The walls of the gyratory crusher's hopper are lined with "V-shaped" pieces, the mantle and the concave, like a jaw crusher but shaped like a cone. The ore is discharged through the smaller bottom output hole of the cone. While the cone does not move, an interior crushing movement is created by a revolving shaft on a vertical rod.
The first of these is the so-called Rittinger's law, which is variously stated as follows: "The work of crushing is proportional to the reduction in diameter."—R. H.
