[0002] Secondary zinc oxide is a white to slightly yellow fine powder, mostly obtained by processing intermediate products in the zinc smelting process or zinc-containing waste (such as zinc ash, zinc slag, etc.). In order to maintain the continuity of secondary zinc oxide production, the screw feeder is one of the essential equipment in our production.

[0003] The existing screw feeder for zinc oxide production uses a screw feeder where workers pour the zinc oxide raw materials into the feed port, and the spiral blades rotate to accurately deliver the zinc oxide through the discharge port to the feed port of the production equipment.
