Sieve the sample to remove the grain size you want. Crushing the sample again will crush the grain size you want. This will reduce the amount of the grain size fraction you want. Reset the crusher jaws so that they are two or three millimeters apart. Collect the material from the upper sieve and crush it again, then pass it through the sieves.

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 ...
