There are high requirements for the production of black silicon carbide powder, which needs several production processes to make the production run stably, the workers are easy to operate, and the powder rate can meet the requirements of the manufacturer.

 

The principle of airflow comminution of black silicon carbide powder is that the particles are crushed by impact, friction and shear between particles or between particles and targets under the action of high-speed airflow

 

1. High speed air flow can produce high velocity and impact strength on black silicon carbide powder, which can produce micron and even submicron ultrafine powder.

 

2. The product has high purity and little pollution.

 

3. The product has narrow particle size distribution, smooth particle morphology and good particle dispersion.

 

In order to obtain the accurate classification of black silicon carbide powder, it is uneconomical to increase the speed of grading wheel only. It is also necessary to control the proportion of auxiliary air and main air volume reasonably. When the system operates with relatively small air volume, adjusting the speed of classifier wheel is more sensitive to the change of particle size. However, the reduction of total air volume will lead to the reduction of treatment capacity, which is obviously uneconomical. Therefore, the advantages and disadvantages of the system should be considered and the optimal operating parameters should be selected.

 

With the expansion of market demand, the production requirements of black silicon carbide are higher and higher.
