Anping Tianshan Wire Mesh Co.,Ltd is a wire mesh enterprise,who pecializes n the production and export of wedge wire screen and johnson screen

1. Construction of wedge wire curved screen
    Wedge wire Curved screen is a screen surface for the arc to open away from wet fine screening equipment. According to the different feeding methods are divided into gravity and pressure arc curved sieve screen. Artesian curved screen is a small curvature, low pressure, low-speed feeding curved screen, thanks to a certain height difference of the feed material screening and to the mouth, along the arc tangent in the direction screen surface for gravity feed. Pressure is a sweeping curved screen, high-pressure, high-speed feeding curved screen, which is the use of sand pump nozzle into the raw material to the slurry under the action of the material at high speed along the curved screen surface tangent to the direction of the pressure feedstock.
    The role of China's coal preparation plant are mostly gravity curved screen

    circular surface, by the cross section with a rectangular or slightly trapezoidal section of stainless steel or nylon sieve of sieve composition. Sieve slurry of direction and movement in the sieve by the perpendicular. Slurry tank from the things of the mouth by tangential direction along the curved uniformly in Yu wide screen to enter the slurry along the screen surface during the campaign are divided into sieve products and products under the sieve. Arc Screen feeding pressure head is generally 300 ~ 500mm, height restrictions, such as by the plant, its pressure Ga may also be less than 300mm. Arc screen specifications in order to screen surface curvature radius R, the width B and the screen surface curvature α, ie the R × B × α. Gravity Arc screen surface curvature over 45 °, 60 ° and 90 ° and so on.

2. Wedge wire Curved screen work princinple

    Slurry with a certain speed along the tangential direction to the entry screen surface, due to the role of centrifugal force, so that slurry layer close to screen surface movement. When the slurry layer consists of one screen to another root of the flow of the process of screening, each side edge of the root sieve slurry layers are generated on the cutting effect. Victims have been cut this part of the slurry, under the centrifugal force through sieve slit discharged into the next screen products; not cut the part of victims of slurry across the screen arrhizus product of a sieve. Each of harm to take root sieve sieve downstream beam thickness is about one-fourth of screen width of gap. The products under the largest screen size than the autonomy of the sieve screen under the downstream beam cut twice as thick. Therefore, the classification of curved screen size is about half the width of the sieve.
    As the curved screen of the screen under the product produced by screen edges if the edges of the slurry layer to cut income, therefore, screening the first side of the sharp edges of the screen under the level of volume and size are directly related to classification. With the screen edges edges of the wear and tear, under the production rate and particle size sieve were significantly reduced. Move, in order to sprocket-driven, speed 11r/min ......
