Cone Crushers — an Introduction

This section of the Aggregate Designs Corporation web site is intended to inform the reader about different aspects of cone crushers. They are sometimes called gyratory cone crushers. Cone crushers crush rock between two conical surfaces called the mantle (lower movable surface) and the concave liners above. These surfaces do the actual crushing and are constructed of high manganese steel. Cone crushers can be used in a primary crushing role but are typically seen more often in a secondary or tertiary position. There are two types of cone crushers with respect to the pay product size: stand head and fine head cone crushers. Fine head cone crushers have a reduced-size opening and so can't take as large of feed material but can produce a finer output product. Crushing action is achieved by the eccentric movement of the lower portion of the main shaft. The mantle is connected to this main shaft. The gyrating action of the main shaft causes the gaps between the mantle and liners to change dimension and perform the actual crushing.

Cone crusher working principle

A Gyratory Cone Crusher is one of the main types of primary crushers in a mine or ore processing plant. Gyratory cone crushers are designated in size either by the gape and mantle diameter or by the size of the receiving opening. Gyratory cone crushers can be used for primary or secondary crushing. The crushing action is caused by the closing of the gap between the mantle line (movable) mounted on the central vertical spindle and the concave liners (fixed) mounted on the main frame of the crusher. The gap is opened and closed by an eccentric on the bottom of the spindle that causes the central vertical spindle to gyrate. The vertical spindle is free to rotate around its own axis. The crusher illustrated is a short-shaft suspended spindle type, meaning that the main shaft is suspended at the top and that the eccentric is mounted above the gear. The short-shaft design has superceded the long-shaft design in which the eccentric is mounted below the gear.
