![]() ![]() Size of particle system or particle diameter distribution means the regularity of the sizes of all the particles. In case all the particles making up particle system have same or almost same particle size we call such particle system Monodisperse however in case the particle system is made up of particles different in size, we call it Polydisperse. Particle system is made up of many particles.When we speak size, we mean size of a single particle when we say particle size distribution, we mean size distribution of particle system.Dn50 is known as number median, it physically represents that each number of particles greater or smaller than such value takes account of 50% of the total particles number.ĪS-300 Hall Flowmeter︱Flow Meter Funnel︱Metal Powder Flow Rate︱Apparent Density︱Carney︱Manufacturer Dv50 is also known as volume median or volume average particle size, it physically represents that each volume of particles greater or smaller than such value takes account of 50% of the total particles volume. D50 is also divided into Dv50, Dw50 and Dn50, Dv50 means volume D50, whereas Dw50 is mass D50 and Dn50 is number D50. In the cumulative particle size distribution graph(curve), the ordinate represents the cumulative particle size distribution 0% to 100%, the abscissa represents the particle size, now find the cumulative distribution 50% on the ordinate, its corresponding particle size value in ordinate is D50. When we speak of D50 we mean cumulative particle size distribution D50.D50 is also named x50 or Dx50 particle size according to some ISO standards or user’s tradition.Function: particle distribution functionally including R-R distribution and normal distribution Figure: particle distribution by histogram and curves, etc. Usually we use following three methods to characterize particle size distribution such as Table: percentage of particles from the total within a size range it includes differential distribution and cumulative distribution.A particle size analyzer is being used to measure particle size of particles. Particle size distribution is the number of particles that fall into each of the various size ranges given as a percentage of the total number of all sizes in the sample of interest. ![]()
