Gyratory Crusher

Stone crusher machine divides into a mining crusher and a medical crusher. The mining crusher equipment divides into jaw crusher, gyratory crusher, impact crusher, cone crusher, hammer crushers, roller crushing, mobile crusher, etc. according to the principle of crushing. Jaw crusher for sale

What Gyratory Crusher

Gyratory crusher is a new type of crusher which can replace fine jaw crusher or cone crusher. The gyratory crushing equipment has a bright future in the mineral processing market. Its working part is a high-speed rotary crushing roller, which is coupled with a pair of curved crushing plates arranged symmetrically on the left and the right to form two optimal crushing cavities for the pliers. Under the action of the eccentricity of the main shaft, the crushing roller makes a transverse rotary motion. And make it produce strong cyclic extrusion pressure, continuous progressive on the two crushing cavities of the material alternately broken. Then the product from the two discharge mouth constantly discharge.

Crusher Working Principle

The primary gyratory crusher breaks the material by feeding mouth into the two rollers between the extrusion crushing, finished materials naturally fall. In case of too hard or can not be broken, the roller crusher by hydraulic cylinder or the role of the spring can automatically retreat. So that the gap between the rollers increase, too hard or can not break down, so as to protect the machine from damage. The opposite two rollers have a certain gap, change the gap, you can control the product maximum discharge granularity. Rotary crusher is the use of a pair of opposite rotation of the round roll. Four-roll crusher is the use of two pairs of opposite rotation of the round roll crushing operations.

JXSC tooth roller crusher mainly uses the special wear-resistant tooth roller high speed rotation to crack the material (the traditional tooth roller crusher uses the low speed extrusion crushing) , has formed the high productivity mechanism. The roller crusher with saw teeth on the surface of both rollers mainly plays the role of cracking and tearing, and also has the role of crushing, grinding and crushing. The broken teeth arranges in a spiral shape. The small particles in the feed are easily discharged through the gap between the broken rollers. The big pieces are broken by the shearing and tensile force of the teeth. The situation that the material is broken without control in the traditional crusher is improved.

Gyratory Crusher Working Principle

Crusher Machine Advantage

The good effect of fine crushing
1. There are cracks and other weak spots or defects in almost any particle. The double-cavity gyratory crushing, because of the multi-directional pressure on the material, under the interaction of multi-layer material, makes the material easier to be broken from the defect. Then it can obtain high crushing rate and produce more fine-grained products.
2. Due to Lamination crushing, even with a larger outlet, a finer product and a finer product size distribution can be obtained.
3. The high-frequency swing crushing roller can break the material more times than the traditional crusher in the crushing chamber, so the size of the discharging material is a greatly reduce.
The production practice shows that when the size of the feed is 80 mm, the content of 12 mm can reach 80 %, and the content of 6 mm can reach 50%.

Large processing capacity

1. Double-chamber gyratory crusher is a crusher machine that continues working with a double-chamber. The crusher equipment changes the discontinuous working mode of single chamber of jaw crusher.
2. The characterize is that producing more fine products under the condition of larger discharge port. Under the premise of ensuring fine products, the larger discharge port can obviously have more processing capacity.

Small work vibration
Gyratory crusher has no supporting structure of the elbow plate. The crushing roller works in a balanced rotary state. So the vibration is small and the noise is low. It can work smoothly on the steel frame without foundation.

Significant energy-saving effect

1. When double cavity rotary crusher machine crushing materials, the roller swing movement. The crushing force mainly occurs near the eccentric position of the crushing roller, forming high power density crushing. Then forming the crushing process with the circular movement of the eccentric position of the crushing roller. Because the crushing force concentrates on a small amount of material in a section of the crushing chamber, the crushing force uses in the operation is smaller and the energy utilization rate is high. Therefore, it has obvious energy-saving effect.
2. The crushing machine continuous working, which can make full use of the output energy of the driving motor. And it can make use of the strong kinetic energy of debris splashing produced in the process of rock crushing to carry out the re-crushing of the adjacent rocks. Repurposing the secondary energy.
3. As fully utilize the energy, the production practice has proved that the electricity consumption per ton of ore processing is generally 0.5 degrees.

Easy to maintenance, low cost

1. The double chamber rotary crusher works smoothly on the steel frame without foundation. Then civil construction is easier and installation is more convenient.
2. The crusher machine parts are all used expansion sleeve connection. So it is very convenient to disassemble and assemble, repeated disassembly will not affect the assembly accuracy of the machine.
3. Easy adjustment of discharge opening and simple structure.
4. Only use grease lubrication, management, and maintenance of convenient, low cost.

Gyratory Crusher VS Cone Crusher

1. The two cone shapes of the gyratory crusher are steeply inclined. The movable cone is upright, and the fixed cone is an inverted truncated cone which in order to increase the need for feeding ore. Nevertheless, cone crusher has two cone shapes, which are gently inclined, vertical frustum cone. There is a certain length of parallel ore crushing area (parallel belt) between the two cones which in order to control the requirement of mineral product granularity. Because of the medium and fine crusher, and coarse crusher different. It is to crush product quality and production capacity as the primary consideration.

2. The movable cone of gyratory crushers suspends from a beam at the upper part of the machine. The cone crusher supporters on a spherical bearing.

3. The gyratory rock crusher uses the dry type dust-proof device, and the cone stone crusher uses the water-sealed dust-proof device.

4. The gyratory stone crusher changes the size of the ore discharge port is using to adjust the rise or fall of movable cone. Cone crushers adjust the height of the fixed cone to realize the adjust of the width of the ore discharge mouth.
