Problems solved by technology

All there are some defects in the formula composition of these liquid grinding aids: due to the increasing shortage of world oil resources, the prices of the main raw material triethanolamine and organosilicon polymer (certain siloxane) of grinding aids are also constantly rising, seeking A relatively low-cost and effective slag grinding aid product is an urgent problem to be solved in the domestic grinding aid industry, and slag micropowder production enterprises require that the output of the mill be increased by more than 14% in order to further reduce electricity consumption. consumption, save energy

Abstract

The invention relates to the technical field of mineral grinding, in particular to a slag grinding aid. The slag grinding aid is prepared from, by weight, 25-40 parts of isopropanolamine, 10-20 parts of butyl acetate, 8-18 parts of ethylene glycol monobutyl ether, 8-15 parts of bamboo vinegar, 2-7 parts of cellulose ether, 1-5 parts of carrageenan and 33-43 parts of deionized water. According to the slag grinding aid, the grindability of mineral powder and the activity index of superfine slag powder can be improved, the yield of a grinding machine can be increased, the power consumption per unit time is reduced, and the storage period can be also prolonged.

Description

technical field [0001] The invention relates to the technical field of mineral grinding, in particular to a slag grinding aid. Background technique [0002] Slag is a granular active material formed from the molten material mainly composed of calcium silicate and calcium aluminate discharged during ironmaking, which is quenched by water and quenched. It generally contains 80-90% glass phase, and its main mineral is dicalcium silicate (C 2 S), calcium aluminate feldspar (C 2 AS), magnesian feldspar (C 2 MS 2 ), anorthite (CAS 2 )Wait. The chemical composition of slag is generally CaO 3 5~45%, SiO 2 25-40%, Al 2 o 3 6-15%, FeO0.5-1%. Quality coefficient of slag (CaO+MgO+Al 2 o 3 ) / (SiO 2 +MnO+TiO 2 ) is larger, the activity of slag is higher, that is, CaO, Al 2 o 3 High content, SiO 2 Slag with low content has high activity. It is a "low calcium and high silicon" clinker with excellent "potential hydraulic hardness". The national standard GB / T203 stipulates ...
