プロジェクト概要
Red Iron Oxide (Fe2O3) is widely utilized as a high-grade pigment and polishing agent. To achieve superior color intensity and surface finish, the material requires extreme fineness and a narrow particle size distribution (PSD). Seeking to upgrade their production capabilities, a client partnered with Epic Powder Machinery to order Red Iron Oxide Jet Mill. They intended to reduce raw material to a sub-2-micron level while maintaining high-volume output and ensuring zero grit contamination.
The Challenge: Balancing Fineness and Throughput
Iron oxide is inherently abrasive. Standard mechanical mills often struggle with:
Tool Wear: Abrasive particles degrade grinding components, leading to frequent maintenance.
Agglomeration: At sub-micron levels, particles tend to clump, making it difficult to achieve a consistent D97.
Heat Sensitivity: Excess heat during grinding can alter the chemical stability and vibrant red hue of the pigment.
The Solution: MQW Series Fluidized Bed Jet Mill
We implemented the MQW Series Fluidized Bed Jet Mill, the gold standard for high-purity micronization. By utilizing high-velocity compressed air, the particles collide with each other rather than the machine liners, effectively eliminating wear and contamination.
統合された high-speed horizontal classifying wheel was calibrated to extract only the particles meeting the strict 1.28μm threshold, returning over-sized material for further grinding.
Experimental Results & Performance
The trial conducted at the Epic Powder R&D center yielded exceptional results, surpassing the client’s expectations for both quality and efficiency.
