Nevertheless, gyratory crushers are usually more expensive, need more intricate foundation and have higher operating and maintenance costs as compared to jaw crushers. The decision of a jaw crusher or a gyratory crusher is based on, for instance, the required output size, production capacity, and the available budget.

Above figure shows sectional view of a typical gyratory crusher. Essentially, a gyratory crusher consists of a heavy cast-iron, or steel, shell/frame which includes in its lower part an actuating mechanism (eccentric and driving gears), and in its upper part a cone shaped crushing chamber, lined with wear resisting plates (concaves ...
Therefore, the working process of the gyratory crusher is taken as the specific analysis object, in this paper, the gyratory crusher performances, including the productivity, crushing force distribution, and particle size distribution, are explored by the DEM simulation. Furthermore, the influence of the mantle shaft angle, the concave angle ...
With crushing chambers of varying designs, these machines have either a high crushing ratio for preparing raw materials for secondary crushing or a low crushing ratio for …
The working process of the gyratory crusher is used as a specific analytical target in this paper, and the performances of the gyratory crusher, including productivity, mass percentage of effective particles, and crushing force, are explored through DEM simulation. Furthermore, the impact of different positions of concave curve control points ...

In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear …
The crushing process is divided into three main stages: primary, secondary, and tertiary. In the primary stage, heavy machinery is used to reduce the size of the material coming from the mines (blocks from 1000 to 500 mm to 300-100 mm). ... Unlike the jaw crusher, the gyratory crusher must work with the crushing chamber full and …
CG800i Gyratory crusher brochure Capacity (by hour) 2,700 - 6,000 mtph (2,980 - 6,610 stph) Feed opening 1,525.0 mm (60.0 in.) ... and our vendors use cookies (and similar technologies) to …
When the gyratory crusher is in working condition, the driving motor drives the mantle around the top suspension point through the bevel gear transmission system to perform rotary pendulum movement. As the mantle approaches the concavity, the ore between the mantle and the concavity is crushed under the action of squeezing pressure.
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.
Gyratory Crusher Operation. Crusher are used to reduce the ore in size, the purpose and the responsibility of the crusher operator is to operate that crusher in such a manner as to ensure that every …
Gyratory crusher comes in three basic types: fixed shaft type, slant discharge type, and central discharge type. The central discharge type (Fig. 1) is quite common.Gyratory crusher achieves discharge port adjustment and overload protection in two ways: (1) In a mechanical crusher that uses mechanical power, the upper end of …
The gyratory crusher is one of the most important mineral processing assets in the comminution circuit, and its production performance directly impacts the circuit throughput. Due to its higher energy utilisation rate for rock breakage than semi-autogenous (SAG/AG) milling, it is a common practice in operations to promote and optimise primary …
Gyratory Crushers. Gyratory crushers feature a conical head and concave surface (often lined with manganese steel) and break apart material by compression through what is known as eccentric movement. Like jaw crushers, gyratory crushers are often utilized in primary crushing stations, though they may sometimes be used as secondary crushers, …
That means higher capacities, lower power requirements, and more evenly distributed wear patterns on all crusher wear parts for lower operating cost per ton. SUPERIOR® primary gyratory crushers are suitable for: The most demanding crushing applications; Stationary and semi-mobile applications; The hardest rock and ores; Surface and underground ...
X series gyratory crusher is a new generation of primary crushing equipment developed by our group for ultra-large mining and quarrying projects. It integrates mechanical, hydraulic, electrical, automation, intelligent control and other technologies,the crushing process is carried out continuously along the ring-shaped crushing cavity, which ...
How does a gyratory crusher work? The rotary crusher operates by the rotary motion generated by the eccentric arrangement of the main shaft.
