Purdue University :: 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 pulverizer.
