Production-scale milling and screening system
Achieve precise particle size distribution and high throughput rates with a modular system designed for efficient milling, delumping, and security screening—all while minimizing contamination risks and maintaining product integrity.

Processes and Screens Powders for Consistent Particle Sizes
The SDx™ Series from Quadro and Fitzpatrick offers a versatile production-scale milling and screening solution tailored for diverse industries including pharmaceuticals, nutraceuticals, food, chemicals, and cannabis. This innovative platform integrates seamlessly into your production line with its interchangeable heads, enabling conical milling, hammer milling, and delumping from a single base. The SDx™ Series excels in producing tight particle size distributions critical for active pharmaceutical ingredients, oral solid dosage forms, protein powders, and more.
With SMARTdetect™ technology, the system automatically recognizes the installed head and adjusts settings, ensuring optimal performance and reducing setup time. The SDx platform supports high throughput, capable of processing up to 20,000 kg/hr, making it ideal for large-scale operations. Energy efficiency is enhanced through the use of a greaseless sanitary gearbox, lowering operating temperatures and contamination risks while ensuring consistent operation.
Available in stainless steel and other corrosion-resistant materials, the equipment meets ATEX and GMP compliance standards, affirming its suitability for demanding environments. Easy-to-clean designs with modular construction facilitate maintenance, while customization options like variable screens and impellers align with specific production needs. Comprehensive engineering support ensures the equipment is tailored to your specific process requirements.
