Particle Size Reduction

Particle size reduction is an important step in manufacturing pharmaceuticals, nutraceuticals, cosmetics, food ingredients, and more. It can be referred to as milling, grinding, comminuting, or granulating, but ultimately, it's about ensuring that particles are of an appropriate, uniform size for the application at hand. It can be referred to as milling, grinding, granulating, or other names, but ultimately, it's about ensuring that particles are of an appropriate, uniform size for the application at hand.

After all, particle size can impact rates of dissolution or absorption, chemical reactions, and the physical characteristics of a finished product.

Particle size reduction equipment can be used to break apart clumps or agglomerates that may have developed during storage, transportation, or handling (often called deagglomeration) or to simply reduce the average size of particles in a wet or dry powder. 

Granumill options

Fluid Air GRANUMILL® milling systems can size reduce wet or dry powders in the range of 10 to 400 mesh (2000-27 microns). The systems are equipped with variable speed drives to permit low speed screening and high speed impacting with one milling system.

A typical Fluid Air milling system consists of an inlet, chamber with rotor, screen, and an outlet. The particle size distribution generated is dependent upon the speed of the rotor, rotor type, screen hole size and the feed rate of the product.

All of these parameters are critical and will affect the end particle distribution.
