Embodiment 1

[0034] The specific operation of using phosphorus slag to produce high-quality and high-volume phosphorus slag cement is as follows:

[0035] The incoming raw materials should be as stable as possible, and the main raw materials should be made from a single ore as much as possible. Shale, phosphorus slag, sandstone, limestone, and iron ore should be used as five-component ingredients, and sandstone should be used as siliceous correction material to adjust SiO in the raw meal. 2 . Make a batching plan according to the chemical composition of each raw material, put it into the raw material mill for grinding according to the ratio of the batching plan, and finally mix. Wherein the chemical composition of the raw material in implementation is shown in Table 1:

Abstract

The invention relates to the field of cement production, in particular to high-quality and high-volume phosphorous slag cement produced through phosphorus slag and a production method of the cement. The production method specifically comprises the following steps that shale, the phosphorous slag, sandstone, limestone and iron ores are used as ingredients, the sandstone serves as a siliceous calibration raw material to be ground to obtain a raw material, the raw material is preheated, decomposed, calcined at high temperature and then cooled to obtain phosphorus slag cement clinker, gypsum, the limestone, the phosphorus slag and the like are ground separately to be mixed with the phosphorus slag cement clinker, and then the phosphorus slag cement is prepared. According to the method, the firing temperature can be lowered in the clinker calcination process, therefore, a liquid phase is generated in advance, the clinker yield is increased, CO2 emission is reduced, and energy conversation and emission reduction are achieved.

Description

technical field [0001] The invention relates to the field of cement production, in particular to a method for producing high-quality and high-volume phosphorus slag cement by using phosphorus slag. Background technique [0002] Phosphorus slag is a kind of industrial waste. Long-term stacking not only wastes a lot of land resources, but also seriously pollutes the surrounding air and soil under the action of wind and rain. With the country's emphasis on environmental protection, more and more companies are beginning to seek efficient utilization of phosphorus slag. Cement plants generally use raw materials such as limestone and shale to calcinate clinker. It not only wastes a lot of natural resources, but also consumes a lot of energy for calcination, and the production cost is relatively high. [0003] Phosphorus slag is an industrial by-product produced during the production of yellow phosphorus, and its main components are CaO and SiO 2 . Contents of the invention ...
