In the process of grinding the material, the movable cone device 40 and the fixed cone device 50 jointly squeeze the material, and the grinding ball 100 rolls along with the movable cone device 40 to be in full contact with the material, so that enough squeezing force can be generated to grind the material. In the rotary cone agitator ball mill, referring to fig. 1, the movable cone device 40 may have an annular structure, and the movable cone device 40 may rotate around the fixed cone device 50, that is, the movable cone device 40 is outside the fixed cone device 50. Alternatively, in other embodiments, the fixed cone device 50 may have an annular structure, and the movable cone device 40 may be capable of rotating around the axis of the fixed cone device 50 in the fixed cone device 50, that is, the fixed cone device 50 is outside the movable cone device 40.
In the above embodiment, the grinding ball 100 is placed in the cavity formed between the movable cone device 40 and the fixed cone device 50, the movable cone device 40 drives the grinding ball to roll, and the grinding ball, the movable cone device 40 and the fixed cone device 50 work together to mix and grind materials together, so that the process can be simplified and the efficiency can be improved when coarse particle materials are processed, so that a better grinding effect can be obtained, and a product with fine particle size can be directly obtained. In addition, the slewing bearing 30 is a large-sized bearing capable of bearing comprehensive load, and can bear large axial and radial loads and overturning moment at the same time, the movable cone device 40 is rotatably mounted on the machine body 10 through the slewing bearing 30, and the driving device 20 can drive the movable cone device 40 to rotate around the fixed cone device 50 through the slewing bearing 30, so that stability of the movable cone device 40 in the rotating process can be improved. The slewing bearing 30 has good bearing capacity, so that the slewing bearing can adapt to the crushing processing of large-particle materials, and the slewing bearing 30 is not easy to wear and has long service life. Through the cooperation of slewing bearing 30 and grinding ball 100, can make the material obtain abundant grinding, increase the effective operating length of spiral cone stirring ball mill to can reduce the maintenance number of times, and then can promote spiral cone stirring ball mill's work efficiency and grinding effect by a wide margin.
In the preferred embodiment, the plurality of grinding balls 100 have different diameters, but each grinding ball 100 has a diameter larger than the minimum clearance between the movable cone device 40 and the fixed cone device 50 to prevent the grinding balls 100 from falling down between the movable cone device 40 and the fixed cone device 50. And, the hardness and strength of the grinding ball 100 are greater than those of the material, respectively, to prevent the grinding ball 100 from being broken during the grinding process of the material. In order to increase the rolling frequency and the moving range of the grinding ball 100 between the movable cone device 40 and the fixed cone device 50, a plurality of stirring paddles 43 for stirring the materials and pushing the grinding ball 100 may be provided on the movable cone device 40, so that the effect and efficiency of grinding the materials can be further improved. The stirring paddles 43 are distributed on the inner wall of the annular movable cone device 40, and the length of each stirring paddle 43 is matched with the size of the gap between the movable cone device 40 and the fixed cone device 50 at different heights. Wherein in all embodiments the grinding balls 100 remain in the cavity at all times and do not fall out.
In addition, as shown in fig. 1, in the preferred embodiment, the fixed cone device 50 may be disposed on the machine body 10 through the buffer device 70, and the buffer device 70 may be capable of absorbing impact force generated during the crushing process of the material, and if the crushing process encounters too hard material or sundries, unexpected damage may be avoided through the buffer device 70 when no overload protection measures or protection is unreliable. The movable cone device 40 and the fixed cone device 50 can be matched with each other to crush, meanwhile, the fixed cone device 50 can be prevented from being damaged due to impact force, and forced shutdown maintenance caused by damage of the fixed cone device 50 or huge damage of a plurality of important parts of the machine body is avoided, so that the service life of the fixed cone device 50 can be greatly prolonged, and further the production time can be saved and the production efficiency can be improved.
In the above embodiment, the damping device 70 may have various forms as long as it can damp the vibration of the cone fixing device 50 during operation. In a preferred embodiment, referring again to fig. 1, the damping device 70 may include a plurality of guide rods 71 spaced around the cone device 50 and elastic members 72 sleeved on the guide rods 71, and the elastic members 72 are precompressed between the cone device 50 and the machine body 10, so as to damp vibrations transmitted from the cone device 50 to the machine body 10. The number of the elastic members 72 may be plural, and the plurality of elastic members 72 may be sleeved on the guide rods 71 in a one-to-one correspondence, so that the plurality of guide rods 71 are uniformly distributed at intervals along the circumferential direction of the fixed cone device 50, and the force applied to the fixed cone device 50 by the movable cone device 40 can be uniformly dispersed, thereby effectively avoiding the fixed cone device 50 from being defective due to the impact force generated during the material crushing.
Further, one end of the guide rod 71 is mounted on the cone fixing device 50 and the other end is mounted on the machine body 10, and the guide rod 71 can slide with respect to the cone fixing device 50 and/or the machine body 10. For example, one end of the guide rod 71 is fixedly mounted on the cone fixing device 50, and the other end of the guide rod 71 is movably mounted on the machine body 10; alternatively, one end of the guide rod 71 is mounted on the fixed cone device 50 and is capable of sliding on the fixed cone device 50, and the other end of the guide rod 71 is fixed to the machine body 10. One end of the guide rod 71 is mounted (may be fixedly mounted or slidably mounted) on the fixed cone device 50, and the other end of the guide rod 71 is movably mounted on the machine body 10 and can slide along the extending direction of the guide rod 71 on the machine body 10, that is, the fixed cone device 50 can slide along the axial direction of the guide rod 71 relative to the machine body 10 within a certain range. When the elastic member 72 is provided between the machine body 10 and the cone fixing device 50, the vibration damping effect can be achieved. Specifically, the cone fixing device 50 is deflected downward by a certain distance due to vibration during operation, and the deflected vibration is absorbed by the elastic member 72, so that the vibration transmitted to the machine body 10 can be reduced, thereby achieving the purpose of buffering and vibration reduction.
As shown in fig. 1, the guide rod 71 may be a mounting bolt or a mounting stud, and the fixing cone device 50 and the machine body 10 are provided with mounting holes, the mounting bolt is mounted in the mounting holes, the mounting bolt is provided with a mounting nut, and the machine body 10 and the fixing cone device 50 are located between the mounting nut and the bolt head of the mounting bolt. The elastic member 72 may be a spring or a rubber sleeve, etc., and the elastic member 72 is sleeved on the guide rod 71, so that vibration transmitted from the fixed cone device 50 to the machine body 10 during the operation of the rotary cone stirring ball mill can be reduced, and the vibration is prevented from affecting the service life of each bolt or screw, so as to ensure the connection stability between each component on the machine body 10. More importantly, due to the existence of the elastic piece 72, the acting force between the fixed cone device 50 and the material and the movable cone device 40 is dispersed, so that the abrasion of the fixed cone device 50 and the movable cone device 40 can be reduced, and the service life of the rotary cone stirring ball mill is prolonged.
In addition, in a more preferred embodiment, the mounting bolt may be further sleeved with a limit nut, and the elastic member 72 is located between the limit nut and the fixed cone device 50, so as to adjust the compression pre-tightening force of the elastic member 72 according to working conditions, so that the offset range of the fixed cone device 50 in the working process can be adjusted, and the application range of the rotary cone agitator ball mill is improved. For example, when crushing large particulate material, the stop nut may be moved away from the side of the cone device 50 to increase the range of deflection of the cone device 50.
In further embodiments, the damping device 70 may also include a plurality of damping cylinders spaced around the fixed cone device 50, one end of the damping cylinder being connected to the fixed cone device 50 and the other end being connected to the machine body 10. The hydraulic oil in the buffer hydraulic cylinder can absorb the vibration transmitted to the fixed cone device 50 when the materials are crushed, and the position deviation of the fixed cone device 50 can be converted into the telescopic movement of the buffer hydraulic cylinder, so that the purpose of buffering and vibration reduction is achieved.
Further, in a more preferred embodiment, as shown in FIG. 2, the cone agitator ball mill further includes a dust guard assembly 90 disposed between the slewing bearing 30 and the fixed cone device 50 and surrounding the fixed cone device 50 for preventing material spillage. Wherein, through the cooperation of slewing bearing 30, grinding ball 100 and buffer 70, can increase the effective operating length of spiral cone agitator ball mill to can reduce the maintenance number of times, and then can promote the work efficiency of spiral cone agitator ball mill by a wide margin. Just because the buffer device 70 can greatly affect the working efficiency of the whole machine and the service life of important components, the buffer device 70 needs to be particularly protected to improve the reliability of the buffer device 70. The dust blocking assembly 90 is arranged between the slewing bearing 30 and the fixed cone device 50, the sealing is reliable, and the material can be prevented from overflowing from the middle of the machine body 10, so that dust generated by crushing the material is prevented from affecting the performance of the buffer device 70, the cleaning of moving parts (the buffer device 70, the fixed cone device 50 and the like) is ensured, the normal operation of key working parts such as the slewing bearing 30 is protected, the lubrication is smooth, and the environment is also prevented from being polluted by dust. Wherein during operation the cone device 50 will follow the buffer device 70 for a small range of polarization.
The fixed cone device 50 comprises a mounting frame 51 and a fixed cone cylinder 52 arranged on the mounting frame 51, a lining plate 53 is arranged on the outer peripheral surface of the fixed cone cylinder 52, the surface of the lining plate 53 is a smooth surface, and the lining plate 53 is made of wear-resistant materials, so that the service life of the fixed cone device 50 is prolonged, the maintenance time is shortened, and the production efficiency is improved. Wherein, the fixed cone cylinder 52 can be provided with a lining plate 53 by a fastener (such as a screw, etc.), so as to facilitate the installation and the disassembly. Wherein the buffer device 70 is located between the mounting frame 51 and the body 10. After the materials are ground between the movable cone device 40 and the fixed cone device 50, the materials directly overflow from a discharge gap at the lower part of a grinding cavity formed by the lining plate 53 on the fixed cone cylinder 52 and the lining plate on the movable cone device 40, and pass through the inverted cone cylinder 60 until reaching a discharge hole 62. Referring to fig. 2, the dust blocking assembly 90 includes a dust blocking ring 91 fixedly mounted on the mounting frame 51, and a seal felt 92 disposed between the dust blocking ring 91 and the slewing bearing 30 (specifically, a bearing ring under the fixing ring 31). During the operation of the rotary cone agitator ball mill, the mounting frame 51 will follow the buffer device 70 to deflect up and down, so the dust blocking ring 91 will deflect up and down, and the gap during the deflection of the dust blocking ring 91 is sealed by the sealing felt 92, so as to prevent the crushed material between the fixed cone device 50 and the movable cone device 40 from overflowing from between the machine body 10 and the buffer device 70, so as to improve the dust blocking effect.

Wherein, the mounting ring 913 is fixedly installed on the mounting frame 51 through a plurality of bolts located at the outer side of the connection ring 912, so as not to be polluted by dust, thereby securing the fastening effect. The connecting ring 912 is in a shape with a big top and a small bottom, and the lower end forms a necking, so that the material or dust entering the connecting ring 912 can fall down along the inclined inner wall and then pass through the mesh of the mounting frame 51.
