The principle of linear vibrating screen is driven by two horizontal YZU vibration motors. When two vibration motors are synchronously and reversely rotated, the exciting forces generated by the eccentric blocks cancel each other in a direction parallel to the motor axis, perpendicular to the motor. The direction of the axes is a combined force, so the trajectory of the linear vibrating screen is a parabolic advance.

The two motor shafts have an inclination angle with respect to the screen surface. Under the combined force of the excitation force and the material self-gravity, the material is thrown up and jumped forward in a linear motion on the linear vibrating screen surface, thereby achieving the purpose of screening and classifying the materials. Linear vibrating Screen of various dry powder materials with a particle size of 0.074-5 mm, a water content of less than 70%, and no stickiness. The maximum feed size is not more than 10 mm. It can be used in the assembly line to achieve automatic operation, featuring low energy consumption, high efficiency, simple structure, easy maintenance, and no closed dust in the fully enclosed structure. The highest linear vibrating screening number is 325 mesh, and 7 different particle sizes can be screened out.
The cause of the failure of the linear screen:
1. Uneven material feeding causes partial pressure on the linear vibrating screen surface to be too large, and there is no material on the other screen surface.
2. The sieve plate (screen) is not tensioned or damaged, and the linear vibrating screen surface appears to vibrate twice, and the material appears to be stagnant.
3. The damping spring has a broken or inconsistent stiffness.
4. The angle of the eccentric block of the vibration motor is inconsistent or the vibrator is assembled differently. The two vibration motors rotate in the same direction and are not inward or at the same time.
5. The motor power is inconsistent. The operating frequency of the vibrating screen is the same as the fixed frequency of a certain part to generate resonance.
6. The foundation is not on a level surface and the equipment is not fixed.
