1. Project Background
As one of the world’s leading agricultural producers, Brazil maintains extremely rigorous standards for agrochemical products. A major local pesticide manufacturer sought to upgrade its production line to enhance the adhesion and biological efficacy of its herbicide products. The core requirement of the project was to utilize ultra-fine grinding of herbicides technology to significantly reduce the particle size of the active ingredients, thereby increasing their specific surface area.
2. Process Parameters & Challenges
In the agrochemical industry, Particle Size Distribution (PSD) directly determines the suspension rate and spraying uniformity of the product.
- Material: Thermosensitive Herbicide Technical (TC)
- Feed Size: 100μm
- Required Output: D97 = 16.55μm
- Capacity Requirement: 200kg/h
- Core Challenge: The system must precisely control the particle size to 16.55μm while maintaining a high throughput of 200kg/h. Furthermore, the temperature within the grinding chamber must be strictly regulated to prevent any degradation of the herbicide’s physical or chemical properties.
3. Solution: Epic Powder MQW Air Jet Mill
To meet the client’s specific requirements, Epic Powder provided a customized MQW Air Jet Mill system solution.
Technical Advantages:
- Isothermal Grinding: The air jet mill utilizes the cooling effect generated by the expansion of compressed air during the grinding process, perfectly addressing the heat-sensitivity issues common in herbicides.
- Integrated Precision Classification: The MQW series features a high-efficiency vertical classifying wheel, ensuring a narrow PSD and zero oversize particles, achieving the target D97 = 16.55μm.
- Automated Control: Designed for large-scale production in Brazil, the equipment supports fully automated operation, ensuring long-term stability and consistency.
4. Implementation Results
Following installation and commissioning, the system demonstrated excellent performance on-site in Brazil:
- Consistent Particle Size: The final product strictly met the D97 = 16.55μm specification, significantly improving the suspension performance of the chemical.
- High Output: Actual production capacity remained stable at over 200kg/h, meeting the demands of mass production.
- Market Competitiveness: By upgrading the ultra-fine grinding of herbicides process, the client’s products achieved superior spray coverage and longer-lasting efficacy in the Brazilian market.
