the flow of the primary crushing process

    Secondary Crushing Stage The simplest form of secondary crushing stage involves a single crusher, taking its feed by gravity flow direct from the primary with no interposed scalping separation. This is tantamount to making the over-all reduction in one machine, except of course that there will always be a certain amount of surge capacity between the two crushers.

    The flow diagram is shown in Figure 8.2. ... The classic crushing circuit prepares primary crushed ore for secondary milling, or heap leaching, by using two stages of crushing. Most typically, stockpiled primary crusher product is reclaimed and fed to a secondary crusher. In turn, the product of a secondary crusher operating in open circuit is screened, with oversize fed to a tertiary crushing ...

    With our second schematic, the flow sheet is practically the same. The ore is a little harder and the sizing more critical however, this means the positioning of the equipment has to change a little.
