Solution to the slow feeding of high-frequency vibrating dewatering screen

Release time:May.11.2024 Views:0

As one of the important equipment in the field of solid-liquid separation,(xingaonai) the high-frequency vibrating dewatering screen may have slow material feeding problem caused by the various factors mentioned above. You can try the following solutions:

1. Check whether the vibration motor is installed correctly. If there is any problem, adjust or repair it in time.

2. By increasing the excitation force of the vibrator, the amplitude and vibration intensity of the screen are increased, thereby promoting the movement and separation of materials.

3. According to the characteristics of the material and the capacity of the dehydration screen, appropriately adjust the feeding speed and amount to ensure uniform and continuous feeding, so that the material is evenly distributed and fully dehydrated on the screen.

4. Check whether the shock-absorbing spring and other parts of the screen body are aged and loose. If there are any problems, they should be tightened or replaced in time. At the same time, attention should be paid to checking whether the components are worn or damaged, whether the fit clearance is appropriate and the performance status. If there are any problems, proceed in time. Adjust or replace.

5. For the problem that the center of gravity of the dehydration screen itself is unstable or the eccentric block of the motor is unbalanced, the motor position can be readjusted or a new motor can be replaced.

6. When purchasing dewatering screens, you should pay attention to choosing products with reliable quality and reasonable prices. For equipment that has been purchased and used, measures such as regular inspection of the materials and stiffness of each component can be taken to ensure that the overall stability of the equipment is good.

7. For large-scale, high-frequency linear dewatering screens, measures such as strengthening the strength of the screen box can be taken to prevent screen box deformation problems. At the same time, the screen box should be kept level to ensure the normal flow of materials on the screen surface.

8. Regularly check whether the screen is blocked. If there is any blockage, clean the debris and blockages on the screen in time to keep the screen smooth and running normally. In addition, manufacturers can customize the appropriate screen structure and materials according to the particle size distribution and fluidity of the material to improve the permeability and dehydration efficiency of the screen.

9. Adjusting the screen tension is the key to increasing the discharge speed. You can open the top support bolt of the dewatering screen, loosen the support rod, adjust the appropriate screen tension, and then lock the support rod.

10. For finer materials containing a large amount of finer grades, an auxiliary screening method can be added. An auxiliary screen with a larger mesh size sieve is used to pre-screen the grade of the product on the sieve.


In short, solving the problem of slow feeding of vibrating dewatering screens requires starting from multiple angles, including materials, screens, vibration and equipment. Only by comprehensively considering and taking corresponding measures can this problem be effectively solved and the production efficiency guaranteed. Goes smoothly.

In addition, it should be noted that different types of high-frequency vibrating dewatering screens may have different material conveying speeds and dehydration effects when processing different materials. Therefore, in actual operations, appropriate adjustments and optimizations need to be made according to specific conditions.

Routine maintenance

1. Before using the high-frequency dewatering vibrating screen every day, check whether the anchor bolts are loose and whether the screen frame collides with the chute.

2. When the equipment is operating, if the screen feed concentration should be controlled at about 40%, it will help to improve the classification efficiency in the future.

3. The exciter must be covered with a rubber plate to prevent slurry and water from entering, causing blockage or short circuit. It is strictly forbidden to spray water on the electromagnetic exciter and control box, which may easily lead to short circuit.

4. After the equipment has been operated for more than 1500 hours, the bearing status should be checked. If it is seriously damaged, it should be replaced immediately.

5. The sieve plate needs to be removed after 1 month of use, and the direction should be changed 180 degrees to enhance the "cutting" effect of the sieve bar and improve the classification efficiency.

6. When the high-frequency dewatering vibrating screen is restarted after it has not been used for a long time, first measure the insulation resistance. The resistance should be measured at 500 volts and gigameter, and should be greater than 0.5 MHz.
