Since the vibrating screen may break, fail to start, or run out of deviation and other large jumps during long-term use, do you know why these situations occur?
1. The vibration force of the vibrating screen is too large
If the power of the vibrating screen does not match the model during operation, it may cause a large displacement or jump in the use time.
2. Improper installation
If the ground is uneven or improperly installed during the installation of the vibrating screen, it will cause excessive vibration, so it is recommended that you pay more attention when installing it.
3. The anchor bolts are loose
Due to the long-term operation of the vibrating screen, the anchor bolts will be loosened under long-term vibration, which will cause the vibrating screen to produce greater vibration. In view of this situation, it is recommended that you regularly check and tighten the anchor bolts.
4. The hardness of the damping spring is too large
The damping spring is a component that connects the base of the screen and the frame of the screen. It has a buffering effect. If it is too hard, the buffering effect may not be achieved, causing the equipment to run off.
5. The rotation of the motor is inconsistent with the power
If the vibrating motor of the vibrating screen is worn or damaged, when the user replaces the motor, the rotation of the motor is inconsistent with the power, which may cause the vibrating screen equipment to vibrate violently.

The main function is twofold:
1. It plays the role of gathering materials, especially in the powder screening process, which can well solve the problems of flying, scattering and other environmental pollution and wasting materials that are prone to powder in the feeding and discharging process;
2. It plays the role of cushioning and shock absorption. The soft connection of the colloidal vibrating screen between the equipment can effectively slow down the wear and noise of the vibrating screen when it comes in contact with other equipment under high-frequency vibration.
Advantages and features:
1, the soft connection can provide a larger axial, angular and lateral displacement in a smaller size range, especially the corrugated soft connection;
2. It can simplify the design, avoid the design and installation of complicated pipelines, and is easy to disassemble, saving a lot of materials and labor;
3. It has obvious noise reduction and shock absorption function, especially the silicone material J has abrasion resistance, which can effectively reduce the noise and vibration generated by the vibrating screen system;
4. It has good high temperature resistance and corrosion resistance, so that it can avoid the flying and scattering of powder materials during the feeding and discharging process, and at the same time, it will not pollute the materials.

1. The influence of support spring on vibrating screening
During screening, if the stiffness of the support spring of the vibrating screen is inconsistent, it will cause an imbalance in the support of the screen. This requires the user to check before starting to ensure that each position is consistent in height before starting the device.
2. Poor rigidity of the screen frame
The screen frame needs to be pressed tightly during installation. The uneven force or poor rigidity of the screen frame during screening will cause the material to deviate. The movement of the screen body is twisting, not translation, and a strong vibrating screen should be used for production during screening.
3. The excitation force on both sides of the screen is uneven, resulting in different amplitudes on both sides
In view of this situation, it is necessary to adjust the eccentric block of the vibration motor in time to make the motor amplitude the same.
4. Uneven feeding at the production site
In the use of the vibrating screen, ensuring uniform feeding can effectively avoid unnecessary failures during the production and use of the vibrating screen.

1. The power model of the vibration motor is too large, the excitation force is too large, and the load exceeds the normal load of the vibrating screen, and the motor base is damaged due to long-term operation.
2. The thickness of the steel plate of the motor base is designed to be too thin, which may cause cracking due to long-term operation.
3. There is a problem with the steel plate material.
4. The welding quality does not meet the qualified requirements.
5. The installation position of the motor does not meet the design requirements of the vibration mechanics specification.

a. Before using the air flow screen for the first time, please read the air flow screen instruction manual carefully, and use the air flow screen equipment in strict accordance with the requirements of the manual;
b. Do a good job of daily maintenance such as cleaning, lubricating, fastening and anti-corrosion of the air flow screen, so that the equipment is kept clean inside and outside, with good performance, and a safe and reliable state;
c. The main engine, motor, and fan of the air flow screen should be checked regularly, lubricating oil should be added regularly, dust in the motor should be removed, and a thorough overhaul should be guaranteed once a year;
d. Airflow screen equipped with a vibration exciter, which must be overhauled 1-2 times a year, add lubricating oil regularly, and check whether the connecting bolts are tight;
e. The screen of the air flow screen should be evenly tensioned when it is replaced. When fixing the steel wire ropes at both ends, the screen should be tightened while adjusting;
f. The electrical control box of the air screen should be kept tidy to prevent dust from falling into the control box, causing electrical components to malfunction or short-circuit;
g. Regularly check whether the grounding wire of the air screen and the cable of the power switch are well connected. If there is any aging phenomenon, it should be replaced in time.
