The primary rock breaker most commonly used in large plants is the gyratory crusher, of which a typical section is shown in Fig. 5. It consists essentially of a gyrating crushing head (521) working inside a crushing bowl (522) which is fixed to the frame (501). The crushing head is carried on a short solid main shaft (515…See more on 911metallurgist

The angle of nip in gyratory crushers has definite limitations. In the older straight element crushing chamber, the angle ranges from 20" to 24". On large primary crushers, using curved or nonchoking concaves and where gravity is of marked aid to nip with the large pieces at the mouth. the angle runs from 25" to 30°.
Gyratory Crushers Gyratory crusher is generally used as a primary crusher. The crusher is popular due to its high throughput capacity and the large sized opening. The crusher is well suited for handling direct feed from haul/dump trucks. The gyratory crusher is mainly used in rock that is abrasive and/or has high compressive strength.
Jaw crushers, gyratory crushers and cone crushers operate according to the compression principle. Impact crushers, in turn, utilize the impact principle. Another way to classify the equipment is …
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 ...
1) Working Principle. The crushing work of the jaw crusher is carried out by two crushing surfaces, which are crushed by the rapid collision of the intelligible tooth plates. The ore enters the crushing cavity from the upper feeding port. When the movable tooth plate advances forward, the ore is crushed.

The cone crusher working principle involves the eccentric motion of the main shaft. This motion is created by the rotation of the main shaft, which is supported by a bearing located at the top of the machine. As the main shaft rotates, it causes the mantle to move back and forth against the concave, crushing the rocks and ores between them.

Jaw Crushers; Cone Crushers; Typically, the initial crushing stage is completed using either gyratory crushers or jaw crushers. It is often the case that there will be only one crusher installed, and this will be referred to as the primary crusher. Cone crushers are more often used for 2nd, 3rd & 4th stage crushing steps (although not always).
The working principle of tertiary crushers varies depending on the type of crusher, but generally, they work by applying pressure to the material through compression or impact. VSI crushers work by throwing the material against a hard surface to produce a cubical-shaped product. Cone crushers and roll crushers work by compressing the …
Cone crusher and gyratory crusher work on the same principle. Both have the same operation. If cone crusher differs then it is only from crushing chamber. Cone crusher has a less steep crushing chamber and more parallel zone between crushing zones. It breaks the rocks by squeezing it between the gyrating spindles.

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°.
The jaw crushers, cone crushers are basically based on the principle of extrusion crushing, while impact crushers use the principle of impact "free" crushing to crush the ore. As shown in Figure 2-4-4, when the ore enters the crusher, it is mainly impacted by the high-speed rotating percussion plate, and the ore is selectively crushed …

Jaw crushers are used as primary crushers, or the first step in the process of reducing rock. They crush primarily by using compression. The rock is dropped between two rigid pieces of metal, one of which then moves inwards towards the rock, and the rock is crushed because it has a lower breaking point than the opposing metal piece.
The cone crusher has a high reduction ratio, ensuring efficient material crushing. Discharge: This is the final stage of the crushing process. When the material is crushed into the preferred size, it exits the cone crusher through an opening at the bottom. The entrance is located between the mantle and the bowl liner.
