Vibration resistance,large load, High strength Vibrating screens are devices used for sorting and separating various materials according to their particle size, Using vibrations, the material moves across the screen surface, Finer particles fall through the screen, while coarser particles move down the screen and return, for example.to the crushing phase. Vibrating screens are used in various industrial sectors, such as mining construction,and waste recycling.
