Crushing and Sieving

Crushing and Sieving. When a sample arrives it is first crushed and sieved. This is to obtain the correct grain size for the rest of the separation process. The ideal grain size is 0.25-0.50mm. There are two crushing machines available; a jaw-crusher and a disc-pulverizer. Samples are usually run through the jaw-crusher first, and then the ...

Particle-size distribution

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.

5 Size Reduction and Sieve Analysis

A crushing law proposed by Rittinger in 1867 states that the work required in crushing is proportional to the new surface created. This "law," which is really no more than a hypothesis, is equivalent to the statement that the crushing efficiency is constant and, for a given machine and feed material, is independent of the sizes of feed and product
