A crusher, also known as a stone crusher, is a machine that uses mechanical action to break large rocks, ores, or other raw materials into gravel or rock powder. ... Here is an introduction to the different types of crushers used at each stage and their characteristics. 1. Primary crushing equipment ... Gyratory Crusher.

Wearing parts in the gyratory crusher may be either chilled cast iron or manganese steel, depending on the character of the material to be crushed and the particular class of service for which the machine is intended. Standard crushers, in the small and medium sizes, are customarily fitted with chilled-iron head and concaves for crushing soft and medium limestone …

A primary gyratory crusher was required to crush iron ore at the rate of 3000 t/h. The largest size of the run-of-mine ore was 1000 mm. The required product size was less than 162 mm. Manufacturer's data indicated that the nearest size of gyratory crusher would be 1370 mm × 1880 mm with a cone angle of 18°.

Diagram of a gyratory crusher [image: 135-5-16)] Gyratory Crushing Action. Designs of the breaking faces vary with manufacturer.

A gyratory crusher was patented by Philetus W. Gates in 1881. Thomas A. Edison also designed a rock crusher to use in his own mining operation. Edison's design used giant rolls to function as a primary 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 …

There are several types of primary crushers, including jaw crushers, gyratory crushers, and impact crushers. Jaw crushers are commonly used in the aggregates industry and are designed to handle large, blocky …

Comminution by gyratory crusher is the first stage in the size reduction operation in mineral processing.
