Banana screen is a new type of screening equipment . The screen has large processing capacity and can be used for wet and dry screening to replace conventional inclined screens or horizontal screens. So far, two types of banana screens with single-layer and double-layer screens have been developed, and have been popularized in beneficiation and coal preparation plants. Compared with the conventional screening machine, the main advantage of the banana screen is that when the same area of the screen surface is used, the processing capacity of the material can be greatly improved. The screen has been widely used in mineral processing and coal preparation plants that require increased screening capacity but cannot use large-volume screening machines due to plant space constraints. The working principle of the banana screen is similar to that of the single-layer thin sieve in some respects. The inlet end is an inclined surface, and the rear part is composed of several different inclined s
