Gyratory Crusher Operation
These will have to be removed or broken, after all, it can't be crushed if it can't get into the crusher. This large ore will slow things down greatly due to the delivery of new ore being suspended until the large ore is out of the way. Even If this large ore is small enough to make it into the crusher, production will still be slow.

For a screen deck to work properly every piece of ore must come into contact with the surface of the screen. To be sized the ore to have the opportunity of going through the screen mesh. As the tonnage is increased the area, on the screen deck that is available for the ore to come into contact with, decreases.
Ore Crushing
For some special purposes, roller crusher and hammer crusher can also be used. Ore fine crushing is a process of crushing ore blocks with a feeding particle size of 50–150 mm to 5–25 mm, and the maximum crushing ratio of fine crushing is about five. The main equipment suitable for fine crushing operations includes a fine crushing jaw ...
