my country's amlaitstones play an important role in the world market, but the high long diameter is behind other countries than the preparation technology of ultrafinite gray powder. At present, the particle size of the silica graystone product has been described in technology that it has proved that the ultrasonic speed fluidized bed gas flow pulverizer has advantages in the preparation of high long diaps than silica gray powder. Since the silica grahyme powder has a needle structure, the laser particle measurement can not give a long diameter ratio while characterizing the particle size distribution, only a reference for granularity characteristics, and the energy consumption of the airflow pulverizer is very large.
For a long time, the ultrafine powder particles from the fluidized bed vignette were pulverized by the fluidized bed airflow pulverite, and the lack of silica grayp push-like powder ratio The relationship with the equivalent diameter, in order to make a positive effect on the preparation of the high long diameter than ultrafine silicone powder.
Using MQW fluidized bed airflow pulverizer to pulveriate silica gray stone push powder,It can be seen that the average length diameter ratio is increased rapidly with an average equivalent diameter, and the average equivalent diameter is 4.15 microns, and the average diameter ratio increases to a gentle. When the average equivalent diameter reaches 6.64 microns, the average is more than the bending tends to be gentle, and the average equivalent diameter increases. Since the principle of similar flumental bed is utilized during the pulverization process (the supersonic jet flow generated after the expansion acceleration of the pulverized nozzle is accelerated into the inverse spray flow field, the ground material flow is caused under differential pressure. The material produces a fierce collision, friction, shear, and eliminates the material in the pulverized cavity. Shear and friction have a tendency to peel off the particles along the crystallization process parallel to the force direction. Therefore, the appropriate size shear strength and the friction have a friction to peel the crystal beam into a fibrous effect, which facilitates the preparation of a high long diameter than ultrafinite graystones.
The experiment can be obtained: 1, fluidized bed airflow pulverizer to pulveriate silica grain can obtain a relatively good fibrous particle. 2, fluidized bed vignette pulverizer pulverous silica grayite, the average surface of the silica grain particles can reach 17: 1-20: 1, the average equivalent diameter is more than 6 microns, the average length The radial ratio is not large, and the average equivalent diameter increases, and the average oriented diameter is less than 4 microns. The average long diameter is decreased sharply. Considering that the size of the particle size is also a major indicator of the filler, the particle size is controlled at 4-7 microns when pulverized.
