Primary crushing brings run-of-mine ore down to a maximum size of the order 4″ to 6″ in average diameter; secondary crushing receives feed at −6″ and reduces it to below "Dry" crushing includes work on ore as mined, which may be somewhat moist when delivered. It is succeeded by comminution in water, arbitrarily called "grinding".
The primary crushing process of an iron ore mine involves the use of a large jaw crusher or a gyratory crusher, which are designed to handle large rocks and ores. The crushing process begins with the ore being fed into the crusher, which uses a set of jaws or a cone to break down the material into smaller pieces.

Activities involved in finding, mining and processing iron ore at our Pilbara operations have been simplified in the following diagram. Rio Tinto operates 11 iron ore mines in the Pilbara and the specific sequence of activities varies from mine to mine. Excellence in planning, scheduling and quality control are fundamental to the process.
The list of commodities is extensive, although the relative proportions mined underground and on the surface vary from mineral to mineral. Massive tonnages of hard coal and lignite are also produced from surface mines, although the terminology used – open cast or open cut, rather than open-pit – indicates that the technology and …
The term "primary crusher," by definition, might embrace any type and size of crushing machine. ... For such rock or ore our choice of a primary crusher is restricted to the gyratory and jaw types except, again, for the occasional "specialty" application where economy in maintenance may be saced for other considerations such as ...
It mainly includes crushing process control, crushing appliance fault diagnosis, and automatic distributing control. Crushing Process Control. To ensure the continuous, stable, and safe operation of the ore crushing production process, it is necessary to monitor the running state and parameters of key equipment (such as …
