Industries We Serve
Norstone, Inc. supplies grinding medias, dispersing impellers and mixing blades, and processing equipment to manufacturers, processors, and laboratories across a wide range of industries. Applications range from pigment and coatings dispersion to pharmaceutical and nutraceutical particle size reduction to battery material processing. Each industry served has different priorities around contamination control, particle size targets, cost sensitivity, and regulatory considerations, which influence which grinding media family, blade type, and equipment configuration can be recommended.
Industries with strict purity requirements, such as pharmaceuticals, cosmetics, and food processing, might favor polymeric or ceramic grinding medias, while industries processing dark materials or hard minerals with no color or iron specification may use steel or exotic medias. There are always exceptions, such as the chocolate industry, which prefers carbon steel balls due to their high density, easy removal with magnets, and iron fortification to the diet. Each industry page below links to guidance specific to that industry’s particle size reduction needs.
Industries Served
Paints & Coatings
Uses grinding media and dispersing blades for pigment grinding, affecting color development, gloss, and dispersion stability. Many additives in these industries also require particle size reduction and well incorporated powders with liquids.
Inks & Toner
Requires fine, consistent particle size reduction for pigment dispersion, printability, and reliable color strength. Optimum grinding is necessary for rollers to stay smooth and viscosity to remain consistent.
Pharmaceuticals
Uses particle size reduction for active ingredients and excipients, often with strict contamination control requirements. Particle size reduction can expose more surface area, aiding in more efficient absorption.
Cosmetics & Personal Care
Relies on particle size reduction and dispersing for pigments, actives, and texture-critical ingredient formulations. Particle size reduction can enhance colors and extend pigments, whether it's lipsticks or nail polish.
Chemicals
Uses grinding media and dispersing equipment for grinding and fine chemical particle size reduction.
Minerals & Ceramics
Uses grinding media for raw material milling and ceramic slip grinding, where hardness affects efficiency. There is a boom in ultra ground mineral and technical ceramic products displaying new properties as particles are reduced to the nano size range.
Batteries & Energy
Uses particle size reduction for cathode and anode material processing, affecting downstream battery performance, thus extending the life of batteries by exposing more of the surface area.
Food & Chocolate
Uses particle size reduction and refining for texture and consistency, often requiring food-grade milling media. Particle size can greatly affect the taste and tongue experience, so consistency is critical.
Nutraceuticals
Uses wet milling and particle size reduction for supplement ingredients, prioritizing contamination control similar to pharma.
Automotive
Uses grinding media and dispersing equipment for almost every part of the automobile, from the paint to the windshield coating, seat covers to the catalytic converters.
Pigments & Dyes
Uses grinding media and dispersing blades for color particle size reduction, directly affecting color strength. Particle size reduction further develops the color by exposing the surface areas of organic and inorganic pigments and dyes.
How Industries Select Grinding Media and Equipment
Industry-specific requirements typically drive three decisions: which grinding media family fits the contamination and heat tolerance and hardness needs of the process, which blade or impeller type suits the viscosity, chemistry and volume of the material being processed, and which mill or disperser configuration matches the target particle size and production scale.
Regulated industries, including pharmaceuticals and food processing, often prioritize low-contamination grinding media and equipment with straightforward cleaning and documentation. Industries focused on color and appearance, such as paints, coatings, inks, and pigments, generally prioritize fine and consistent particle size reduction to achieve color strength, gloss and dispersion stability. Industries processing raw or mineral materials, such as minerals and ceramics processing, generally consider hardness and wear resistance in addition to contaminants such as metal, which can cause graying and add black spots to the finished product.
Because these priorities vary significantly by application even within a single industry, the Grinding Media Depot Selection Guide and a direct quote request remain the most reliable way to confirm the right combination of products for a specific process. In most cases, visual samples can be provided as well.
Products by Application
Industries served by Norstone, Inc. typically rely on a combination of products from the Grinding Media Depot for particle size reduction, the Blade Depot dispersing impellers and mixing blades for mixing and dispersing steps, and Particle Size Reduction Process Equipment including mills, dispersers, rotor-stators and mixers for the overall process. Product selection varies by industry based on contamination tolerance, target particle size, process volume, and any applicable regulatory requirements, and is best confirmed through completion of a process application form or contacting Norstone directly to assist with a comprehensive solution.
