ACM mill (air classifying mill / ACM pulverizer) is widely adopted across multiple industries for dry fine grinding and one-step classification. It is preferred for producing powder in the 120–800 mesh range, balancing adjustable fineness, stable PSD, and lower energy consumption compared with jet mills. The core tuning parameters including hammer count, rotor tip speed, airflow and classifier speed can be customized for different industry product requirements.
Main Industries
1. Mineral & Mining Processing Industry
This is the largest application field. Process calcium carbonate, talc, kaolin, diatomaceous earth, quartz, barite, wollastonite, feldspar, dolomite and gypsum.
Products are used as plastic fillers, paint extenders, filter aids, agricultural soil amendments and rubber fillers.
Key requirement: control frustule integrity for diatomaceous earth; wear-resistant liners for silica and abrasive minerals.
2. Powder Coating Industry
ACM is the standard pulverizer for thermoset powder coating production. It grinds extruded resin flakes into sprayable powder with tightly controlled PSD.
Strict limits on oversize particles and excess ultrafine fines to guarantee electrostatic charging, film smoothness and fluidization. Water-cooled chamber is required for heat-sensitive resin.
3. Lithium Battery / New Energy Materials Industry
Process cathode materials: LFP, NCM, LCO, LMO; also ATH flame retardant, precipitated silica, calcined graphite.
Safety requirements: nitrogen inerting, anti-static design, explosion protection, ceramic wear liners to avoid metal contamination of battery powder.
4. Paint, Ink & Pigment Industry
Grind inorganic pigments, iron oxide, titanium dioxide, extender fillers.
Need narrow PSD, controlled fine tail to achieve consistent color strength, gloss and dispersion performance in coatings and inks.
5. Plastic & Rubber Filler Industry
Produce fine mineral powders (CaCO₃, talc, kaolin, wollastonite) as functional fillers for plastic profiles, masterbatch, rubber goods.
Fineness and particle shape directly affect product tensile strength, rigidity and surface quality.
6. Flame Retardant Material Industry
Process aluminum hydroxide (ATH), magnesium hydroxide. Low-temperature grinding prevents thermal decomposition of flame retardant powder, maintains high whiteness and adsorption performance.
7. Ceramic Raw Material Industry
Pulverize alumina, quartz, feldspar and other ceramic raw materials for daily ceramic, industrial ceramic and ceramic glaze powder.
8. Agricultural & Feed Industry
Agricultural diatomaceous earth, mineral feed additives, limestone powder for soil improvement and animal feed supplements.
9. Food & Nutraceutical Industry
Food-grade calcium carbonate, calcium phosphate, brittle shell powder and mineral additives. Equipment adopts sanitary stainless steel, easy-clean structure to meet food contact standards.
10. Chemical & Advanced Material Industry
Brittle precious metal powder (ruthenium), metal oxides, inorganic chemical raw materials. Full containment and dust hazard control are required for toxic or high-value noble materials.
Why these industries select ACM mill
- One machine integrates grinding and air classification, simple process flow
- Flexible fineness adjustment from 120 mesh up to 800 mesh
- Lower specific energy consumption than jet mills for medium fineness
- Modular design: wear protection, water cooling, inert gas system can be configured according to material
ACM mill serves mineral processing, powder coating, lithium battery new energy, paint pigment, plastic filler, flame retardant, ceramic, agriculture, food and fine chemical industries. Each industry tunes hammer configuration, airflow and classifier speed to match their unique powder PSD and product quality requirements.
