The curved vibrating screen is a linear vibrating screen with a box vibrator and multiple screen surfaces with different inclination angles. Because the shape of the screen box is similar to that of a banana, it is also called a banana screen. It is mainly used for the classification of medium and fine-grained materials with high content of fine particles. It can also be used for dewatering, de-intermediation and desliming operations (fine particle size refers to particles whose particle size is less than half of the mesh size). It can carry out dry and wet classification for small and medium particles of coal, coke, ore, gravel, or other materials. It is a large-scale vibrating screen commonly used in large coal preparation plants, coal washing plants, sintering plants, pelletizing plants, and ore dressing plants.
