Abstract

The invention provides a slag powder grinding aid for reducing water consumption. The slag powder grinding aid for reducing water consumption is prepared from the following components in parts by weight: 20-22 parts of water, 6-8 parts of industrial salt, 4-5 parts of sodium thiosulfate, 5-7 parts of sodium thiosulfate, 3-5 parts of urea, 25-35 parts of compound sodium thiosulfate, 20-24 parts ofglycerinum and 4-6 parts of sugar. The slag powder grinding aid for reducing water consumption can be used for reducing the use level of water, protects the environment and saves resources.

Description

technical field [0001] The invention relates to the technical field of mineral powder grinding, in particular to a steel slag powder grinding aid for reducing water consumption and a preparation method thereof. Background technique [0002] Steel slag is a composite solid solution formed during the smelting process due to the addition of slagging materials such as lime and fluorite, the corrosion of the furnace lining, and the oxidation of silicon and iron in molten iron. The amount is generally 15% to 20% of steel production. At present, there are more than 100 million tons of steel slag stored in our country, and the utilization rate is about 10%. The stacking of steel slag in the slag yard not only occupies land, but also weathers into alkaline dust, pollutes and destroys the surrounding environment, and brings great harm to the sustainable development of the national economy. Come the huge pressure and burden. The chemical composition of steel slag is similar to that of...
