Abstract

The invention relates to the field of grinding aids and discloses a mineral powder grinding aid. The mineral powder grinding aid is prepared from the following raw materials in percentage by weight: 15-22% of triethanolamine, 5-15% of sodium stearate, 10-24% of polyacrylamide 5-10% of sodium hexametaphosphate, 5-10% of sodium pyrophosphate, 2-7% of sodium silicate, 1-5% of dihydrate gypsum, 0.5-1.2% of polytetrafluoroethylene and the balance of water. The invention provides the mineral powder grinding aid which is good in grindability and high in activity and aims at solving the problems of poor grindability and low activity of the existing commercial mineral powder grinding aids; after the mineral powder grinding aid is added, the grinding efficiency of the mineral powder is improved, the yield of the mineral powder is increased, the power consumption of grinding aid is reduced and the specific surface area of the mineral powder is increased.

Description

technical field [0001] The invention relates to the technical field of mineral grinding, in particular to a mineral powder grinding aid. Background technique [0002] The main components of mineral powder are CaO, MgO, Al 2 o 3 , MgO, SiO 2 , MnO, Fe 2 o 3 Silicates and aluminates of equal composition. Under the premise of not changing the production process of the original enterprise, the use of grinding aids has the effects of improving quality, increasing output, reducing costs, reducing power consumption, and increasing benefits. This is of great significance to improving the technical level of mineral powder production enterprises, enhancing the market competitiveness of enterprises, and promoting the development of enterprises. Mineral powder grinding aid is a high-tech product with independent intellectual property rights successfully developed according to the needs of mineral powder production. It is a composite powder material produced through physical and ch...
