Embodiment Construction

[0013] A method for producing cement by adding lignosulfonate, comprising: crushing raw materials for cement production to form coarse particle materials; using a classifier to grind the coarse particle materials into fine powder through grinding equipment, and then using dust collection equipment to collect It is the raw meal powder; after the raw meal powder is further mixed evenly, it is preheated and decomposed and sent to the cement kiln to produce clinker; the above-mentioned cement grinding aid is added when grinding through the grinding equipment; the cement grinding aid, in parts by weight The proportion is as follows: 15 parts of triethanolamine; 60 parts of diethylene glycol; 20 parts of sodium tripolyphosphate; 104 parts of xylitol; 18 parts of sodium thiosulfate; 11 parts of lignosulfonate; 45 parts of water.

[0014] The components of the cement grinding aid mentioned above are mixed and then subjected to magnetization treatment.

Abstract

The invention discloses a cement production method by adding lignosulfonate, which includes the following steps of breaking raw materials for cement production to form coarse materials; grinding the coarse materials into fine powder through a grinding machine by a powder concentrator, and then collecting the powder by utilizing a dust collector to be used as raw material powder; after further mixing the raw material powder uniformly, conveying the raw material powder to a cement kiln to generate clinker after being preheated to decompose. Cement grinding aid is added during the grinding by the grinding machine; the cement grinding aid includes the following components in parts by weight: 15 parts of triethanolamine, 60 parts of diethylene glycol, 20 parts of sodium tripolyphosphate, 104 parts of xylitol, 18 parts of sodium thiosulfate, 11 parts of lignosulfonate, 45 parts of water. The advantage of abundant grinding of cement raw materials is realized.

Description

technical field [0001] The invention relates to the field of cement production, in particular to a cement production method adding lignosulfonate. Background technique [0002] At present, my country is a big country in the production and use of cement, and cement is a high-energy-consuming and high-pollution industry. The raw materials of cement are mostly bulk materials such as limestone, iron ore, clay, and coal. During production, bulk raw materials need to be processed. Crushing treatment, so as to reduce the heat consumption of cement in cement kiln. However, in the crushing process of raw materials, if the grinding equipment is directly used for grinding, it will cause the problem of insufficient grinding of raw materials. Contents of the invention [0003] The object of the present invention is to propose a cement production method adding lignosulfonate to achieve the advantages of sufficient grinding of cement raw materials in view of the above problems. [0004]...
