Description

Technical Field

[0001] The present disclosure relates to the technical field of dry powder mixers, and in particular to a vertical dry powder mixer. Background Art

[0002] Paint is an essential product for decorating walls and other objects. It is a chemical mixture that can firmly cover the surface of an object for protection, decoration, marking and other special purposes. Paint can be divided into oil-based paint, modern paint, synthetic paint and inorganic paint according to the main film-forming substance used in the paint. Paint can be divided into solution, latex, sol, powder, glossy, matte and multi-color art paint according to the form of the paint. In the paint production process, an important step is the mixing of paint raw materials;

[0003] During the coating mixing process, the raw materials are prone to caking, which affects the mixing effect. At the same time, the upper and lower materials are prone to stratification during the mixing process, resulting in uneven mixing. Utility Model Content
