The shape of the sand and gravel, the critical particle size of the mesh, the thickness of the wire mesh, and the shape of the mesh are all factors that may cause the mesh to block.
(1) It contains a large amount of crushed rock whose particle size close to the screen mesh. During the screening process, those crushed materials can not be smoothly screened in the mesh to cause blockage, which is called critical plugging.
(2) Too many flaky shape materials. The flaky shape material cannot be sieved smoothly, and as the flaky shape material piles up, it hinders the screening of other materials, causing plugging.
(3) The sieving material has high moisture content and contains viscous mud.
When the material contains much mud, the fine-grained material and mud is easy to agglomerate due to the intervention of water, and some soil is bonded to the sieve surface, making the material difficult to be sieved, resulting in plugging.
(4) Screen mesh and steel wire diameter
The practice has proved that the same mesh, too thick steel wire will cause a significant increase in the probability of plugging.

Control the shape of the material
In the stone crushing line, the content of the needle-shaped stone should be as low as possible to prevent the screen from being clogged.
Most of the stone plants use two crushing stages. For the primary crushing, the jaw crusher is easy to produce flaky shape rock. The secondary crusher often uses impact crusher. In order to reduce the flaky-shaped rock ratio, the first crushing size should not be too small.
Reasonably adjust the tension of the screen
Reasonable adjustment of the tension of the screen is an effective method to reduce the hole plugging. The reasonable tensioning force causes the screen to produce a slight secondary vibration with the support beam, thus effectively reducing the occurrence of plugging.
