The metal powder 3D printing technology has high requirements for the flowability and moisture content of the powder. In order to solve the problems of poor flowability and high moisture content of the powder, our company has developed an automatic metal powder drying equipment. The equipment is powered by a high-pressure fan to circulate the metal powder. During the powder circulation process, the drying gas generated by our self-developed drying integrated system dries the metal powder, thereby removing the moisture in the powder. It is suitable for various metal powders. This product is designed as an explosion-proof equipment and can be certified by a third-party authoritative certification machine to ensure that its explosion-proof performance meets relevant regulations.
