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

FD200 Compact Frequency Inverter for Jet Mill Systems

Precision Control and Compact Integration for Industrial Micronization

Jet mills are widely used in the chemical, pharmaceutical, and food industries for ultra-fine pulverization. To meet the demands of precision control and energy efficiency, the FGI FD200 Compact Inverter offers an ideal drive solution. With advanced low-voltage frequency control, it enhances system stability, enables rapid start-stop, and optimizes overall performance in jet mill applications.

1. Overview of the Jet Mill System

Working Principle

The jet mill system typically comprises a jet mill, cyclone separator, dust collector, and induced draft fan. During operation, compressed air is filtered, dried, and then injected at high speed into the milling chamber through Laval nozzles or similar. 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. Fines that meet the particle size requirement are collected via the cyclone separator and dust collector, while oversized particles fall back into the milling zone for further pulverization.
