The airflow pulverizer enables the shape of the ultrafine powder to maintain the shape of the origin
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.
There are two basic methods for obtaining ultrafine fine powder, one is a physical method. Second, the primary equipment for chemical synthesis, physical methods, super fine powder, is a variety of pulverizer, classification machine and collection equipment such as airflow pulverizer, vibration grinding, Raymond mill, ball mill and so on. In these devices, the airflow pulverizer is the primary approach to prepare ultrafine powder for dry methods.
The airflow pulverizer is to form a high-speed air flow using a plurality of relative-arranged nozzles, and then use high-speed airflow to accelerate the material to the treble speed to collide with each other at the intersection of the nozzle. the goal of. The crushed material enters the grading chamber with the rising airflow. Since the grading rotor is high-speed rotation, the particles are subjected to the centrifugal force generated by the hierarchical rotor, and the center of heart is generated by the viscous action of the airflow. When the particles are larger than the heart force, the coarse particles above the fractional diameter The return chamber continues to impact, the fine particles flow into the cyclone separator, the trap is collected, and the gas is discharged from the air blower.
The preparation of ultrafine powder was performed on more than a dozen materials using the MQW airflow pulverizer, and the particle shape of these ultrafine powder was observed and analyzed by electronic scanning electron microscope. The shape of the graded particles can be given to the inherent genus of the powder.Sex.
MQW fluidized bed airflow pulverizer is a traditional fluidized bed airflow pulverizer, an updated product for spray airflow pulverizer, horizontal airflow pulverizer and other types of airflow pulverizer, and equipment mainly consolidated host, high Hierarchical turbine classifier, cyclone collector, bag dust collector, air compressor, etc.
If the product has a quality problem, it is implemented, the replacement, and retreats "three-package terms". From the date of warranty of the equipment, customers have the whole machine with invoice and warranty vouchers. Free warranty "warranty service" for one year. In the normal use of equipment, the cost of maintenance produced by the unit itself is subjected to the ALPA, except for the except of the ALPA.
