The NDM/M series dynamic mixer is a continuous dynamic mixing equipment specially designed by Langxing for the process routes that require mixing, grinding, and emulsification coordination of coatings, paints, and similar materials. The equipment adopts a high-strength stator rotor cooperative shear structure, which effectively disperses, grinds, and finely emulsifies multiphase systems such as pigments, fillers, resin liquids, solvents, and additives under the joint action of high-speed rotation of the rotor and reverse motion of the stator, significantly improving the batch consistency and color paste stability of the product.
This series covers typical application scenarios such as water-based coatings, solvent based coatings, UV coatings, inks, colorants, and adhesives. It is the core process equipment for coating and paint production enterprises to achieve efficient, continuous, and stable production.
Core function: Three in one mixing, grinding, and emulsification
The NDM/M series creates strong shear, impact, and high-frequency turbulence fields between the stator and rotor, enabling simultaneous macroscopic mixing of multiphase materials, grinding and dispersion of aggregates, and fine emulsification of oil-water phases in one pass, greatly simplifying the process flow and significantly improving the consistency of end products.
Typical manifestations:
The aggregates of pigment fillers are efficiently ground and dispersed, the fineness of the color paste is stable, and the batch color difference is significantly reduced;
Resin and solvent are uniformly mixed within milliseconds, avoiding the common local excessive concentration and floating color in traditional stirring;
The oil-water two phases form a stable lotion under strong shear, with concentrated particle size distribution, and no demulsification or layering during long-term storage.
Main technical features
High shear grinding, stable dispersion fineness
The high-strength fixed rotor structure provides continuous and uniform strong shear force, which can efficiently grind the aggregates of pigments and fillers to the target fineness, with stable dispersion effect. The consistency between the fineness and hue of the color paste is significantly better than that of traditional mixing equipment.
Mixing and emulsification synergy, one-step process completion
Simultaneously achieving macro mixing and fine emulsification in a single device eliminates the need for pre mixing tanks and high shear emulsification tanks in traditional processes, shortens the process path, and reduces equipment investment and land occupation.
Concentrated particle size distribution enhances product stability
The high-frequency turbulent flow field and strong shear action make the particle size distribution of droplets or pigment particles more concentrated, significantly improving the coating’s coverage, flowability, storage stability, and application performance.
Heavy duty structure, suitable for high solid content working conditions
The main body of the equipment adopts a heavy-duty design, with outstanding mechanical strength and wear resistance, which can cope with high solid content, high viscosity pigment and filler slurry, as well as long-term operation requirements for continuous production.
Modular design, easy maintenance
The structure is simple, easy to disassemble, and the key stator and rotor components are easy to maintain, which can greatly shorten the maintenance and replacement time and meet the high availability requirements of continuous production equipment.
Typical application scenarios
Grinding, dispersion, and paint adjustment of water-based coatings and latex paints for interior and exterior walls;
Mixing and dispersion of solvent based industrial coatings, automotive coatings, and anti-corrosion coatings;
Fine mixing of UV curable coatings and special functional coatings;
High fineness grinding and dispersion of inks, colorants, and dyes;
Mixing and emulsification of adhesives and sealants;
Other fine chemical processes that require simultaneous mixing, grinding, and emulsification.
