Technical Field

[0001] The utility model relates to the field of conveying devices, in particular to a powder material spiral conveying device. Background Art

[0002] Powders are easy to float and spread, thus polluting the workshop environment. Long-term inhalation of floating powders by workers will cause damage to their health.
