In order to make use of the rocks or ores obtained through quarrying/explosion in the Mining and Construction sectors, the materials need to be crushed to reduce them to a smaller size. We call this process SIZE REDUCTION or CRUSHING.
The goals of the size reduction
1.) Obtaining the size or surface area required for the use of the ore or material.
2.) Allowing ease of transportation and storage.
3.) Separating the different minerals contained within the ore and to release them from one another
4.) Obtaining the size or surface area required for the enrichment stage.
In general, crushing is carried out in three stages, depending on the desired size of the material.
This is the first stage of the crushing process.This process can use jaw crusher. In general, the size of the feed material, which is between 800 and 1500 mm, is reduced to between 150 and 300 mm.
This is the third stage of crushing. The size, which is around 50–80 mm, of the ore or rock from the secondary crushing process is reduced to between 5 and 12 mm.
We call the machine that performs the CRUSHING process a CRUSHING MACHINE or CRUSHER.
