Conical mill for high-capacity powder milling
Optimize your powder milling process with efficient conical milling systems designed for precise particle size control and high-product recovery, ensuring minimal waste and maximized throughput.

Processes and Reduces Particle Size for Various Applications
The Underdriven Comil Series from Quadro Engineering is a suite of conical milling solutions tailored for efficient powder processing across pharmaceutical, nutraceutical, and food industries. This equipment excels in reducing particle size and deagglomerating materials with its unique underdriven design, facilitating compact integration in production lines. Featuring a scalable capacity ranging from lab-scale to production-scale, it can process up to 35,000 lb/hr of material. Its inline tri-clamp design ensures seamless installation, while the absence of spacers enables quick changeovers of impellers and screens, maintaining high throughput with minimal downtime.
The Underdriven Comil is engineered for energy efficiency, optimized by variable-speed motor control, and is available with specialized tooling for heat-sensitive products. Constructed with stainless steel, it meets cGMP standards, ATEX, and UKEX certifications, ensuring compliance for use in potentially explosive atmospheres. The equipment supports closed-system processes, essential for pharmaceutical-grade manufacturing, and includes clean-in-place (CIP) capabilities for rapid and contamination-free maintenance, offering both operational excellence and regulatory compliance.
