Section snippets Gyratory crusher importance. Gyratory crushers are the usual choice for primary crushing in high tonnage open-pit operations. This is especially true when the ore to be processed is hard and abrasive and the downstream phase requires relatively coarse material such as grinding circuits equipped with SAG mills (Major, 2002).

A gyratory crusher and system for determining a close-side setting or an open- side setting is provided including a point cloud generator mounted proximate the crusher; a laser emitter mounted to mark the first trace on the mantle at a predetermined position of the gap; a drone; a camera mounted on the drone to capture a series of …

5.1. 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°.

Crusher Close Side Settings. When it is necessary, or desirable, to operate a gyratory crusher at discharge settings below the minimum standard, the safe procedure is to fit the machine with a reduced throw eccentric. The crusher manufacturer will be able to advise the operator about these special throws for machines of his make.

Gyratory crushers were invented by Charles Brown in 1877 and developed by Gates around 1881 and were referred to as a Gates crusher [1]. The smaller form is described as a cone crusher. The larger crushers are normally known as primary crushers as they are …

The majority of gyratory crushers are used as primaries, i.e. they receive the initial feed from the mine or quarry. The same type of crusher with chamber modifications is used as a secondary crusher, particularly when following a large primary crusher. The fine-reduction gyratory crusher can also be used for tertiary crushing.

The invention relates to a gyratory crusher in which a piston surrounds a wabbler shaft or eccentric sleeve and the radial forces of the spindle shaft are transmitted to the frame of the crusher through the piston. ...

A primary crusher is designed to receive run-on-mine (ROM) rocks directly from the mines. 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:

ratory crusher, and short-shaft gearless gyratory crusher. The gyratory crusher, whether used as a primary or secondary. is essentially a gravity-type machine. Material flows vertically from top to bottom. It receives a large coarse feed, usually run-of-mine, and its product normally requires additional crushing before produc- ing the final ...
