1. Project Background
The client is a prominent agrochemical manufacturer in India specializing in Imidacloprid, a highly effective systemic insecticide. The biological efficacy of Imidacloprid—specifically its rapid action and stability in formulations like Wettable Powders (WP) and Suspension Concentrates (SC)—is directly dependent on its particle size and specific surface area.
To maintain a competitive edge, the client required a solution for the ultra-fine grinding of imidacloprid to achieve sub-10μm fineness while maintaining a high industrial throughput.
2. Technical Solution: Epic Powder Jet Mill System for Ultra-Fine Grinding of Imidacloprid
After rigorous material testing, the client selected the Epic Powder Fluidized Bed Jet Mill. This system was chosen for its ability to handle heat-sensitive organic compounds without degrading the active ingredient.
Key Equipment Advantages:
- Contamination-Free Grinding: The material is pulverized through high-velocity particle-to-particle impact, ensuring maximum product purity.
- Integrated Classification: A built-in high-precision vertical turbine classifier ensures a sharp particle size distribution (PSD) and prevents over-grinding.
- Cool Temperature Operation: The cooling effect of compressed air expansion offsets the heat generated during grinding, making it ideal for the low melting point characteristics of certain agrochemicals.
3. Key Outcomes
- Precision at Scale: Achieving a D97 of 7.99μm at a consistent output of 110 kg/h is a significant benchmark for large-scale Imidacloprid production.
- Narrow PSD: The narrow particle size distribution significantly enhances the suspension rate and dispersibility of the final pesticide formulation.
- Energy Efficiency: Optimized nozzle geometry reduced compressed air consumption, leading to lower operational costs per ton of material processed.
