Processing large rubber solids—particularly chunks measuring up to two inches (approximately 50 mm)—presents significant challenges in industrial dispersion operations. Whether producing rubber solutions for adhesives, coatings, sealants, or specialty elastomeric formulations, traditional equipment often requires pre-shredding, prolonged mixing cycles, multiple process stages, and high energy input. These methods generate excessive heat, increase solvent losses, and result in inconsistent particle-size distributions.

Kady International’s high-speed precision rotor-stator dispersion mills overcome these limitations by delivering concentrated impact and attrition forces capable of rapidly reducing two-inch rubber chunks to fine, uniform dispersions in a single vessel and in a fraction of the time required by conventional systems. Operating at rotor tip speeds of up to 9,000 feet per minute (FPM), the Kady Mill fractures, wets, and disperses large rubber solids efficiently while maintaining process control and product quality.

Kady International’s high-speed rotor-stator dispersion mills deliver unmatched solids loading capabilities — up to 75% clay and 65% TiO₂ — while producing superior dispersion quality in dramatically less time.

Why High Solids Loading Matters

In the coatings, paint, ink, and chemical industries, the ability to disperse higher percentages of solids directly impacts profitability. Higher solids mean less water or solvent, lower shipping costs, faster drying times, and improved product performance.

The production of additives, emulsions, and dispersions with oil requires precise mixing to achieve uniform consistency, stability, and performance in applications ranging from coatings to cosmetics. Kady International, a Scarborough, Maine-based leader in industrial mixing since 1949, offers high-speed rotor-stator dispersion mills and mixing systems that simplify these processes. Operating from a 50,000-square-foot facility, Kady’s innovative equipment, used in over 40 countries, delivers efficient, high-quality results for fluid-based applications. Their mixers streamline the creation of oil-based additives, emulsions, and dispersions, ensuring consistency and scalability for industries like paints, pharmaceuticals, and food processing.

Custom milling and mixing equipment, such as those developed by Kady International, offer significant benefits for continuous processing systems, particularly in industries that require high-efficiency and high-quality output. These mills are designed to integrate seamlessly into continuous production lines, providing a consistent, uninterrupted flow of material. By using rotor-stator technology, Kady's equipment ensures precise and uniform dispersion of solid materials into liquids, resulting in high-quality products with enhanced texture and consistency.

The production of high-quality flexographic and rotogravure inks requires precise mixing, dispersion, and homogenization to achieve consistent color, viscosity, and performance for printing applications. Kady International, a leader in industrial mixing technology since 1949, provides advanced high-speed rotor-stator dispersion mills and mixing systems that streamline the ink manufacturing process. Based in Scarborough, Maine, their 50,000-square-foot facility produces innovative mixers, including top and bottom entry batch mixers and continuous flow mills, used globally in over 40 countries. These systems ensure superior ink quality for the printing industry, particularly for flexographic and rotogravure inks used in packaging, labels, and high-end graphics.

Producing vibrant, consistent liquid colors for industries like paints, coatings, and inks requires rapid and precise mixing to achieve uniform pigment dispersion and stable formulations. Kady International, a Scarborough, Maine-based leader in mixing technology since 1949, offers high-speed rotor-stator dispersion mills and mixers that streamline this process. Operating from a 50,000-square-foot facility, Kady’s equipment, used in over 40 countries, delivers efficient, high-quality results for liquid color production. Their innovative systems ensure quick, uniform mixing and dispersion, meeting the demands of industries requiring superior color consistency and performance.

Superior dispersion for high-solids paper coating formulations

In the competitive world of paper manufacturing, the quality of the coating directly determines printability, gloss, smoothness, brightness, and overall value of the final sheet. Achieving a consistent, high-solids coating color with excellent pigment dispersion is critical — and that’s exactly where Kady International rotor-stator mills excel.

Maximum color strength and superior dispersion with Kady International rotor-stator mills

Phthalo Blue is one of the most widely used organic pigments in the coatings, ink, and plastics industries. Known for its intense tinting strength and excellent lightfastness, it is also notoriously difficult to disperse due to its strong tendency to form agglomerates.

Traditional mixers often require 2 to 6 hours to fully develop Phthalo Blue. With a Kady high-speed rotor-stator mill, the same pigment typically reaches full color development in just **45 minutes**.

The High Cost of Poor Dispersion

Pigments are often the most expensive component in paints, inks, coatings, and liquid color formulations. Traditional high-speed dissolvers and lower-shear mixers leave many pigment agglomerates intact, wasting expensive raw material. Manufacturers compensate by adding 10–30% more pigment to reach target color strength, gloss, and opacity — directly inflating costs and extending production cycles.

In the manufacture of paints, coatings, inks, adhesives, and specialty formulations, the efficient dispersion of vinyl resins, nitrocellulose (NC) chips, and high-solids water pastes remains one of the most demanding process steps. These materials present unique challenges: high density chips that settle rapidly, tendency to agglomerate or become tacky upon solvent contact, high viscosity water pastes, and the need for complete deagglomeration without excessive heat generation or solvent loss.

Kady International’s high-speed precision rotor-stator dispersion mills solve these challenges by delivering intense impact and attrition forces that reduce vinyl chips, nitrocellulose chips, and water pastes to their ultimate particle size in a matter of minutes rather than hours. Operating at rotor tip speeds of up to 9,000 feet per minute (FPM), the Kady Mill achieves stable, uniform dispersions in a single step, frequently eliminating the need for multi-stage premixing, grinding, and letdown operations.
