A horizontal screen is a non-conventional design that has unique properties that differentiate it from other types of conventional screen. Its most obvious advantage is its working angle. While conventional screens work at an angle of between 15° and 30°, horizontal screens work in parallel to the ground, or at a slight incline of between 0 ...

Fusion Screens are a revolutionary screen developed from a new technology that "fuses" the screen mesh to the tension ring. Fusion Screens have been designed to eliminate the ...
Vibrations given keep the solid particles moving. Proper selected frequency and amplitude keep the capacity constant. In the case of a vibrating screen, the material to be separated is fed to the top screen and simultaneously the screens are vibrated either electrically or mechanically at a frequency of 1000 to 3500 per minute.
Modify the Screen Deck: Depending on the design, altering the angle or tension of the screen deck can influence the amplitude. Increased screen tension can result in higher amplitude. Increase Power Input: If the vibrating screen is powered by a motor, increasing the motor power (within the design limits) can result in greater amplitude.
