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.

The products can be extracted immediately after the gyratory crusher as 0-32 mm or 0-63 mm fractions, if necessary; these materials are used when stability is needed for the given construction application. The tertiary stage produces fractions in sizes ranging from 0-2 mm to 16-32 mm. These products are used in asphalt and concrete.
