Grinding Equipment for Coating Production

Wet Grinding Technology

Fineness Requirements vary from different types of coatings. Through wet grinding, various solid components in the coating (pigments, binders, additives, etc.) are refined to a suitable particle size, thereby improving the covering performance and color vibrancy of the coating. For example, when producing those with high technical standards on particle size, like printing inkjet and electronic coatings, bead mills are ideal for fine particle sizes and particle distributions.

Our fine powder grinding machine covers different specifications, from microns, submicrons, and ultrafine nano scale grinding. By adjusting the size of the grinding media, filling rate, grinding circulation and other parameters, the particle size can be precisely controlled and reach ultrafine nano range.

Dispersion and Mixing

Uniform mixing can prevent the pigments or coloring components from agglomerating and settling during storage, transportation, and use, especially for coating components with a large difference in density. The fillers with an even distribution can also enhance the hardness, wear resistance, and corrosion resistance.

LONGLY emulsifier and paint mixer machine can disperse raw components including resins, pigments, and fillers under the combination of strong reciprocating shear force, collision, etc., by controlling the speed of the stator or rotor or stirring paddle, and adapt to various viscosities. The products with uniform distribution have smoother fluidity, better flawless adhesion and less sagging. 

Industrial Paint

Industrial paint is specially formulated to protect and enhance the surfaces of substrates and machinery. Common types include automotive paints, marine paints, machine paints, and furniture paints.   

LONGLY wet grinding technology and paint agitator machine can enable the paint produced with fine particle size under more reasonable distribution, resulting in more stable film formation. The ultimate product has excellent protective and decorative effects for long durability.

Functional coatings

Functional coatings provide not only the protection and decoration of the conventional coating but also technical functions such as oil resistance, water resistance, heat resistance. Common types include conductive coatings, anti-corrosion paints, and antimicrobial coatings.

Our bead mill enables precise control of the particle size and distribution of the coating materials. Homogenization and dispersing the materials using our mixer ensures the active ingredients in the coating can better contact and react, forming a denser coating.

Powder coating

Powder coating, different from traditional liquid coating, is a new type of solvent-free solid powder coating composed of solid resin, pigment, filler and additives. It is characteristic of high efficiency, environmental protection, and high utilization rate.

Our dry powder grinders and latest powerful mixer can obtain powder with smaller particle size and narrower distribution, to improve the coating powder adsorption efficiency. Particles of similar size exhibit more consistent movement and charging performance during electrostatic spraying, enhancing adhesion and tack to the surface.

LONGLY chemical processing equipment for coating revolutionizes traditional processes. No matter what stage, feeding and metering, grinding and dispersion, or filling and palletizing, is managed and controlled in the integrated. The high automation of our lab mixing equipment, industrial paint mixer, and agitator bead mill can easily handle different continuous scale production, bringing a qualitative leap to your coatings.
