Over-driven conical mills for precise particle size reduction
Achieve consistent particle size reduction with minimal heat generation, perfect for processing heat-sensitive materials. Ideal for integrating seamless wet or dry milling into continuous production lines, enhancing efficiency and product quality.

Reduces Particle Size through Shearing and Compression
The Uni-Mill B-Series from Hanningfield offers a robust solution for precise particle reduction through its over-driven conical milling design. Using a belt-driven impeller, the Uni-Mill compresses and shears material to achieve efficient size reduction with minimal heat generation, making it ideal for processing pharmaceuticals, nutraceuticals, and chemicals. With models ranging from the M10-B to the M60-B, it caters to varying throughput needs, from low to high capacity, handling up to 7200 kg/hr. The stainless steel construction ensures compliance with FDA standards, while ATEX options offer enhanced safety for explosive environments. Its adaptable design supports both wet and dry milling, integrating seamlessly into continuous, automated production lines. Customizable features, including screen variability and inlet and outlet configurations, offer further flexibility, supported by comprehensive validation documentation (FS/DS, FAT, SAT, IQ/OQ) and CIP systems for easy maintenance.
