Precision Drives Efficiency: FGI FD200 Inverter for Ultra-Fine Jet Milling

Jet mills are widely used in the chemical, pharmaceutical, and food industries for ultra-fine pulverization. The FGI FD200 Compact Inverter offers an ideal drive solution with advanced low-voltage frequency control, enhancing system stability, enabling rapid start-stop, and optimizing overall performance in jet mill applications.

The jet mill system typically comprises a jet mill, cyclone separator, dust collector, and induced draft fan. Compressed air is filtered, dried, and injected at high speed into the milling chamber through Laval nozzles. At the intersection of multiple high-pressure airflows, particles are repeatedly collided, sheared, and fractured.

The pulverized material is drawn upward by the fan-induced airflow into the classification zone, where a high-speed rotating classifier wheel generates strong centrifugal force to separate coarse and fine particles.

• Precision Classification: Optimized airflow design enables particle size control between 1-74 μm (up to sub-micron level)
• Wide Applicability: Suitable for materials with Mohs hardness levels from 1 to 10; ideal for de-agglomerating ultrafine powders
• Compact Footprint: Lab-dedicated models occupy less than 2.5㎡

• HMI: 7-inch full-color touchscreen (800×480 resolution)
• Control Core: PLC communicates with the inverter via MODBUS RTU protocol
• Speed Control: Powered by the FD200 series frequency inverter

• Space-Saving Design: Book-style housing reduces volume by 30% compared to similar products
• Intelligent Control: Built-in PID algorithm for precise process control
• Comprehensive Protection: Overcurrent, overvoltage, and phase-loss protection
• Communication Compatibility: Supports MODBUS industrial protocol for seamless system integration

• Equipment failure rate significantly reduced, lowering maintenance costs
• Installation space reduced by 45%, cutting electrical cabinet costs by approx. 20%
• Improved speed control accuracy with vector control vs. traditional V/F methods
• Enhanced classifier motor precision, increasing product yield and quality

The successful application of the FGI FD200 Compact Inverter in jet milling systems demonstrates its ability to:

1. Solve fine particle size control challenges through high-precision vector control
2. Meet space-constrained application scenarios, particularly in laboratory or pilot-scale production environments

FGI continues to provide efficient, reliable, and compact drive solutions to support the performance upgrade of advanced industrial systems.
