Silicon fine powder special airflow pulverization is to use supersonic airflow to mushing the material and materials with a small collision, the equipment is worn, and the product is free of iron contamination. A ceramic liner can be used to ensure high purity of silicon fine powder for high purity stone micropowder. No water separation, water is washed, complete dry production, and the production is better than the particle size distribution of silicon powder. The fineness of the finished product reached D97 = 3-74 μm, and the purity reached 99.5%. Stable, complete hierarchical flow field and special sealing measures, reliably prevent leakage of crude particles, narrow particle size distribution and no large particles. There is a plastic function on the particle shape. Variable Combination Structure: One-purpose dual use, which can be pulverized, and can be graded separately. Quartz Mo-hardness is 7, so the wear-resistant treatment is wear-resistant, and the inner abrasion resistant material is greatly reduced, and the losses of the equipment are greatly reduced, and the service life is extended. The whole process uses a negative pressure method, and there is no dust pollution on site, and the production environment is excellent. The equipment is balanced, the vibration is small, low noise. High automation control is high, the equipment is stable, and can be turned on continuously.
The two steps of pulverization grading are generally at the end of the powder processing process, so the performance of the final finished product has a great effect. For example, in the battery material, it is an important part. If the product is unqualified or high, the yield will be greatly reduced, and this loss is unpredictable for battery materials whose original price is high. Therefore, the battery material produced by the airflow pulverizer can achieve a qualified granularity, and it is especially important to crush and large particles. Many users will ask if the airflow pulverizer can reach the nano-stage, and the following small series will answer this question.
The airflow pulverizer is an ultrafine pulverized apparatus, not a nano-pulverized apparatus, 200 nm or less to be called nanometers, and the physical method is difficult to reach nano-level. The performance parameters are D97, 2-45UM, that is, the fineness can be achieved 97%, 2um or so, if it is 50% or average particle size, at about 0.5-1 um, such performance is the limit of the device, but also for some comparison Special materials, not all materials can reach this requirement, so the gas current pulverizer is not reached.
The initial fineness of the raw material is related to the physical properties of materials.The fluidity in the material is related to the uniformity of particles. 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. It 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. There is a relationship with the feed speed, not all material fluidity is very good, whether it is a screw feeding or a vibration feed, the feed process is a very important factor, some of which is very fine, this It is necessary to reach the feed effect with a dedicated personalized configuration. Therefore, for some kind of material ZUI's good way is to do a test to see the effect, don't take any fineness of some kind of machine, the same machine is smashed, other materials may reach D100
or more Edited whether the airflow crusher can reach nano-level, after understanding, I believe that everyone has a new understanding. Airflow pulverizer is widely used in chemical, minerals, metallurgy, abrasives, ceramics, refractory, pharmaceutical, pesticides, food, health products, new materials, etc. Party ~ < 2 microns, but for another material, it may be D90 < 5 microns.
For AlPa Powder Technology, the so-called innovation not only refers to the newness of powder equipment technology and products, but more precisely, innovation is a kind of thinking, whether it is product innovation, or Enterprise system, marketing method innovation, has maintained sustainable development vitality for ALPA powder technology, and also the road to industrial powder equipment industry.
