Preparation method of cement raw meal grinding activator

Abstract

The invention discloses a preparation method of a cement raw meal grinding activator. The method comprises the steps of: (1) taking any one of diethanol amine, sulfite yeast distiller's wort, and sodium adipate as an isomer composite, or taking any two or three of diethanol amine, sulfite yeast distiller's wort, and sodium adipate for mixing so as to obtain an isomer composite mixed solution, with the mass percent of each component of the obtained isomer composite mixed solution not less than 10%; (2) conducting magnetizing treatment to the isomer composite mixed solution obtained in step (1)in a magnetic field of B=0.40-1.20 Tesla, thus obtaining the cement raw meal grinding activator. Application of the obtained activator of the invention in cement raw meal grinding can effectively reduce raw material surface energy, improve grinding efficiency, lower energy consumption during grinding, enhance raw meal specific surface area, lower raw meal calcination temperature and coal consumption, thus being in favor of the sustainable development of cement industry.

Description

technical field [0001] The invention belongs to the technical field of building material cement clinker production additives and high-efficiency comprehensive utilization of resources, and more specifically relates to a preparation method of an activator for cement raw meal grinding. Background technique [0002] Grinding is the process of turning granular materials into fine powder through the action of mechanical force. For the cement raw meal grinding process, it is also a process of uniform mixing of several raw material fine powders. The purpose of grinding is to increase the surface area of ​​the material, increase the physical and chemical activity of the raw meal, and promote the rapid completion of its physical and chemical reactions during the calcination process of the raw meal. [0003] The fineness of the raw meal directly affects the formation rate of minerals in the clinker during calcination in the kiln. The finer the fineness of the raw meal, the more unif...

Problems solved by technology

The finer the fineness of the raw meal, the more uniform the components of the raw meal can be mixed, and the more fully the components of the raw meal can be in contact with each other during calcination in the kiln, so that the speed of calcium carbonate decomposition reaction, solid phase reaction and solid-liquid phase reaction Acceleration is beneficial to the absorption of free calcium oxide to generate tricalcium silicate which plays the main role in gelling efficiency; but when the raw meal fineness is too fine, the power consumption per unit product of grinding will increase significantly, and the output of the mill will decrease rapidly, while the clinker The absorption of free calcium oxide in the
