At the top of each of the three raises the ore passes through a crusher before it enters the raise proper and thence falls to a pan-feeder, which feeds the belt. The belt system, fed from the three raises, is 4,991 feet long and in nine sections, each driven by a 75-horsepower, 440- volt, A. C. motor. The belt is 7-ply and 30 inches wide.

Portable Crusher for Open Pit and Quarry Operations. The primary use of a portable crusher, i.e., a crusher mounted on crawlers or tires, in the rock and mining industries is to reduce costs by permitting the substitution of conveyor belt haulage for truck or track haulage.

The dominant haulage method in surface mining is mine trucks, typically large off-road trucks with haulage capacities of up to 360 tons (Fig. 11).Some open pits use railroad haulage or belt conveyors, the latter also frequently being used in conjunction with bucket–wheel excavators (Fig. 16), in operations where extremely large volumes of every soft rock (usually soil) are handled.
