A co-mill, short for conical mill, is a pharmaceutical milling machine used for size reduction and granulation of various pharmaceutical ingredients. Its distinctive conical shape allows for efficient milling within a chamber that gradually tapers towards the discharge port.

This equipment operates by feeding the material into the conical chamber, where it encounters rotating blades or impellers. These blades crush and grind the material against the chamber walls, reducing it to the desired particle size. The size of the particles can be controlled by adjusting the speed of the blades and the residence time within the mill.

Co-mills are versatile machines capable of handling a wide range of materials, including powders, granules, and even semi-solid materials. They are commonly used in pharmaceutical manufacturing processes such as dry milling, wet milling, granulation, and size separation.

One of the key advantages of co-mills is their ease of cleaning and maintenance. They are designed with detachable parts and smooth surfaces to facilitate thorough cleaning between batches, minimizing the risk of cross-contamination.

Available in various sizes and capacities, co-mills can be used for both laboratory-scale research and large-scale production. They are designed and manufactured to meet stringent regulatory standards, ensuring product quality and compliance with Good Manufacturing Practices (GMP) guidelines.
