it carries out crushing work to move the jaw with traditional one and move the jaw crushing chamber into two, adopts two to move the mode that the jaw worked simultaneously, and the effective broken stroke increase of material has increased the number of times that the material receives the impact in broken chamber, and the vertical stroke is little, has reduced wearing and tearing, and the breaker work has improved entire system's energy-conservation nature in the sub-resonance state.
The double-motor self-synchronizing principle is adopted for driving, the alternating current motor drives the eccentric rotor, the two vibration exciters rotate reversely at high speed to generate exciting force, and the phase difference between the exciting force and the exciting force is stabilized at 0, so that the two movable jaws are driven to realize opposite-phase relative motion, each movable jaw has the same speed in the same direction, the materials are bitten into the movable jaws, and the materials between the two movable jaws are crushed. The double-motor self-synchronizing principle is utilized for driving, so that the mechanical structure is more compact, the installation position is more convenient, and the stability of the system is stronger.
The mode of vibration crushing is adopted, the relative displacement of the two movable jaws in the vertical direction is zero, the relative displacement in the horizontal direction is multiplied, the larger crushing ratio can be achieved, and the superhard material (such as chromium alloy ore) can be crushed.
The two movable jaws move in opposite phases, so that the forces of the two movable jaws in the horizontal direction are mutually offset, a self-balancing state is realized, and the load transmitted in the horizontal direction is ensured to be minimum.
