Cement production method by adding naphthalene sulfonate water reducer

Abstract

The invention discloses a cement production method by adding naphthalene sulfonate water reducer, 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: 12 parts of triethanolamine, 52 parts of diethylene glycol, 12 parts of sodium tripolyphosphate, 106 parts of xylitol, 11 parts of sodium thiosulfate, 6 parts of naphthalene sulfonate water reducer, 65 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 a naphthalenesulfonate water reducer. 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, in view of the above problems, propose a kind of cement production method that adds naphthalene sulfonate superplasticizer, to realize the advantag...
