Gyratory Crusher and Cone Crusher

The gyratory crusher is so similar to the cone crusher, is it the same kind of crusher? Friends who have seen the internal structure diagram of the gyratory crusher will definitely feel very similar to the cone crusher. They do have a lot in common in terms of crushing principle and internal structure. So what is the difference between cone crusher and gyratory crusher? The SBM editor will take you to compare the crushing cavity type, the moving cone suspension method, the discharge port adjustment, the dust prevention measures and the application.

1. The shape comparison of the crushing cavity

The two cones of the gyratory crusher are steeply inclined. The moving cone in the crushing chamber is upright and the fixed cone is an inverted truncated cone (mainly to meet the requirements of the feed particle size). The material can be vertically oriented by its own weight. Discharge freely.

Both cones of the cone crusher are gently inclined upright truncated cones, and in order to control the granularity of the discharged products, a section of parallel crushing area is set at the lower part of the crushing chamber, which results in different shapes of the crushing chambers.

2. Comparison of the suspension method of the moving cone

The moving cone of the gyratory crusher is suspended on the beam of the frame; the moving cone of the cone crusher is supported by spherical bearings.

Cone Crusher

It is emphasized here that the bowl cone with broken spring cone carries the moving cone and the main shaft (the moving cone and the main shaft are combined together), and the bottom is installed on the base through the bowl-shaped shaft bracket, so it is said that the base passes through the bowl-shaped shaft To carry weight. The bowl-shaped pedestal is a key component that carries weight.

The spherical tile of the multi-cylinder hydraulic cone crusher is at the top of the main shaft, which only carries the moving cone, and the lower end of the main shaft is directly installed on the machine body. Therefore, for the multi-cylinder hydraulic cone crusher, the main bearing weight is the main shaft and the machine base, and its bearing capacity comes from the main shaft strength and the base.

The main shaft of single-cylinder hydraulic cone crusher is floating type, supported at both ends. In addition to the lower end of the moving cone main shaft supported on the base, the upper end is also fixed in the shaft sleeve in the middle of the upper beam of the upper frame body, and the shaft sleeve is located exactly at the theoretical suspension point where the moving cone rotates.

3. Comparison of dustproof devices

The gyratory crusher generally uses a dry dustproof device, while the cone crusher usually uses a water seal dustproof device.

Spring cone crusher generally adopts dry oil seal dustproof, multi-cylinder adopts positive pressure dustproof and non-contact labyrinth seal to effectively prevent dust from contaminating lubricating oil, damaging bearings, and prolonging the service life of lubricating oil and equipment.

4. Comparison of adjustment methods of discharge opening

The gyratory crusher uses the lifting of the moving cone to adjust the width of the discharge port.

Springs (fixed pulleys or hydraulic pushers) and multi-cylinder cone crushers (hydraulic pushers or hydraulic motors) use fixed cone lifts to adjust the width of the discharge port. When adjusting the discharge port, first release the pressure of the locking cylinder, and then turn the adjustment ring clockwise or counterclockwise to raise or lower the fixed cone, so as to achieve the purpose of adjusting the discharge port.

The single-cylinder cone crusher pushes the main shaft and the moving cone up or down by the hydraulic cylinder placed at the bottom of the center of the base to achieve the purpose of increasing or decreasing the discharge port.

5. Comparison of application scope

Gyratory breaking is a large-scale crushing machine that crushes ore or rock of various hardnesses by using the gyroscopic movement of the crushing cone in the cone cavity of the shell to squeeze, split, and bend the materials.

Cone crushing is also suitable for the crushing of materials with higher hardness. It is generally used as a second-breaking equipment in the production line. There are short head type, standard type and medium type. The general standard type is used in medium crushing. Type is suitable for fine crushing.

In addition to the shape and crushing principle, the gyratory crusher and the hydraulic cone crusher have similarities in the discharge port adjustment device and the moving cone support method. Therefore, some say that the gyratory crushing is a type of cone crushing, and some say that the hydraulic gyratory crushing The machine is actually a coarse crushing single cylinder hydraulic cone crusher. Looking at the essence through the phenomenon, the two are indeed similar in many ways, and it is no wonder that the cycle break is attributed to the cone break.
