Banana Screen

The banana screen uses the latest technology of multi-angle machines, which can achieve special throughput in a relatively small screening area. The screen includes many different screen angles, a variety of deck types and apertures to meet specific process requirements. Banana screen is sometimes called multi-angle screen or multi-slope screen. will accept most types of deck systems, including polyurethane, perforated steel plate and wedge wire. Banana screen achieves good separation accuracy under extremely high feeding speed and material that is difficult to screen. Its operational characteristics make it a high-speed screen.

Banana screen is made up of motor and vibrator as vibration source, the vibrator is mainly by the eccentric shaft, pulley, bearing and bearing seat, the vibrator is installed on the screen box side plate, and by the motor through v-belt or soft connection and is linked together, the motor drives the eccentric shaft rotation, generate centrifugal force, forced vibration sieve box.


1. The banana screen adopt multi-section screen deck, which is conducive to material ejection, reduces the blocking hole rate and greatly improves the screening efficiency.

2. The side plate is made of high strength structural steel with high precision CNC cutting to ensure the overall machining accuracy.

3. The screen box frame is connected by high strength rivets and all welding parts are treated with stress elimination to ensure the reliability of banana screen operation.

4. The beam is a rectangular seamless tube structure, with higher cross section strength, and the beam surface is sprayed with polyurea to ensure the wear resistance, corrosion resistance and impact resistance of the beam surface.

5. The spring of the banana screen is made of metal spiral steel spring with rubber composite spring, which has the characteristics of small amplitude, low noise and long life in the over-resonance area.

6. The banana screen use of modular design of parts, to facilitate timely and rapid replacement of parts, reduce downtime and maintenance costs.

vibration exciter & screen plate
The vibration exciter of the banana screen adopts high precision carburizing and quenching helical gear transmission to ensure the bearing capacity and working stability and reliability. Vibration exciter box is completed at one time by CNC machining center and tested by three-coordinate detector.
Sealing using international famous brand oil seal to ensure that the lubricating oil is not leaked during work. At the same time, magnetic oil plug absorbs fine metal shavings inside the to vibration exciter purify lubricating oil.
The vibration exciter uses SKF or FAG special bearings of vibration equipment, which can ensure reliability under vibration load.

banana screen vibration exciter
1. Using thin oil lubrication, bearing lubrication is more full, bearing bearing capacity is larger, longer life
2. Vibrator temperature rise is small, heat dissipation is fast, the whole system does not leak oil, to ensure clean production
3. The overall structure is light, good sealing, durable and reliable, cost-effective, simple and convenient installation and maintenance.

The banana screen adopt HW12 structure self-cleaning polyurethane screen plate, has a good ability to remove the sticky material, can shake off the sticky in the screen plate, sieve hole 
Powder, save manpower, reduce power consumption, provide good production conditions for sintering and blast furnace using professional data simulation analysis, according to user needs to solve the problem of wall hole. Not easy to deformation, fracture, long service life, and at the same time greatly improve production efficiency and output. 

the type of banana screen plate
(Screen plate with different shapes of screen holes)
1. The flexible characteristics of the screen surface are not only conducive to the better conduction of the vibration force of the screen plate, but also the good fastness of the screen plate connection; 
2. The modular design can ensure that under the original production process conditions, to achieve the maximum effective screening area and maximum efficiency and replacement economy: 
3. Soft connection to shaker In addition to abnormal wear factors caused by screen plate damage, longer life, with help to save the production cost of users. 
4. Good moisture resistance, can work under the condition of water as the medium, and in the case of water, oil and other media, polyurethane and material friction coefficient is reduced, more conducive to sieve, improve screening efficiency, and can avoid the adhesion of wet particles, at the same time because of friction coefficient reduction, wear reduction, improve service life. 
5. Due to reasonable screen design, unique screen plate manufacturing process, limit size particles will not block the screen.
