What Is The Crushing Process
Crushing is the process of size reduction of ore. Size reduction process begins with usage of explosives at the area for production of ore. In later stages, the size reduction process performed with crushers before grinding in mills is called "crushing". Although there is no limit set, the downsizing process over 3 mm is considered as "crushing ...

Aggregate | Earth Sciences Museum
Aggregate materials are either used in their natural state or after crushing, washing, and sizing. The materials can be used loosely, or sand, gravel, and crushed stone can be combined with a binding media to form concrete, mortar or asphalt. The mining process begins with the removal of the overburden to reveal the materials underneath.

Crushing and Sieving
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.
