Structure of the Composite Sync Vibrating Jaw Crusher
Posted Oct 12 2012 2:49am
The structure of the composite sync vibrating jaw crusher is a new program, which has completely got rid of the traditional frame mode of the jaw crusher. The two exciters with the same structures are installed on both sides of the cone, which can easily adjust the crushing force by adjusting the eccentric block of the exciter. The dip angle of the cone surface of inner cone is relatively large, which can improve the production capacity. The inner crushing cone includes the conical surface and the cylindrical surface which can avoid the overcrushing caused by the too large crushing force. The whole machine is located on the vibrating isolation spring which does not require a large and sturdy foundation. Compared with the KH / I inertia jaw crusher, the composite synchronous vibrating jaw crusher has larger crushing ratio, which can be used to process the materials with any strength. The composite synchronous vibration jaw crusher can be started and stopped with load. There will be no overload when the foreign bodies fall into the crushing cavity. In addition, there is no need to configure the supporting equipment and it has simplified the crushing technical process. It also has the advantages of low height of the entire machine, simple structure, easy manufacture and installation, easy maintenance, low power consumption, good characteristics of the product size and low investment without complex spherical plain bearings. The composite synchronous vibration jaw crusher uses the combination of the vibration synchronization and control synchronization, which belongs to the all-digital control system. The two AC induction motors to drive the two eccentric rotors are respectively defined as the main motor and servo motor. Controlling the servo motor to track the main motor can achieve the tracking control. The startup and shutdown of the main motor is controlled by the magnetic drive. The AC control back routing the magnetic drive is controlled by the solid state relays. For the DC control end connection of the solid state relay, when DC is high, the drive is turned on and the motor starts. Therefore, you can control the start and stop of the main motor by the software control. A high-performance frequency converter supplies power for the servo motor. The output and control of the frequency converter is the modulation which uses the V / f as the definite value of the sinusoidal pulse width. The low-frequency voltage is used as the compensation. The output frequency of the converter is determined by the DC voltage of the control terminal. We must achieve the tracking control of the servo motor to ensure that the synchronized operation of the entire mechanical with the same direction to improve the mechanical properties of the new vibrating jaw crusher.
