Why is the stainless steel screen often blocked

In the process of using stainless steel screen plug hole, damage how to do? Reasons, treatment and screen device screen blocking hole common reasons screen blocking hole, mainly have the following 5 kinds: contains a large number of critical material particles close to the separation point. That is, the size of the broken stone particle size with the mesh size critical mesh, stone in the screening process, this kind of particles stuck in the mesh can not sieve smoothly formed plug hole, called the critical plug hole.

There are more materials in the shape of multiple contact points on the sieve hole, and more materials in the shape of flake particles. Due to the reason of crushing or stone itself, the stone guess flake material is more, and the flake material in screening itself can not be screened smoothly, at the same time, the flake material is woven into a network, which prevents the screening of other materials to form a blocking hole. The wire diameter of the sieve mesh is too thick, the mesh aperture is too small and so on.

The screening material is high in water and contains mud and sand and other viscous substances. Due to guess mud, stone or stone washing, fine stone due to the intervention of water, stone each bond is formed on one hand, on the other hand, clay bonded on the screen and make the material difficult to sieve, formation plugging hole, in addition to 4, 1, 2 kinds of the existence of the inevitable, the third and fifth kind is the existence of more or less. And the fixed mesh mesh can not effectively overcome the critical material particles of the screen hole blocking, and then the formation of vibrating screen screening power is not high. The general fixed mesh screen oscillating screen power, even if the increase in amplitude can not effectively deal with the occurrence of hole blocking, and increase the amplitude may affect the service life of the screen machine.
