Abstract

The invention relates to the technical field of preparation processes of aluminate cement, in particular to a processing method of an aluminate cement added admixture. The method includes the steps of: 1, crushing bauxite and limestone by a crusher respectively to obtain a bauxite material and a limestone material with a particle size of not more than 20mm; 2, mixing the bauxite material and the limestone material according to a ratio of 53%:47% to obtain a mixture; 3, grinding the mixture by a raw material ball mill, and sieving the ground mixture to obtain a powdery raw material; 4, conducting homogenizing; 5, balling the homogenized raw material, and calcining the balled raw material in a rotary kiln to obtain a clinker; and step 6, cooling the obtained clinker, then adding bauxite clinker in proportion, mixing the substances uniformly, and performing grinding by a ball mill to obtain the finished aluminate cement; and 7, conducting inspection, packaging, warehousing and sampling inspection, and then carrying out mechanical quantitative packaging and warehousing.

Description

technical field [0001] The invention relates to the technical field of preparation technology of aluminate cement, in particular to a processing method for adding admixture to aluminate cement. Background technique [0002] Aluminate cement is a hydraulic cementitious material made of bauxite and limestone as raw materials, calcined clinker with calcium aluminate as the main component and an alumina content of about 50%, and then ground. Aluminate cement is often brown or brown, and some are gray. The main mineral of aluminate cement is monocalcium aluminate (CaO·Al 2 o 3 , abbreviated CA) and other aluminates, and a small amount of dicalcium silicate (2CaO·SiO 2 ), etc., the colors are mostly gray and white. [0003] However, as there are more and more manufacturers of calcium aluminate series products nationwide, and the bauxite resources are limited, the raw material bauxite is also less and less, resulting in high production costs, making it difficult for manufacture...
