Conical mill for particle size reduction

Achieve precise particle size control and reduce thermal stress on materials with this robust milling solution, ideal for high-capacity powder processing and scaling production efficiency.

Achieves Efficient Particle Size Reduction

The Uni-Mill B-Series from Hanningfield is an over-driven conical milling solution that excels in efficient particle size reduction across pharmaceutical, nutraceutical, and chemical industries. Utilizing a belt-driven impeller inside a 60º inclusive screen, it ensures precise comminution through compression and shearing. This conical mill accommodates both dry and wet milling, supporting diverse applications such as powder processing and oral solid dosage production. Capable of achieving particle sizes as low as 150 microns, the Uni-Mill models offer varying throughputs—up to 7200 kgs/hr. Designed for seamless integration into production lines, the mill can be customized with options like nitrogen purging and temperature monitoring. Constructed with 316L stainless steel contact parts, and FDA-compliant seals, it complies with stringent industry standards, including ATEX for explosive environments. With customization available for inlet/outlet configurations, it supports efficient CIP systems for easy and contamination-free cleaning, backed by engineering support for tailored solutions.

Benefits

  • Enhances production efficiency by achieving precise particle size control with minimal heat generation.
  • Operates quietly due to belt-driven design, reducing workplace noise levels.
  • Ensures compatibility with stringent regulatory standards by using FDA-compliant materials and offering ATEX certification.
