examples
The utility model provides a six quick-witted self-synchronizing drive vibration ball-milling device, this vibration ball-milling device is including the vibration organism 5 that can hold six machines, and vibration organism 5 links to each other with base 6 through the spring all around, and base 6 is fixed subaerial to support the weight of whole equipment. 3 new masses are arranged in the vibrating body 5, and the phase difference of the 3 new masses is 120 degrees, so that the vibration force generated by the vibration exciter 3 to the vibrating body 5 is mutually offset, the severe vibration of the vibrating body 5 is greatly reduced, the environment around the equipment is protected, and the service life of the equipment is prolonged. Each new mass comprises a ball mill and an outer mass 2 connected with the outer periphery of the ball mill through springs, the ball mill is composed of an inner mass 1 as a grinding cylinder and side lugs arranged at the opposite positions of the outer wall of the inner mass 1, and a vibration exciter 3 for generating exciting force is arranged in each side lug.
The spring can provide the elastic force and vibration isolation required by the whole ball milling device;
the grinding barrel is a workplace for grinding materials, a plurality of steel balls with different diameters are arranged in the grinding barrel, and the diameters of the steel balls are determined according to the requirement of the fineness degree of grinding the materials.
When the vibration ball mill is in operation, the vibration exciter 3 generates an exciting force, each inner mass 1 starts to vibrate, and the outer mass 1 connected with the inner mass 1 also vibrates due to the action of the elastic force. When the six exciters 3 are all 0 ° out of phase with each other, the vibrating body 5 can be brought into resonance, thereby generating a large amplitude. The vibrating body 5 has 3 outer bodies 2 and 3 inner bodies 1, and the vibrating body 5 has 3 new bodies. When the phase difference of the 3 new masses is 120 degrees, the vibration force generated by the vibration exciter 3 to the vibration body 5 is mutually counteracted, so that the violent vibration of the vibration body 5 is greatly reduced, the environment around the equipment is protected, and the service life of the equipment is prolonged.
The device adopts six vibration exciters for self-synchronous driving, and sets the working point of the system in the sub-resonance region of the natural frequency of the main vibration system, which is called six-machine synchronous resonance operation. When the whole device works at sub-resonance, because the materials processed by the grinder are sealed in the space of the inner working body, namely the inner body 1, when the whole device works at steady state, the dynamic load of the external load of the device can be considered to be nearly constant, and therefore, the amplitude of the main working body is basically constant. The different kinematic parameters (amplitude, frequency, trajectory, etc.) of the device are selected according to the different characteristics of the material to be ground, and these kinematic parameters are selected according to the characteristics of the specific material to be ground, which can be determined according to the actual working requirements. The rotating speed of the vibration exciter 3 can be controlled by the optimal working point of the device through the frequency converter, so that the working point of the system is set in the optimal working area, and when the rotating speed of the vibration exciter 3 is adjusted, not only the working frequency of the device changes, but also the amplitude changes. Therefore, the grinding accuracy is not controlled solely by the amplitude, but is matched by an optimized combination of kinematic parameters. This region belongs to the near resonance region of the device, also called resonance region.
