ultra fine grinding mill grinding effect

The principle of ultra fine grinding mill and fine grading mainly includes the particle size, grain property and characterization method of ultrafine powder, the deformation and crushing mechanism of the fine particles, the kinetics and mathematical model of the crushing process, The material is not in the crushing method, equipment and not to the crushing conditions and crushing environment energy consumption law, crushing efficiency and energy utilization, not to the mechanical stress of the way and equipment in the case of grinding to the crushed material crystal Structural and physical and chemical properties (ie mechanics of the pulverization process), grinding aids, dispersants and the like, and the effects of the physical and chemical environment on the product’s sewing, physical and chemical properties, crushing efficiency and capacity utilization.
Ultrafine powder particle size, particle size characteristics and characterization methods, crushing process of the mechanical principle and the general powder has many and to the place.
The ultrafine pulverization process is not only a process of particle size reduction, but also when the material is pulverized by mechanical force, accompanied by the change in the grain structure and the physical and chemical properties of the material to be pulverized. This change is negligible for the relatively coarse pulverization process, but for the ultrafine pulverization process, the pulverization time is long, the crushing strength is large and the particle size of the material is pulverized to micron or less Under certain crushing processes and conditions. This change in the crystal structure and physicochemical properties of the pulverized material caused by the mechanical superfine pulverization is called the mechanical or mechanical chemical effect of the pulverization process. This mechanical and chemical effect on the performance of the material to be crushed to a certain extent, is purposefully applied to the powder material surface activation treatment.
The mechanical and chemical changes in the pulverization process include:
Activated by the rearrangement of the atomic structure of the material and heavy fiber crystal, the surface layer of spontaneous reorganization, the formation of non-quality structure.
The foreign molecules (gases, vapors, surface active parts, etc.) spontaneously carry out physical adsorption and chemical adsorption on the newly generated surface.
The chemical composition of the material being pulverized, and the interaction between the particles and the chemical reaction.
The physical properties of the material to be pulverized.
These changes are not in all the crushing operations are expected to exist, it is with the mechanical force of the way, crushing time, crushing environment and the type of material to be crushed, grain, materialized but qualitative and so on. Studies have shown that only the ultra-fine grinding or ultra-fine grinding process, the above mechanical chemical phenomenon will be significant or detected. This is the ultra-fine grinding is the unit smash the product can be a high operation, the mechanical force of the role of strength, material research time is long, the material surface area is large, the surface is high. In this regard, the following discussion of the process of ultra-crushing process of chemical phenomenon.
In the process of ultra fine grinding mill, due to the strong and lasting mechanical force, the powder material does not occur to the extent of character distortion, grain size becomes smaller, the structure of disorder, the surface of the formation of amorphous or amorphous substances, Polycrystalline conversion occurs. These changes can be detected by x-ray diffraction, infrared spectroscopy, nuclear magnetic resonance, electron paramagnetic resonance, and differential thermal apparatus.
The reactivity of the calcium hydroxide material can be enhanced by fine grinding, which is very important in the construction of the building materials. There is not enough inertia or activity to these materials for hydration. In the process of ultra fine grinding mill, when the particle size is reduced to micron level, the particles of the placard tends to be uniform, the defect is reduced, the strength and the hardness increase, the grinding difficulty is greatly increased. The ratio of surface area and surface energy increased significantly, and the tendency of the fine particles to agglomerate (to form secondary or tertiary particles) was significantly enhanced. For the wet pulverization, the lice degree of the ore was significantly increased. The mobility of the oars is significantly worse. If you do not take a certain process measures, then the crushing efficiency will be significantly reduced, the energy consumption per unit of product will be significantly improved, which is in the process of mixing crushing material must be good dispersion and in some cases the use of dispersants or grinding The background of the agent.
Abrasive is a class of chemicals that can significantly improve the efficiency of ultra fine grinding mill operations or reduce the energy consumption per unit of product. It includes organic and inorganic substances that do not state (solid, liquid and gaseous). The main purpose of adding a grinding aid is to improve the grinding of the material, to prevent the melting of micro-particles, agglomeration and adhesion in the mill liner and grinding media to improve the flow of material within the mill, thereby enhancing the product Fineness and sewing products to reduce the crushing limit and energy consumption per unit of product. Obviously, the dispersant is also a grinding aid, it is by preventing the agglomeration of particles, reducing the oars to play the role of grinding.
