How to solve the phenomenon of “jumping” in slurry filtration?

When the slurry is filtered, the phenomenon of “slurrying” often occurs. It is the liquid material that cannot be sieved normally. How to solve this problem? Dahan manufacturers share the following methods for each reason. The serous shaker customers with similar problems can solve the problem by self-solving. Here's a detailed introduction:

Solutions:

1. The number of mesh screens selected is unreasonable

Since the slurry usually has a certain viscosity and the weight of the material is heavy, the slurry vibrating screen needs to have sufficient exciting force to ensure the working efficiency and the screening effect of the slurry vibrating screen, and if the selected mesh is too fine. If the sieving speed is too slow, the slurry will accumulate on the screen surface instantaneously. At this time, just contact the vibrating screen manufacturer to replace the screen.

2. Screen surface diameter is too large

In the production process, the larger the model of the slurry shaker, the better, but the need to choose according to the actual production needs. If the diameter of the sieve surface of the equipment is too large, the slurry material will enter the slurry vibrating screen and the slurry jumping problem will occur. This is because different sizes of equipment need to be matched with the vibration motor of the corresponding power to drive, and the output of the slurry material is generally not too large, so once the equipment size is used too much, it will cause the phenomenon of jumping.

3. There is a problem with the steering of the motor.

Check and correct the correct steering of the slurry shaker vibration motor. First remove the shroud of the vibration motor, check whether the eccentric block rotation of the two motors rotates to the outside; secondly, if the steering is wrong, please replace any two phase lines in the incoming power of the electric control box.

The wrong way one (two motors rotate inward), although it can also discharge slag outwards, but the speed is slow; the wrong way two (two motors rotate in the same direction), the vibration force is very small, basically no slag discharge and no material is processed.

4. The grid structure used does not conform to the production of slurry materials.

The screening equipment for slurry materials is mostly a circular vibrating screen. The grid structure used in this type of equipment can be divided into an old loose grid, a mother grid, and an adhesive grid. For example, when the grid structure is used in the production process of the slurry, the phenomenon of skipping occurs when the old pine or sub-mesh structure is used. This is because the grid structure of the old pine type and the mother-mother network is striking the slurry material because the striking force of the cleaning device is large, so the slurry material will jump into the slurry after the slurry material enters the screen surface.

5. The slurry vibrating screen is too strong

Excessive excitation force will also cause the slurry vibrating screen to jump. The vibration force of the vibrating motor is too strong. When the slurry enters the screen surface, the excitation force is too large, and the material jumps. The amount of exciting force can be adjusted by adjusting the unbalanced weight at the upper and lower ends of the motor. Some customers can increase the screening output of the slurry, and during the process of use, the excitation force of the motor will be adjusted to cause the excitation force to be too large and the slurry to jump.

The connection range of motors of different powers has a certain range. If it is too large, it will not only affect the production but also affect the service life of the slurry shaker.

The above is an introduction to the problem of “slurrying” in the filtration process of the slurry material, hope to help you.
