Large receiving opening per dollar of investment. Shape of receiving opening favourable for blocky feed. This, plus point 1, give the jaw a definite advantage over the gyratory, except in the very large sizes, for handling rock of massive formation. The jaw crusher is more easily adjusted, to compensate for wear of liners.

Using quality rock crushers in your gold mining operation can bring a range of benefits, including increased efficiency and reduced operating costs. By investing in quality equipment, you can: Increase your production rate and throughput. Reduce your maintenance costs. Improve the quality of your final product.
The gyratory crusher is located at the bottom of the rock box. Material is crushed between the rotating crushing cone and the fixed, tapered crushing throat. The Rockbreaker is mounted in-line with the upper support of the rotating cone, called the spider. This provides superior maneuverability of the Rockbreaker within the gyratory throat.
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 ...

The common jaw crusher has single toggle type and double toggle type, the former one also called as simple swing crusher, the latter one is called as complex swing crusher. 3. Gyratory crusher The gyratory crusher is a large scale crushing machine which uses the gyratory movement of the crushing cone in the crushing cavity to extrude, squeeze ...
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.
To study and optimize the gyratory crusher performance, taking the process of crushing iron ore by the gyratory crusher as the specific analysis object in this paper. …
Industrial crushers reduce large rocks, ore or waste materials to smaller sizes by impact or pressure to fracture or deform the material. During the primary crushing operation, boulder size feeds from 20 to 100 in. are reduced to secondary crusher sizes of 1 to 20 in. or mill feed size of .5 to 3 in. ... Gyratory crushers are very similar to ...

Optimizing capacity and economy in jaw and gyratory crushers. Eng. Min. J. 1984, 185, 69–71. [Google Scholar] Rose, H.E.; English, J.E. Theoretical analysis of …
CONE CRUSHER. Cone crushers are similar to gyratory crushers in that they have a mantle that rotates within a bowl, but the chamber is not as steep. They are compression crushers that generally provide reduction ratios of 6-to-1 to 4-to-1. Cone crushers are used in secondary, tertiary and quaternary stages.
The jaw crusher 2. The gyratory and 3. The cone crusher. Crusher Sizing • Jaw crushers are sized on the basis of the maximum particle size to be crushed or the tonnage rate to be crushed. • Maximum particle size should not exceed 80% of the gape. • For example, a 400- by 600-mm crusher will accept a maximum lump size of 400 by 0.8 = 320mm.
In terms of design and construction, gyratory crushers and cone crushers have distinct differences. A gyratory crusher has a mantle that rotates within a concave bowl, while a cone crusher has a mantle that rotates within a bowl-shaped concave. This design allows for a larger feed size and a higher capacity for both types of crushers, but ...
A crusher is a machine designed to reduce the size of Run of Mine (ROM) large rocks to smaller rocks, gravel, sand, or rock dust; this is essential for efficient transport of the ore via conveyors etc. Crushing is the first of …
In the Gyratory all the movement is in the bottom of the crusher mantle. This is due to the angle that the main shaft is on. The greater angle of the cone crusher puts the pivot point below the distributor plate. While the pivot point for the gyratory crusher is at the spider cap. This difference in the pattern of gyration has a purpose.
From Allis-Chalmers' Superior Primary and Secondary Crushers. ° Actual required depends on stone hardness, reduction ratio, and so on. If a 60-in. gyratory crusher is to process material from a quarry where a shovel loads the raw material, the shovel would probably have to have a dipper capacity of at least 5 cu yd to be compatible.
Gyratory and jaw type gyratory crushers are more broadly an integral part of semi-mobile and stationary processing plants used for primary crushing of bulk materials in ore mines and the natural ...

The gyratory crusher has no rival in large plants with capacities starting from 1200 t/h and above. To have a feed opening corresponding to that of a jaw crusher, the primary gyratory crusher must be much taller and heavier. Also, primary gyratories require quite a massive foundation. Primary crushing with impact crushers
Compression crushers – which squeeze the material until it breaks. Impact crushers – which use the principle of rapid impact to shatter material. A ttrition crushers – which use both impact and grinding to shear material. Jaw crushers, cone crushers, gyratory crushers and roll crushers all operate on the compression principle.
Many small process plants consisted of one crusher, either jaw or gyratory rock crushers, one elevator and one screen. Recrushing, if done, was taken care of by the same machine handling the primary break. The single crusher, when of the gyratory type, might be any size from the No. 2 (6″ opening) to the No. 6 with 12-in. opening.
