Particle Size Reduction Equipment
Halden designs and builds wet and dry attrition mills used to refine pigments, actives, powders, and slurries across paints, food, pharma, technical materials, battery, and energy production.
Markets We Serve
Every material has a size at which it performs. We help process engineers find it and hold it, batch after batch.
Pigment dispersion and let-down milling for gloss, tint strength, and stable rheology across solvent and waterborne systems.
Chocolate, nut paste, and flavor milling built to hygienic standards, with mouthfeel controlled to the micron.
Active ingredient micronization for bioavailability, with contained, validatable, repeatable processes.
Ceramics, carbides, and engineered powders milled to tight particle distributions for demanding tolerances.
Cathode, anode, and electrolyte slurry milling tuned for consistent particle morphology at production scale.
Fine grinding for catalysts, coal-water fuel, and alternative energy feedstocks under continuous duty cycles.
Equipment
Every line is available as a lab unit for trials and scales directly into production, so results never have to be re-proven.
Batch, circulation, and continuous configurations for slurries, dispersions, and suspensions.
Fine grinding of dry powders without solvent, built for abrasive and heat-sensitive materials.
High-throughput circulation milling for inks, coatings, and high-viscosity dispersions.
Sub-ambient grinding for elastomers, waxes, and heat-sensitive polymers that gum at room temperature.
How a Project Runs
Each stage produces the data the next one needs — no step is skipped, no scale-up is guessed at.
You describe the material and the target particle size. We recommend a mill architecture and media.
We run your material on a lab-scale mill and report particle size distribution within 24 hours.
Trial parameters are converted to production-scale settings — same result, larger batch.
Your mill ships, installs, and runs to the same distribution the lab trial proved out.
Get Started
Send us your material and target particle size. We'll tell you which mill gets you there and what it costs to prove it.
