Get Priced 50 is the median particle size for a fertilizer sample or load and the most common metric to report particle size. Units are usually reported in millimeters by most fertilizer manufacturers. SGN (Size Guide Number) values report on the average (not median) particle size multiplied by 100. For example, a fertilizer with an average particle size of mm equates to a SGN = 150.

Get PriceJan 03, 2012· Many types of colloidal particles possess a core–shell morphology. In this Article, we show that, if the core and shell densities differ, this morphology leads to an inherent density distribution for particles of finite polydispersity. If the shell is denser than the core, this density distribution implies an artificial narrowing of the particle size distribution as determined by disk ...
