Triethanolamine (TEA; C6H15NO3) is an alkanolamine that is frequently used as a main chemical working component in industrial manufacturing plants (Speranza et al. 2006). Its chemical properties makes it a popular cutting and metal working fluid as well as corrosion inhibitor (Weavers et al. 1997).
This article presents the evaluation of three types of grinding intensifier additives which were used for the production of LC3 cement, as well as the addition of LC2 minerals, treated in a laboratory scale ball mill. For …
In fine grinding of cement in a ball mill, it is sometimes impractical to grind finer in a dry state. Even though the chemical reactivity requires the material to be dry ground, it is sometimes necessary to use different breakage machines to obtain the product, but it is usually more expensive, requires more energy and reduces capacity.
Triethanolamine is a controversial ingredient used in cosmetics as a pH balancer and emulsion stabilizer. Learn more at Paula's Choice.
Effectiveness of Triethanolamine on Grindability and Properties of Portland Cement in Laboratory Ball and Vibrating Disk Mills
A molecular modified PCE-type GA was self-synthesized, and the grindability concerning grinding duration and particle size distribution of ground cement was evaluated. Setting time, flowability, hydration heat, mechanical properties and microstructure of the ground cement were also investigated. The results show that: PCE-type GA is effective …
High temperature of the ball mill will affact the efficiency 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% -10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded Reasons
