According to the physical properties of the battery powder, the physical properties of the negative electrode material, using different devices to perform pulverization grading to achieve the optimum output ratio. According to the large number of successful cases of many companies and battery powders, I use our battery powder special mechanical ultrafine pulverizer - graded impact grinding (effectively reducing the use of production equipment) to achieve the effect of pulverization; for lithium batteries, The nickel-hydrogen battery specific material can be pulverized by fluidized bed. High purity requirements, anti-oxidation can be used with inert gas protection pulverization charters, isolated oxygen sealing production.The pulverization of electrode material can be used with a lot of pulverization equipment, such as a grinder, a bar pin sand mill, a gas flow pulverizer, and the like. Compared with other pulverized devices, the average particle size after processing the gas flow pulverizer is narrow, the particle size distribution is narrow, the particle surface is smooth, the particle shape is standardized, the purity is high, the activity is high, the dispersibility is good, and the preparation requirements of the electrode material are complete. It is therefore widely used.
The airflow pulverizer utilizes the kinetic energy of the high-speed airflow to collide with each other and rubbed. It has the characteristics of continuous, high production capacity and high automation. It can be applied in a variety of finely processed industries such as electronic materials, chemical, mining, metal powders. Its maximum shortage is that the energy utilization rate is low, so it should be sought to reduce energy consumption, increase energy utilization, to meet the trend and requirements of building energy-saving and environmentally friendly society. The average particle size of the material after using the airflow crushing, then what extent is therethrough, what extent can the airflow crushing machine? It has a relationship with the following factors:
1, the initial fineness of the raw material, our airflow pulverizer generally requires the feed to 50 mesh or less.
2, related to the physical properties of the material, the fluidity, the uniformity of the particles in the material is related. Some materials are fluidity, high impurities, high solvent content, can be blocked in the production process, this time you need to use special equipment, not all materials can be pulverized with standard equipment can achieve crushing fineness. .
3, which is related to the pulverization pressure during the pulverization process, and some of the equipment feed pressure is greater than the pulverization pressure, and some equipment is larger than the feed pressure, and the particular material needs to be specifically designed.
4. It is related to the speed of the feeding, not all the material fluidity is very good, whether it is a screw feeding or a vibration feedThe feeding process is a very important factor, some of which is very difficult to add, at this time, it is necessary to use a dedicated personalized configuration to achieve the feed effect.
5, then there is a relationship with the optimization of the airflow pulverizer, there are many airflow mill manufacturers, but the same material is different from the fineness of the manufacturers, even the different models of the same manufacturer. There is also a difference in the fineness of the device.
6, there is a relationship with the skilled degree of operator, and some equipment is initiated to take a small pressure operation, and some are the operation of one step.
The above is Xiaobian's small knowledge on the airflow crusher, more information about the airflow pulverizer, can pay attention to the official website of Shandong El Pai, or inquire.
The new era creates new demand. As economic growth is gradually transforming to intensive environmental protection, each industry is facing unlimited opportunities and challenges. Among them, the ALPA powder technology, which is a typical representative of industrial powder equipment manufacturing enterprises, with the new era - environmentally friendly powder equipment, to promote transformation and upgrading of all walks of life, highlighting their own value.
