Banana Screen

lThe principle is to inject the multi-stage dip angle for screen surface on the basis of the horizontal screen surface of the linear vibrating screen. A larger inclined screen surface is designed at the feeding end of the screen, and then it descends step by step at a certain number of angles until it reaches the discharge outlet, so that the overall screen surface is concave arc shape similar to that of the fruit banana,so that the whole screen surface is concave arc, and its shape is similar to that of fruit bananas.

lThe material moves at different speeds and projectile strengths on each stage screen surface to meet the needs of different particle sizes thorough passing through the screen. The large and small particles on the screen surface are loose and layered obviously. The large materials pass through the steep slope of the feeding screen stage quickly, and the small materials settle rapidly. This early layering makes the fine particles close to the screen surface faster, and can pass through the screen aperture gap relatively unimpeded, and become the undersize material. Therefore, the capacity of the banana screen is 1.2-1.5 times higher than that of the conventional screen.

lThe concave arc multi-stage screen surface , with long effective screen surface and decreasing dip angle of each screen surface in turn. It has the principle of equal thickness screening, large capacity and high screening efficiency. Driven by one set motor, two box-type vibrators are installed on the supporting main beam of the screen frame, the helical gear is forced to drive, the bearing is lubricated by thin oil splashing, the rigidity is high, the projectile angle is stable, the operation is reliable and the failure rate is low. Large capacity per unit area and high screening efficiency. (Width 2.4-4.9m).

lThe company is the earliest manufacturer of banana screen in China. Its banana screen is rated as "special, refined, special and new" product at the provincial level, and also listed as the national key new product; At present, the products have been applied to more than 1000 sets in coal, mining and other industries. At present, the largest production model is ZXT4985.

lThe company divides banana screens into two types: for classification and for dewatering, de-medium and desliming. The number of screen surface stages is 5-7, the classifying angle is 10-35 °, and the classifying speed is 0.45-3m/s; De-medium angle: 5-25°, De-medium speed: 0.35-1.7m/s. The vibration direction angle is 45 °, the vibrating frequency is 900r/min, the amplitude is 10-11mm, and the vibration strength is 4.5-5g.
