In the competitive world of industrial coatings, the difference between a standard primer and a high-performance barrier coating often comes down to the quality of the filler and the precision of the talc 제트 밀링 process. A leading Taiwanese mineral processor faced rising pressure from the coatings sector. Manufacturers required a specialized talc grade to enhance the gloss and barrier properties of premium primers. The client’s previous grinding equipment struggled with two major hurdles:
Inconsistent Particle Size Distribution (PSD): Frequent fluctuations in output quality.
Structural Damage: Mechanical milling often destroyed the talc’s natural lamellar (platelet) structure, stripping away its value as a reinforcing filler.
The Solution: The MQW60 Fluidized Bed Jet Mill
The processor partnered with 에픽 파우더 to implement the MQW60 Fluidized Bed Jet Mill, a system engineered for high-purity, heat-sensitive, and abrasive minerals.
Key Technical Advantages:
Preserved Lamellarity: By utilizing supersonic air streams to drive 입자 간 충돌, the MQW60 delaminates the talc platelets gently. This self-grinding mechanism maintains a high aspect ratio, which is vital for corrosion resistance and structural reinforcement in paints.
Silicon Nitride (Si₃N₄) Classification: The integrated classifier wheel is constructed from high-performance ceramics. This ensures zero metallic contamination (preserving whiteness) and provides extreme wear resistance against abrasive minerals.
Smart Load Monitoring: The system features an integrated weighing module. By continuously adjusting the feed rate based on real-time mill load, it guarantees a repeatable, narrow particle size distribution across every batch.
Results and Performance Impact
The transition to Epic Powder’s technology allowed the Taiwanese processor to move into the high-end coating market with confidence. The feedback from end-users has been exceptional:
Gloss Enhancement: ㅏ 35% increase in 60° gloss readings compared to previous batches.
Improved Suspension: Significantly reduced sedimentation rates in liquid formulations.
Superior Protection: Enhanced salt spray test results, proving better barrier effects against corrosion.
