In this paper, a DEM model was applied to a copper mining gyratory crusher to perform a comprehensive analysis of the loads in the mantle, the crushing torque, and crushing power.

Failure analysis of eccentric bushings in large gyratory crusher

Shortly after the start-up of the loaded gyratory crusher, a severe failure issue occurred in the eccentric bushing of the crusher. Based on the analysis of working conditions and force, the failure mechanism of the eccentric bushing is studied in detail by combining macroscopic analysis, finite element analysis, scanning electron microscopy (SEM) and …

2. GYRATORY CRUSHERS

When the feed to a gyratory crusher is run-of-mine it is normally referred to as a primary crusher. Similar crushers that are used follow- ing these units are known as secondaries. Two different types of sec- ondary gyratories have been developed based on the crusher product requirements.

Working Principle of Crushers

In gyratory crushers the crushing process comprises reduction by compression between two confining faces and a subsequent freeing movement during which the material …

Gyratory and Cone Crusher

The gyratory crushers crush to reduce the size by a maximum of about one-tenth its size. Usually, metallurgical operations require greater size reduction; hence, the products from the primary crushers are conveyed to secondary or cone …

Primary Crusher vs. Secondary Crusher: Understanding Their …

The primary crusher is usually a jaw crusher or a gyratory crusher, which operates by compressing the material between two surfaces. The jaw crusher works by moving the material between a fixed and a moving plate. The moving plate applies force to the material, causing it to break down into smaller pieces.

Gyratory Crusher

Gyratory crusher is a crushing equipment that uses the gyratory motion of the crushing cone in the conical cavity inside the shell to extrude, bend, and impact materials, for …

Gyratory Crusher vs. Cone Crusher: What's the Difference?

A gyratory crusher is a type of crushing equipment that is used to break down larger stones and rocks into smaller pieces. It consists of a concave surface and a conical head, both of which are typically lined with manganese steel. The gyratory crusher operates by means of a gyrating mantle, which gyrates continuously against a stationary ...

Gyratory Crusher (Gyratory Crushers Explained)

Gyratory crushers typically crush to reduce the size of aggregate to a maximum of about one-tenth of its original size. Gyratory crushers are always installed vertically orientated. A gyratory crusher's size is classified by: Its gape and mantle diameter. The …

Crushing in Mineral Processing

Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4 :1 and 9 : 1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3 :1 to 10 :1.
