How to solve the problem of clogging of the vibrating feeder

Vibrating feeders are generally made of stainless steel welded mesh screens, but the size of their screen seams can only reach 0.25mm, and the screen surface has a low open rate. Therefore, when dealing with large moisture and sticky materials, the screen plugging phenomenon is likely to occur. Dehydration effect. The newly developed laminated composite screen is composed of stainless steel meshes with different mesh sizes, and the perimeter is made of polyurethane rubber to form the first mesh with the smallest mesh, which is called the main mesh; the second layer The aperture of the screen is larger than the first screen by one hole sequence, which is called a blocking screen.

Vibrating feeders

The strength of the third layer of the screen is as large as possible and the diameter of the steel wire is as small as possible to increase the opening rate of the screen. The porosity of this layer can reach 40%, and the first and second layers of the screen can be supported to keep it large enough. Strength and rigidity, but also to avoid the first and second layer of the screen due to the coarse diameter of the wire to form a collapse, and even affect the screen life, in addition to the unique technology developed into a highly efficient multi-frequency small vibration feeder, mainly Some of them are flake-shaped in the horizontal direction, and the rear part of the sieve plate forms an up-tilt angle with the main plate, which not only makes it difficult for the pulp particles to pass through the sieve holes, but also has high efficiency.
Because the screen diameter of each screen is different, the screen will not be deformed after being forced to stretch. In addition to the composite screen vibrating along with the screen, there is relative movement between each screen, that is, the screen surface. The relative misalignment motion between the upper and lower tapping movements and the transverse direction, which facilitates the passage of fine materials through the screen holes and prevents clogging, has the effect that a single screen does not have, that is, prompts the fine-grained materials to pass through the screen quickly and automatically. Cleaning the sieves has a special significance for slime recovery and grading of fine-grained materials.
