnability of a cement raw material. The method includes: detecting the silicon dioxide content of different-source silicon raw materials, and classifying the silicon raw materials with the silicon dioxide content being above 80% as the high-silicon raw materials, and classifying the silicon raw materials with the silicon dioxide content being 40-60% as the low-silicon raw materials; preparing the cement raw material according to three designed ratio values, wherein the silicon raw materials are mixed by the high-silicon raw materials and the low-silicon raw materials in a coordinated manner, the doping quantity of the high-silicon raw materials and the low-silicon raw materials is determined through a raw material burnability experiment, and the doping quantity of the low-silicon raw materials accounts for 7.91-10.83% of the total mass of the cement raw material. The novel material preparing method has theadvantages that the problem of burnability instability caused by the fact the cement raw material is prepared by using different silicon raw materials during cement production is solved, the range ofthe silicon raw materials capable of being used by cement production is expanded, and the raw material purchasing cost of the cement production can be lowered effectively.

Description

technical field [0001] The invention belongs to the field of cement clinker production, in particular to a batching method for improving the burnability of cement raw meal, and is especially suitable for raw meal batching in cement production. Background technique [0002] The cement industry is a high consumption and high energy consumption industry. At the same time, the production of cement industry is relatively simple, which determines that it is a low value-added product and has no obvious price advantage in the market. At present, my country's cement industry has a serious overcapacity, the competition in the cement industry is becoming increasingly fierce, the cement market price continues to fall, and the profits of various cement companies have fallen sharply. The survival and development of cement companies are facing severe challenges. [0003] If cement enterprises want to survive and develop, they must strive to improve their efficiency, and the most direct an...
