Particle size reduction air conveying system
Achieve precise particle size reduction and contamination-free processing for specialized applications, ensuring optimal quality in high-grade powders and coatings.

Reduces Particle Size and Applies Coatings
The RINA Jet Mill from Riera Nadeu is designed for precise particle size reduction and coating applications across industries like pharmaceuticals, biotech, and chemicals. By utilizing an air conveying system within a circular classifier, it effectively micronizes powders and granulates to below 10 µm without mechanical shocks, ensuring product integrity and non-contamination. This system is ideal for producing inhalable powders, pigments for coatings, and catalysts. With a throughput ranging from 0.1 to 300 kg/h, it offers customizable pressure settings for tailored operations. The modular design and closed-loop nitrogen circuit option make it adaptable for explosive environments, while the absence of moving parts minimizes maintenance needs. Available liners in materials such as high alumina or tungsten carbide enhance its durability against abrasives. Additionally, the equipment complies with stringent emission standards, making it suitable for safe, efficient operation in various industrial settings.
