2. GYRATORY CRUSHERS - Metallurgist & Mineral Processing ...

A movable crushing surface called the mantle, also conical in shape, gyrates within the interior of the concave cone. As this is a gravity device the material flows from top to bottom. The gyratory crusher has been built in three types known respec- tively as the suspended-spindle, the supported-spindle and the fixed- spindle type.

Gyratory Crusher - Design of mantle and concaves ...

If you don't keep the crusher choke fed the mantle and concaves will wear to a point where the reduction profile is changed and thus causes higher power draw and lots of heat. It's the same when a "ducktail" is formed by not coke feeding or by having too many fines in the feed. The reduction profile is the key.

AMIT 135: Lesson 5 Crushing – Mining Mill Operator …

Gyratory Crushers Invented by Charles Brown in 1877 and developed by Gates in 1881; Gates Crusher. A conical element is supported in a flared shell or frame creating a chamber wide at the top and narrow at the bottom. The center element is caused to gyrate about its fulcrum point causing it to advance and retreat with relation to the shell.

Gyratory Crusher - an overview | ScienceDirect Topics

A gyratory crusher includes a solid cone set on a revolving shaft and placed within a hollow body, which has conical or vertical sloping sides. Material is crushed when the crushing surfaces approach each other and the crushed products fall through the discharging opening.
