A dual-machine self-synchronously driven balanced vibrating crusher

Abstract

The invention belongs to the field of self-synchronous vibration machinery and provides a dual-machine self-synchronous drive balanced vibration crusher, which includes two sets of vibrators, two sets of main vibration springs, two supports, two jaw plates, and two sets of reducers. Vibration spring and vibration isolation body; driven by the self-synchronization principle of the two machines, when the material is broken, the two exciters are driven by the AC motor to drive the eccentric rotor to perform reverse high-speed rotation to generate the exciting force, thereby driving the movable jaw to achieve reverse rotation. The relative motion of the phase realizes that the forces of the two movable jaws in the horizontal direction cancel each other out, achieves a self-balancing state, and ensures that the load transmitted in the horizontal direction is minimized, while achieving the crushing of the material between the two movable jaws. . This invention combines the sub-resonance principle and the self-synchronization principle of dual exciters, and uses the vibration crushing method to achieve very high crushing strength of the crusher, enhance the stability of the system, and achieve energy saving of the crusher. This crusher can achieve a relatively large crushing ratio and can crush super-hard materials.

Description

technical field [0001] The invention belongs to the field of self-synchronous vibrating machinery, and relates to a dual-machine self-synchronously driven balanced vibrating crusher. Background technique [0002] A crusher is a device that crushes mined natural stone according to specific requirements. In 1858, American engineer E.W.Blake invented and manufactured the first jaw crusher; the traditional jaw crusher is widely used in various fields of industry because of its advantages of convenient operation, simple structure, easy maintenance, reliable operation and low price. There are a wide range of applications. The vibrating crusher uses the principle of vibration to generate the exciting torque through the vibrating motor, so that the stones vibrate according to a certain rule, and the materials are crushed through mutual collision and friction. Since the appearance of the first crusher, the production efficiency of the factory has been improved to a certain extent. ...

AI Technical Summary

Problems solved by technology

[0004] At present, the currently used crushers still have the following disadvantages: the crushing chamber has only one movable jaw body, which is driven by a motor to work in one direction, and its vertical stroke is relatively large. Suffering local grinding and peeling, thus giving a reaction force to the jaw plate and making the jaw plate easier to wear. At the same time, most crushers use high-power motors as power sources, and the energy consumption accounts for about 50% of the power consumption of the whole plant in the concentrator. Its working process has low crushing rate, high energy consumption and poor stability, which does not meet the national requirements for energy saving, emission reduction and environmental protection

In addition, it is necessary to lay out lines before use, the installation process is complicated, and there are strict conditions for the qualifications of installers and operators
