What should I do if the powder is not evenly dispersed? The SLG type continuous powder surface coating modification machine is here to solve the problem!

In the field of powder processing and application, “uneven dispersion” is a common problem that plagues many enterprises. Whether it is plastic filling, coating preparation, or the production of pharmaceutical excipients and new energy materials, if the powder shows agglomeration, caking, or uneven dispersion, it will not only directly affect the product performance (such as the decrease in coating gloss and the reduction in plastic mechanical strength), It will also lead to a decrease in production efficiency, serious waste of raw materials, and even cause malfunctions in subsequent processing links. Facing this pain point, the SLG type continuous powder surface coating modification machine, with its efficient, stable and precise modification technology, has become the preferred equipment for solving the problem of powder dispersion.

What are the hazards of uneven powder dispersion?

Product quality not meeting standards: Taking calcium carbonate-filled polypropylene as an example, if the calcium carbonate powder is unevenly dispersed, it will form “agglomerated particles” inside the plastic, resulting in color differences and spots in the finished product, and a significant decrease in impact strength and tensile strength, which cannot meet the demands of downstream customers.

Low production efficiency and high cost: Unevenly dispersed powder is prone to clogging pipelines and equipment during the mixing and conveying processes, requiring frequent shutdowns for cleaning. This not only delays production progress but also increases equipment maintenance costs. Meanwhile, in order to improve the dispersion effect, enterprises often need to add a large amount of dispersants additionally, further pushing up the cost of raw materials.

Poor process stability: In the production of coatings and inks, uneven dispersion of powder can lead to large fluctuations in slurry viscosity, and problems such as sagging and pinholes are prone to occur during subsequent coating. During the production process, process parameters need to be repeatedly adjusted, making it difficult to achieve stable mass production.

The root cause of these problems, essentially, lies in the excessively high surface energy of the powder and the mismatch of polarity, which leads to mutual attraction between particles and the formation of agglomeration. The core function of the SLG type continuous powder surface coating modification machine is to change the physical and chemical properties of the powder surface through “precise coating modification”, fundamentally solving the dispersion problem.

SLG Series Continuous Powder Surface Coating Modification Machine

Product Features:

This machine features a uniquely designed modification chamber that integrates both modification and deagglomeration functions. It is suitable for modifying a wide range of materials, such as heavy and light calcium carbonate, various types of kaolin, talc, wollastonite, quartz powder, mica, silica, titanium dioxide, zinc oxide, alumina, magnesium hydroxide, barium sulfate, illite, pyrophyllite, tremolite, etc., achieving excellent surface modification effects.

Working Principle:

The surface treatment of powder is primarily accomplished within three modification cylinders arranged in a triangular formation. Dry powder and precisely metered modifying agents are simultaneously fed into these cylinders. Driven by the high-speed rotation of the rotor, the materials enter a fluidized, spiral-flow state. The modification and film formation occur rapidly due to the heat generated by the high-speed collisions, friction, and shearing actions between the powder particles and against the fast-rotating rotor.
