Micronization Process

Particle size reduction is achieved through the use of fluid energy jet mills. The material is drawn into a confined, circular chamber by way of pressurized nitrogen gas or compressed air. The powder gets suspended in a high velocity fluid stream in the milling chamber. The mill operates on the principle of impact and attrition due to the high velocity collisions between particles suspended within the nitrogen gas or compressed air stream, causing them to breakdown into smaller particles. Centrifugal force causes large, heavy particles to separate from smaller and lighter particles. The smaller particles are carried in the fluid stream towards the center of the milling chamber, where they are discharged into a collection bag. Larger particles remain in the milling chamber where they recirculate, causing them to breakdown. Operational parameters are monitored throughout the process and are documented in the batch record.

In-process samples of the micronized material are taken for particle size analysis. Based on the particle size results the milling parameters will be adjusted to achieve the established particle size specification. Upon completion of this process, the material is released as per specification.
