However, the primary crushing and transportation of ore to the surface is often the factor that determines the mine?s capacity. The required capacity defines the size and type of crushing equipment and also the number of parallel crushers or plants required to meet the mine?s production rate.

The product size from a primary crusher is limited by the possible reduction ratio, which normally is around 10:1. The feed size to a primary crusher from the mines could be 1–1.5 m; thus, the maximum product size possible is 10–15 cm which is normally too large for down stream processing for mineral liberation. Hence, secondary and ...

We reasoned that a primary stibinide complex of uranium would require a sterically demanding R-group to provide kinetic stabilisation of any U−Sb bond, and began by examining protonolysis reactions as a potential route to prepare U−Sb linkages.

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".

Mine haul-truck capacity is an important factor at primary crusher installations, because it is cost-effective to integrate truck cycle time at the crusher station with mine/shovel operations. If a primary crusher dump pocket is undersized and unable to handle the mine's trucks, then operators must slowly meter the ore into the receiving hopper.

Crushing Uranium Ore. Depending upon ore shipment schedules, it is desirable to operate the crushing and sampling sections on a 7½ hour per day basis. Ore is delivered to the receiving hopper, which is provided with a grizzly. Feed to the primary Jaw Crusher is metered by a Apron Ore Feeder which discharges over a grizzly.
