Inert gas protective gas flow grinding isolate oxygen. Before the equipment is started, the air in the closed circulation system is started, and the air is closed, and the discharge system can be replaced with a small amount of air brought by the addition and discharge process, and maintains the content of the system in the system. In the process, the oxygen content tester continuously monitors the oxygen content in the airflow, and nitrogen is supplemented immediately when it exceeds some extent, so that the oxygen content is always maintained within the safety production standard.Currently, the development of the graphite powder market is getting better and better. Graphite powders are widely used in many industries, especially the development of 5G industries. Grainne can be used to reduce the heat of 5G mobile phones. The processing of graphite powder typically uses airflow classifiers to select a suitable powder granularity section, thereby making subsequent industrial chains play a greater value.
The initial particle size distribution of the graphite powder is widely distributed. In order to obtain a certain particle size powder, the graphite is sent to the inner hierarchy ultrafine powder grinding machine, and the inner grading turbine is rotated, qualified particle size When the gas flow is automatically flowing, the crude particles fall into the crushing area to continue to break until qualified. The qualified graphite powder flows into the centrifugal grading machine with the airflow. The particle size is less than a certain size of the powder is discharged from the airflow separator to the cyclone, the coarse powder is discharged from the reel. The collected graphite powder is sent to the transition barrel, and the material is sent into the graphite molding machine through the transition barrel spiral feed system. It is preferred to feed the graphite into a plurality of graphite molding machines to obtain spherical graphite.
The application of airflow classifier in graphite powder overcomes complex preparation process, uneven product quality, low finished product rate, high energy consumption, high production cost. An ultrafine powder mill of an internal hierarchy is proposed. It replaces a multi-air current pulverizer to achieve a grinding, and the number of spherical graphite is simplified by a parallel forming system composed of a plurality of graphite forming machines. Simple process, high level control precision, narrow powder particle size distribution, stable quality. The compact device is small, which is the shortest production line in my country. Low energy consumption and high yield productivity will not cause pollution to the environment.
