isopropanolamine, ethylene glycol, glycerol and sorbitol as grinding components, Study of 5 kinds of grinding components, Grinding dosage control components from % to % ( according to the quality of cement, similarly here in after), The result is shown below.
The invention relates to a preparation method of a cement grinding aid, and the preparation method comprises the following steps: mixing triisopropanolamine with water in the mass ratio of 1:3 to 1:5, heating to 40 to 50 DEG C, until the triisopropanolamine is completely dissolved, to obtain an A solution; adding silica fume to dodecylbenzene, stirring to fully dissolve to obtain a B
Ethylene glycol as grinding aid in cement mobiliclassicirinding aid diethyl gylcol for cement millhe liquid cement grinding aid comprises the components with the weight 3 to 5 percent of diethylene glycol, 2 to 5 percent of sodium formate, manufacture of cement grinding aids cement mill grinding efficiency, low strength cement.
Triethylene glycol. Tri ethylene glycol is prepared commercially as a coproduct of the oxidation of ethylene at high temperature, in the presence of a silver oxide catalyst. The ethylene oxide is then hydrated to yield mono, di, tri, and tetra ethylene glycols. he main uses for tri ethylene glycol are based upon its hygroscopic quality.
Grinding aids (GAs) have been an important advent in the comminution circuits. Over thelast few decades, in order to address the high energy consumption and scarcity of potablewater for mineral

The grindingaids effect of moisture, triethanolamine (TEA) and ethylene glycol (EG) on grinding performance and product quality of calcite Abstract In this study, the effects of liquid additives such as water, triethanolamine (TEA) and ethylene glycol (EG) on the dry fine grinding of calcite were investigated by using a laboratory scale vertical stirred mill.
#0183;#32;Results of the grinding aid tests, including comparisons with ethylene glycol (a known grinding aid) appear in Table 1. As is shown by the above example, a grinding aid according to the present invention, when added to a Portland cement clinker, increases grinding efficiency over the clinker alone (quot;blankquot;) as well as a known, chemically similar grinding aid (ethylene glycol).
Ethylene glycol (IUPAC name: ethane1,2diol) is an organic compound with the formula (CH 2 OH) 2. It is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations. It is an odorless, colorless, sweettasting, viscous liquid.

#0183;#32;When ethylene glycol (EG) is solidified with cement, the EG appears to occupy at least 3 different kinds of sites, characterized by differing extractability. Gross alterations of the morphology of the cement matrix do not become apparent until rather large amounts of EG (EG/cement = by weight) have been added to the hydrating cement mixture.
Ethylene Glycol based water solutions are common in heattransfer applications where the temperature in the heat transfer fluid can be below 32 o F (0 o C).Ethylene glycol is also commonly used in heating applications that temporarily may not be operated (cold) in surroundings with freezing conditions such as cars and machines with water cooled engines.
In this study, the effects of liquid additives such as water, triethanolamine (TEA) and ethylene glycol (EG) on the dry fine grinding of calcite were investigated by using a laboratory scale vertical stirred mill. The experiments were carried out
