The horizontal screw belt mixer is a common powder mixing equipment widely used in industries such as pigments and metallurgy, and can also be referred to as a pigment metallurgy mixer or powder machine. Here is a detailed introduction about it:

　　structural composition

　　It mainly consists of a U-shaped cylinder, spiral stirring blades, and transmission components. Spiral shaped blades are generally double layered, with the outer spiral collecting materials from both sides to the center, and the inner spiral conveying materials from the center to both sides. The cylinder cover can be made into an arch or fully open shape, and the discharge form is generally a pneumatic flap valve. A jacket can also be added outside the cylinder for heating or cooling.

　　working principle

　　When the spiral belt on the mixing shaft moves, the inner spiral belt pushes the material to both sides, and the outer spiral belt pushes the material inward from both sides, causing the material to mix back and forth. At the same time, some of the material moves along the axial and radial directions under the scraping of the spiral belt, forming a convective cycle, thus achieving rapid and uniform mixing of the material in a short period of time.

　　feature

　　High mixing uniformity: Through convective mixing of the inner and outer screw belts, the material can achieve high mixing uniformity in a short period of time.

　　Wide adaptability: It has good mixing effect on viscous or cohesive powder particles, low-density fine particle materials, fibrous materials, and paste materials, and can also add liquids to powder particles.

　　Easy operation and maintenance: The screw belt spindle is connected to the drive shaft flange, making it easy to repair or replace the mixing shaft; The cylinder cover is flexible in form and fully open for easy cleaning; The discharge valve has reliable sealing and no leakage.

　　Application field

　　Widely used in industries such as chemical, pigment, metallurgy, medicine, food, and feed, it can be used for material mixing between solids (powder to powder) and solids to liquids (powder to slurry). For example, in pigment production, various pigment powders can be uniformly mixed with additives; In the metallurgical industry, it can be used to mix materials such as metal powders and additives.

　　Key selection points

　　Volume: Choose the appropriate volume according to the production scale. The feeding volume is generally 40% -70% of the cylinder volume, and the optimal feeding amount is 60% of the cylinder volume.

　　Material: Select according to material characteristics, such as carbon steel material for the whole machine, stainless steel material for the parts in contact with the material, etc.

　　Discharge form: Pneumatic flap valve, spherical valve, etc. can be selected, determined according to actual needs and material characteristics.

　　Heating or cooling requirements: If heating or cooling of materials is required, models with jackets can be selected and configured accordingly according to the different heating or cooling media.
