Ceramic contact surfaces
Liners and selected components reduce direct metal contact in critical areas.
Low-Contamination Grinding
Ceramic-Lined Jet Milling System
A ceramic-lined jet milling and classification system for high-purity powders and materials with strict metallic-contamination limits.
Process Overview
Control contamination across the complete powder contact path
Low contamination depends on more than one ceramic liner. The milling chamber, classifier wheel, nozzles, conveying path, valves, collection parts, sealing structure, and maintenance method must be reviewed as one system.
Final configuration is determined from representative powder data, required product quality, throughput, operating environment, and safety information.
Key Technical Features
Each item is reviewed against the real powder and acceptance criteria.
Low-temperature jet milling
Compressed gas provides grinding energy without mechanical grinding media.
Precision classification
Classifier speed and airflow control the final particle-size distribution.
Clean collection path
Sealed collection and suitable filters help reduce secondary contamination.
Material-specific protection
Ceramic grade and protected area are selected from hardness and impurity limits.
Wear review
Trials and inspections establish practical wear and maintenance boundaries.
Typical Applications
Battery cathode and anode powders, alumina, zirconia, silicon nitride, electronic ceramics, pharmaceutical powders, and other high-purity materials.
Application examples are not a guarantee for an untested powder. Chemical compatibility, dust risk, and required product properties must be confirmed first.
Before Selection
Send the material name, SDS, feed PSD, target D50/D90/D97, capacity, impurity limits, temperature limit, and atmosphere requirements.

Frequently Asked Questions
Does ceramic lining eliminate all contamination?
No. It reduces selected contamination sources, while feed quality, seals, filters, handling, and cleaning still affect the result.
Which ceramic material should be used?
Alumina, zirconia, silicon carbide, and other options have different wear, purity, and cost characteristics. Selection follows the powder and impurity limit.
Why is sample testing important?
It provides particle-size, wear, buildup, cleaning, and collection evidence before the production configuration is fixed.
Confirm the process with your actual powder
Testing helps establish achievable particle size, capacity trend, collection behavior, contamination risk, and the correct system boundary before production selection.
