Diagram of banana sieve parts

Banana sieve is a type of vibrating screen specially used for sieving rubber powder and coal, which has the advantage of high output.

The banana vibrating screen has a slope at the feeding end, which starts at 34°, and then descends at a number of angles to the discharge end, which is about 10°. The screen surface adopts the form of broken lines with different inclination angles, and the thickness of the material layer is unchanged from the feeding end to the discharging end. The ratio of material volume to flow rate on the screen surface of each section is stable, the material layer is high, showing a uniform state, and the screening efficiency is significantly improved, which is 1-2 times higher than the processing capacity of the vibrating screen of the same area. When the content of the material whose particle size accounts for less than 1/2 of the graded particle size is large, the banana vibrating screen has high screening efficiency.

Advantages of Banana Sieve

1. The banana screen adopts different vibration parameters, the number of segments and the inclination angle of the screen surface according to the characteristics of different materials. The inclination angle of the screen surface is relatively gentle, and the number of segments of the screen surface is 4 to 7 broken, which can ensure the best screening process effect. . At the same time, the gentle excessive inclination angle and the large number of segments are beneficial to improve the life of the screen surface.
2. The material flow rate of the banana screen is fast, the material layer is thin, and the processing capacity is large, which can basically solve the problem of wet pulverized coal sticking to the screen surface and blocking holes. It is weakly used for dry coal screening, and the classification offline can reach 6MM.
3. The lower beam supporting the screen surface adopts a special I-shaped beam, and the key parts are connected by torsion shear type high-strength bolts, which are reliable in connection and convenient in maintenance. The connection between the beam and the screen surface system is a high-strength bolt connection, which avoids the problem of local stress concentration and low beam life caused by welding. At the same time, users can easily maintain the screen surface.
4. The banana screen with equal thickness screen has a feeding box with sufficient strength, rigidity and length to prevent the impact of large pieces of material or the improper design of the feeding chute causing large pieces of material to fall directly into the screen surface, resulting in premature damage to the screen surface.
5. LDHB’s equal-thickness screen adopts modular component design, with a high degree of generalization, which is convenient for users to install and maintain; the screen surface can be mesh or plate screen surface, or stainless steel or polyurethane screen surface according to different user needs.
6. The lower part of the screen body adopts steel coil spring for shock absorption, which minimizes the load of the screening machine on the foundation.
