[0032] See also Figure 1 , Figure 2 , Figure 3 as well as Figure 4The working principle of cone crusher is to use the pressure and inertia force inside the conical crushing chamber to crush the material into smaller particles. When the material enters the crushing chamber, due to the design of the conical structure, the material will be compressed and gradually crushed under the rotation of the crushing head. Finally, the material is discharged from the outlet of the crusher with the required particle size.

[0033] When a conventional crushing head is used, the distance between the crushing head and the grinding inner cavity 19 can be adjusted by the eccentric sleeve 110. However, the adjustment distance is generally controlled by the eccentric sleeve 110, which is difficult to meet the needs of some higher requirements for crushing processing. Based on this, the present application provides a self-rotating ore collision crusher, including a crusher body 1 for crushing ore and a grinding cavity 2 arranged inside the crusher body 1;

[0034] The crusher body 1 includes a housing 15, a feed port 11 is arranged at the top of the housing 15, a gear ring 17 is arranged above the housing 15 near the top, a transmission gear 12 is arranged outside the gear ring 17, and the bottom of the transmission gear 12 drives the transmission gear 12 to drive the gear ring 17 to rotate through a driving motor 13;

[0035] An inner cavity 19 is provided on the inner side of the outer shell 15, an eccentric sleeve 110 is provided in the middle of the inner cavity 19, and a crushing assembly is provided, and a grinding cavity 2 is provided on the outer side of the crushing assembly, and a certain distance is maintained between the grinding cavity 2 and the grinding assembly.

[0036] The combination of the gear ring 17 and the transmission gear 12 realizes the rotation of the housing. When in use, the crushing assembly is used, and when rotating, the housing and the crushing assembly can rotate in the same direction, achieving a staggered effect and improving the grinding efficiency.

[0037] The eccentric sleeve 110 can adjust the rotation trajectory of the crushing assembly, so that the crusher can adapt to different types of ores and work requirements, and the operation is more flexible and convenient.

A discharge area 18 is provided at the bottom of the outer shell corresponding to the bottom of the grinding chamber 2 for guiding the discharge of the ground material. The bottom of the outer shell 15 is adapted to the eccentric sleeve 110.

[0042] A transmission rod 111 is provided on one side of the housing 15 , a transmission wheel 16 is installed at one end of the transmission rod 111 , and the other end is adapted to the grinding assembly through a bevel gear, so as to drive the grinding assembly to rotate around the eccentric sleeve 110 .

[0043] The bottom of the housing is provided with a bottom plate 14, and the top is adapted to the drive motor 13. This design ensures a stable connection between the housing and the drive system, so that the entire device can remain stable during operation.

The discharge area 18 designed in this way can effectively discharge the crushed material, thereby improving the operating efficiency and continuous operation capacity of the equipment.

[0044] The bottom of the housing is adapted to the eccentric sleeve 110, which ensures that the eccentric sleeve 110 is firmly fixed inside the device. The stability of the eccentric sleeve 110 is crucial for adjusting the motion trajectory of the crushing assembly, which ensures that the device can operate stably under different working conditions and improves the safety of the device.

[0045] The design of the transmission rod 111 enables the grinding assembly to move along with the rotation of the housing, thereby achieving grinding of the ore. This design can effectively utilize the power of the rotation of the housing, making the movement of the grinding assembly more stable and controllable.

[0046] Through the stable bottom structure and precise transmission system, this crusher can realize efficient crushing and grinding process, improving the operating efficiency and stability of the equipment.

[0047] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 The grinding chamber 2 includes a second shell 24, a cavity 21 is arranged on the inner side of the shell, a convex ring 22 is arranged on the top of the cavity 21, a positioning member 23 is arranged on the outer side of the convex ring 22, and the positioning member 23 is adapted to the inner cavity 19 of the first shell 15.

In addition, positioning members 23 are provided on the outside of the convex ring 22. These positioning members 23 are adapted to the inner cavity 19 of the shell 15, ensuring the stable connection between the shell 2 24 and the shell 15.

[0050] The inner side of the cavity 21 is provided with a plurality of inlay areas 27, which are used to install the grinding assembly. The design of the inlay area 27 allows the grinding assembly to be fixed in a suitable position and ensures its stability and accuracy during the grinding process. By arranging the connecting shaft 26 in the inlay area 27, the extrusion plate 25 can be installed at the corresponding position of the grinding assembly. The function of the extrusion plate 25 is to apply a moderate extrusion force to the ore during the grinding process, thereby accelerating the grinding process. In addition, the outer side of the extrusion plate 25 is set to be rough, which can increase the friction with the ore and improve the grinding efficiency.

[0052] A slide groove is provided on one side of the extrusion plate 25, and a telescopic member 28 is provided inside the slide groove. The telescopic member 28 drives the extrusion bar to rotate along the connecting shaft 26 to adjust the distance between the extrusion plate 25 and the grinding assembly.

[0053] The extrusion plate 25 cooperates with the grinding assembly to apply appropriate pressure and force on the grinding material through rotation, thereby promoting more effective crushing and grinding. A chute is provided on one side of the extrusion plate 25, which allows the extrusion plate 25 to be adjusted during the grinding process to adapt to the ore properties and grinding requirements under different conditions.

[0054] The function of the telescopic member 28 is to drive the extrusion plate 25 to rotate along the connecting shaft 26, so as to adjust the distance between the extrusion plate 25 and the grinding assembly. This design allows the operator to adjust the position of the extrusion plate 25 in real time according to the characteristics of the grinding material and the required grinding effect, so as to maximize the grinding efficiency and grinding quality. The telescopic member 28 is generally a hydraulic rod; the adjustment mechanism of the extrusion plate 25 realizes the fine control of the gap during the grinding process. By adjusting the distance between the extrusion plate 25 and the grinding assembly, the pressure and friction of the grinding material can be changed, thereby affecting the grinding effect, which can meet the characteristics and grinding requirements of different grinding materials, so that the crusher can more flexibly adapt to grinding tasks under various working conditions.
