Jan 16, 2013· The desired particle size depends on the solid-dosage requirements, notes Brian List, sales and marketing manager at the Jet Pulverizer Company, with typical API particle sizes in the 2-5 micrometer range The minimum particle size that can be obtained using a jet mill depends on the inner friability of the material, explains List.

May 01, 2010· Once it is determined that a particle size specification of pharmaceutical powder is needed, the next question is how to establish an appropriate particle size specification In many NDAs and ANDAs, it is found that the particle size specifications submitted are inadequate to control the PSDs of pharmaceutical powders.

Small Particles and Particle Size STUDY PLAY Why is particle size important? , the stuff into smaller stuff they can be cut or smashed the smaller particles filter out the bottom the faster the mill, the greater the force so get small particl , if too small can also cause problems so need to know size range.

The particle-size distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size Significant energy is usually required to disintegrate soil, etc particles into the PSD that is then called a grain size distribution.
