A gyratory crushing apparatus for frangible or friable material comprises: a bowl having a chamber for receiving the material and a discharge opening disposed at the base with a central axis and a gyratory axis extending at an angle to the central axis; a crushing head and a drive assembly. The discharge opening defines a throat with a circumferential wall …
Unlike jaw and gyratory crushers, where reduction is progressive by repeated nipping action as the material passes down to the discharge, the crushing process in rolls is one of single pressure. ... Unless very large diameter rolls are used, the angle of nip limits the reduction ratio of the crusher, and since reduction ratios greater than 4:1 ...
The below image shows a sectional view of a typical gyratory crusher. This type of machine is, by virtue of chronological priority, known as the "standard" ... The contour of the crushing chamber at the bottom is designed to afford various initial settings without changing the angle of the nip. This is accomplished by installing lower tier ...

The cone crusher is a modified gyratory crusher, and accordingly many of the same terms including gape, set, and throw, apply. The essential difference is that the shorter spindle of the cone crusher is not suspended, as in the gyratory, but is supported in a curved, universal bearing below the gyratory head or cone (Figure 6.8).Major suppliers …

Abstract. Detail descriptions of designs are given of large gyratory crushers that are used as primary crushers to reduce the size of large run-of-mine ore pieces to acceptable sizes. Descriptions of secondary and tertiary cone crushers that usually follow gyratory crushers are also given in detail. The practical method of operation of each ...
Higher reduction ratio: Gyratory cone crushers are capable of producing a finer product than jaw crushers, due to their larger size and higher horsepower. Uniform particle size distribution: The crushing chamber of a gyratory cone crusher is designed in such a way that the particles are subjected to a uniform force throughout the crushing …
a is the nip angle; k is a material factor, 1.5 to 2.0 (includes your epsilon param) ... The tables also show that for a comparable maximum size of feed and setting, a gyratory crusher has a much greater capacity than a jaw crusher. The gyratory crusher obtains this advantage only at the cost of greater power to drive the crusher.
