Technical background of high density silicon carbide sand and fine powder:
In powder engineering, mechanical grinding is mainly used for powder crushing, and the grinding force used for powder shaping should not be too strong, otherwise the powder particles will be broken, leading to the failure of particle shaping.By adjusting the grinding process parameters, the SiC powder particles are rubbed in the mill, and the irregular part of the particles is ground off.
According to the analysis of the above figure, it can be seen that the crushing effect on the powder particles is basically in the form of dropping and throwing. Therefore, using this method to shape the particles, the crushing effect of the equipment on the material particles should be minimized, and the grinding effect between the grinding medium and the silicon carbide powder particles should be increased, so as to realize the shaping of the silicon carbide powder particles.
The results show that the powder shaping by mechanical grinding process is affected by the following process parameters: the speed of mill, the filling of grinding medium, the ratio of grinding medium and material, the size of grinding medium, the solid content of slurry and grinding time.In the whole process, by adjusting various process parameters, on the one hand, the powder particles are not broken, on the other hand, the irregular parts of SiC powder particles are slowly ground off by grinding.
