What Is The Mechanism And Working TSX Principle Of The Sieve Bends Screen?

The sieve bends screen consists of a group of fixed screen bars arranged on the sieve bends surface. The upper part of the screen surface is a feeder, which is wide at the top and narrow at the bottom. The slurry with a moisture content of about 30% is sent to the screen surface along the tangent direction of the sieve bends surface at a certain speed through the narrow slit discharge port at the lower part of the feeder.

The slurry is subject to gravity, centrifugal force and the resistance of the screen bar to the slurry on the screen surface, making the slurry move closely to the screen surface. The movement speed of the lower layer slurry near the screen bar is low.

In the process of flowing from one screen bar to another, due to the cutting effect of the edge of each screen bar on the material layer, a layer of slurry with a thickness of about 1/4 of the size of the screen hole and the fine particles in it will be cut by the edge and discharged under the screen to become underscreen products, while the slurry and coarse particles not cut by the edge will cross the screen surface and be discharged from the end of the screen surface, Become a product on the sieve.

Because the sieve bends screen relies on the edge cutting of the screen bar to screen materials. Therefore, whether the edges of the screen bar are sharp and the particle size will determine whether the particles are discharged into the product under the screen or the product on the screen. Therefore, whether the edges of the screen bar have been blunted has a great impact on the screening effect of the sieve bends screen.

The relation between the grading particle size of the sieve bends screen and the size of the sieve aperture is roughly that the grading material size is equal to half of the sieve aperture width. However, with the wear of the edges of the screen strip, the grading particle size and the product output under the screen will be significantly reduced.

Since the grading particle size of the curved screen is roughly equal to half of the screen opening width, the particle size of the products discharged into the screen is much smaller than the screen opening width, so the possibility of screen opening blockage is greatly reduced.
