Crushers
This can easily be broken down in to three sections, pre-crushing, crushing, and post crushing. Pre-crushing is the movement of material through the grizzly, down the ore pass, and finally into the crusher itself. The crushing section is the ores movement through the crusher. This will vary, of course, depending on which crusher is utilized.
