A special grinding aid for vertical grinding of cement and its application |
| abstract |
The invention discloses a special grinding aid for vertical grinding of cement and its application. The grinding aid comprises the following raw materials by weight: 5-40% of water-soluble polyester; 5-20% of inorganic dispersion enhancer; Alcohol or alcohol amine 5-20%; water 40-70%; in the formula of the special grinding aid for vertical grinding cement provided by the present invention, the high viscosity of the water-soluble polyester can inhibit the grinding aid from grinding during the grinding process. The dispersing effect of the cement is to stabilize the material layer, so that the material can be fully milled by the grinding roller on the grinding disc. With the progress of cement grinding, the water-soluble polyester is hydrolyzed under the high temperature and alkaline environment and the grinding pressure of the grinding roller. Or cracked into polyols, and/or alcoholamines and polyacids and low molecular weight water-soluble polyester polymers, which are combined with polyols, and/or alcoholamines and inorganic dispersion enhancers in the formulation of grinding aids to improve grinding The dispersibility of the final fine powder is improved, and the powder selection efficiency is improved. |
