Cone Crusher Machine Structure And Introduction

Cone crusher comes in different sizes depending on desired production output rates.  This size also determines the maximum diameter of input material the cone crusher can handle.
Fine vs Standard Head Size
This has to do with the clearance built into the mantle in terms of its distance from the liners.  Fine heads have less clearance and can produce a finer output product while standard heads allow for a larger output product.
Remote Adjustment in Cone Crusher Machine
Remote adjusters in the stone crusher are a quite valuable feature, often adding $100,000 to $150,000 to the price of a unit.  They allow for "on-the-fly" adjustment of the mantle/liner clearance distance.  If you don't have this feature you must stop the crusher and adjust it with wrenches.  Some manufacturers included this as a standard feature.
Cone Crusher Illustrations
A Gyratory Cone Crusher is one of the main types of primary stone crusher in a mine or ore processing plant just like the impact crusher. 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 The short-shaft design has superceded the long-shaft design in which the eccentric is mounted below the gear.
