For the linear vibrating screen, the problem that the material conveyed by the
linear vibrating screen is not smooth and the material deviates is an "old problem". The main factors are:
Vibration motor tilt angle
The motor tilt angle of the linear vibrating screen is generally fixed, some can be adjusted, and some cannot be adjusted. Such conditions will generally change the direction of the excitation force for adjustment. According to the material condition and handling capacity, the included angle of the eccentric block is generally adjusted for the vibration motor to adjust the magnitude of the excitation force. For linear screen with double eccentric block and shaft, the eccentric mass of eccentric block can be adjusted to increase the excitation force, change the phase angle of double eccentric block and shaft, and change the direction of excitation force.
Strength and damage of damping spring
For linear vibrating screen, the importance of damping spring is no less than the vibration motor mentioned above. It plays an important role in maintaining the stability of the vibrating screen and extending its life.
Center of gravity of linear screen and eccentric block position of vibrating motor
There are almost no such technical problems as the position of the center of gravity of the linear screen itself or the eccentric block of the motor produced by the regular beneficiation equipment manufacturer. After inspection, the technical experts confirmed that the center of gravity of the linear vibrating screen itself was stable and the position of the eccentric block of the motor was balanced.
Screen box deformation
The screen box usually refers to above the vibrating motor and below the feeding opening, which is composed of the screen frame and the fixed screen surface around it. When the linear vibrating screen works, the screen frame needs to bear the gravity of the screened material and the strong excitation force of the vibrating motor at the same time. If the strength is not enough, the screen frame is easily deformed and damaged.
The operation of linear vibrating screen is related to many aspects, including the technical parameters of the equipment itself, whether the operation is standardized and regular maintenance. The vibrating screen technical experts suggest that: first, please purchase equipment from the regular beneficiation equipment manufacturer to ensure the equipment quality; In addition, in the daily production, the operating experts should be familiar with the working principle, performance and common fault phenomenon of the vibrating screen, and do a good job in the daily maintenance to reduce the fault rate and improve the work efficiency.
