For A Given Bulk Solid How Can The Particle Size Distribution Be Determined? |
|
Answer» In order to determine the particle size distribution the simplest method is to make use of a sieve stack. In this method a stack is created of with different mesh sizes at each stack level. The structure is such that the biggest mesh size is at the top and the SMALLEST at the bottom. Once this setup is created the before beginning the weight and other values of the solid is noted down. Once this is done the solid is placed at the topmost cylinder and the entire setup is exposed to a combination of VERTICAL and horizontal MOVEMENTS. This will make the solid pass through different mesh sizes in the process separating the different particles ACCORDING to their sizes. There are other more advanced methods of determining the particle size distribution as well such as video imaging and laser DIFFRACTION as well.
