Particle Size Effects on Hydro-Cyclone Performance

The hydrocyclone has a very important roll in industrial separation. The consideration of its behavior is very important for design. In this investigation, behavior of water flow and particles trajectory inside a hydrocyclone has been considered by means of numerical and experimental methods, and results have been compared together. To have a numerical simulation, a CFD software was used, and f...

Image Analysis for Particle Size Distribution

Particle size distribution (PSD) affects properties of particulate materials and is used for denoting their quality and performance. Among many techniques available to measure PSD, many are quite often offline methods and are time consuming. Also methods like sieving involve, handling of the material physically and electromagnetically, which is healthy, if avoided for certain materials. Thus th...

Basic Principles of Particle Size Analysis

Imagine that I give you a matchbox and a ruler and ask you to tell me the size of it. You may reply saying that the matchbox is 20 x 10 x 5mm. You cannot correctly say "the matchbox is 20mm" as this is only one aspect of its size. So it is not possible for you to describe the 3-dimensional matchbox with one unique number. Obviously the situation is more difficult for a complex shape like a grai...

Successful Particle Size Analysis of Dry Powders

A correctly set up dry powder measurement using a laser diffraction particle size analyser is much easier to perform than measurement of wet suspensions. However, incorrect measurement set-up can lead to errors and inconsistencies. This article examines the key steps achieving successful dry to powder measurement. Issues examined include powder flowability and sampling, air pressure and sample ...
