3D printing powder sieving machine is designed to revolutionize your metal powder recycling process by using a vacuum to extract powder from the print bed and then sieving the powder for future use.
The powder is separated from the airflow by gravity drop and surface filters, and discharged into a buffer hopper, which meters the powder onto the screen deck of the sieve. Here, larger powders and agglomerates are separated from smaller particles; the smaller particles pass through the screen and screen outlet into a collection container (assisted by an ultrasonic generator that enhances powder flow), making them immediately available for reuse. Typical metal powders include Inconel, Stainless Steel, Cobalt Chrome. Using a vacuum system, the powder is extracted, conveyed to a vacuum receiver, and the powder is discharged into a sieve, which then discharges the metal powder into a barrel in a closed, inert environment.
1. Equipped with an ultrasonic sieving system, which can transmit ultrasonic frequency to the sieve, allowing the sieving to be as fine as 25µm/500 mesh without clogging the sieve holes, which can ensure fast processing of difficult and brittle powders.
2. The closed system can be purged with inert gas to isolate the contamination-sensitive powder from ambient air and moisture, reducing cross-contamination of the powder, eliminating the operator having to touch the powder and ensuring a safer environment.
3. Hygienic stainless steel construction eliminates dead spots, allowing complete evacuation and easy cleaning.
4. The screened powder can be reused immediately, mixed with virgin materials, stored or recycled.
Metal powder recovery systems recover and recondition used powder to precise particle sizes, reducing waste and operating costs while preventing product and plant environment contamination.
