Powder mixing is a common operation in industrial production, which is widely used in the chemical industry, pharmacy, food, and construction. It is one of the most critical operation procedures in the production of medicines, feed, cement, and other products. Powder material mixing refers to the operation process in which a variety of powder particles with different components change their moving speed or direction in the mixer, and finally, make the particles with different components randomly and evenly distributed in the mixer.

Solid preparations of solid beverages, health food and drugs all need to mix the components of solid powder. The proportion of components in the formula can reach 80%-90%, and the proportion of components is less than 1%. The forms are powdery, granular and flaky.

Mixed granulation process is a very important link in sintering production process. High intensity mixing is to mix all kinds of materials in the batching process evenly. Granulation is to make materials into mixed materials with appropriate particle size and good air permeability.

It is necessary to ensure that foamed acid (foamed dilute sulfuric acid formed after the liquid formed by mixing concentrated sulfuric acid, water and foaming agent is foamed by compressed air) fully wetts the lint on the surface of cotton seed, The mixing quality of cotton seed and foamed acid is directly related to the consumption of concentrated sulfuric acid, water and foaming agent, and affects the productivity of subsequent drying and defoiling equipment and the amount of residual acid in seeds.

The stirring system of VKM-5 Twin-shaft differential vertical kneader consists of mixing kettle, solid paddle and hollow paddle. The inner wall of the mixing kettle is a hollow thermal insulation layer, which is filled with 30 ℃ constant temperature water provided by the water supply system. The hollow paddle and the solid paddle are vertically installed.

Forced conveying device with mixing function is one of the important equipment in plastic extrusion production line. The device adopts a screw with left and right rotation, driven by a deceleration motor. The materials at both ends of the screw are simultaneously transported to the middle of the screw by utilizing the conveying mechanism of the screw thread. When the materials transported in the left and right directions merge in the middle of the screw, some materials are forcibly transported to the processing equipment through the material conveying port which is in the middle of the mixing bin. Thus realizing the forced conveying function of the materials.
