Conical mills for size reduction in pharmaceutical production
Achieve precise particle size control with an innovative milling solution, ideal for both batch and continuous operations, ensuring consistent and scalable results in your production line.
The Uni-Mill U-Series from Hanningfield is a versatile under-driven conical milling machine known for its efficient size reduction capabilities. Leveraging a gearbox-driven impeller rotating within a 60-degree screen, it ensures effective comminution by compressing and shearing materials, making it ideal for pharmaceutical, food, and chemical industries. With models catering from lab to high-capacity production, it supports tablet formulations, protein powders, and cannabinoid isolates, offering throughput up to 4000 kgs/hr. Its design integrates seamlessly with production lines, providing in-line feed and discharge. Built with 316L stainless steel, it complies with GMP and FDA regulations, ensuring corrosion resistance and product safety. Optimized for low heat and noise, it includes custom options like CIP systems and ATEX-rated components for explosive environments.
