Crushing and Sieving - Purdue University
Crush the sample and pass it through the sieves. Put a magazine or piece of wood over the top of the crusher so that sample material does not fly out and hit you. 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.
Crushing and Sieving - physics.purdue.edu
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.

Sieving - Definition & Process, Sieving Method Of,
18-06-2016· The sample is subjected to horizontal or vertical motion during sieving according to the method chosen. This causes a relative movement between the particles and the sieve; the individual particles either pass through the sieve mesh, or are retained on the sieve surface depending on their size. What is the benefits of Sieving?

Aggregate Crushing Value Test | Crushing Value Of,
The crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the 2.36m IS sieve is known as Aggregate crushing value.. In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the “ten percent fines value”
