Technical Field
[0001] The utility model belongs to the technical field of plastic powder production equipment and relates to an air separation device for plastic powder production. Background Art
[0002] Plastic powder, plastic ultrafine powder, resin powder Plastic is a synthetic high molecular compound, also known as polymer or macromolecule, also commonly known as plastic or resin, which can freely change shape and style. It is a material made by synthesizing or condensing monomer raw materials. It is composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants.
[0003] Plastic powder is generally made by grinding plastic particles into powder. During production, the ground powder needs to be filtered and screened to remove the plastic particles that are not fully ground in the powder to ensure the production quality of the plastic powder. The screening methods include filter screening and air separation screening. In air separation screening, the fine plastic powder tends to continue to move with the air flow and is difficult to collect.
