Coal Banana Vibrating Screen

Our multi-stage inclined coal banana vibrating screen design represents the intelligence and efficiency of the screening process. From the input end to the output end, the inclination angle of the screen surface is precisely calculated and gradually decreases. This design ensures that the materials obtain the maximum acceleration at the input end, spreading and layering quickly, allowing a large amount of fine particles to pass through the screen immediately; while at the output end, the gentle angle slows down the material flow rate, providing sufficient screening opportunities for the remaining fine particles. This unique movement trajectory significantly improves the screening efficiency and unit area processing capacity of the entire machine, especially suitable for scenarios of high processing capacity and multi-stage size separation of raw coal classification.

 

 

 

coal banana vibrating screen adopts multi-slope screen deck, which has high handling capacity and high screening efficiency.

 

 coal banana vibrating screen consists of several sections of screen deck, and the angle of inclination of screen deck gradually decreases from the feeding end to the discharging end.

 When the coal banana vibrating screen operation, the feeding end screen surface due to the larger angle, the material into the screen surface with a large acceleration rapidly forward and rapid stratification, materials smaller than the screen holes is in full contact with the screen surface and smooth through the screen.

 The angle of the screen surface at the discharge end is gentle, and the material movement speed gradually slows down, fully allowing the remaining materials smaller than the screen hole to pass through the screen, greatly improving the screening efficiency.

 The coal banana vibrating screen can meet specific application requirements by changing the inclination angle of the multi-slope screen deck. The angle of the multi-slope screen deck determines the running speed of the material on the screen deck and the handling capacity of the banana screen.

 

 

 

 

 

 

 

01/  Unique Screen Surface Design

Our coal banana vibrating screen adopts a unique banana-shaped multi-stage screen surface design. The inclination angle decreases gradually from the feed end to the discharge end. The large inclination angle at the feed end enables the materials to spread quickly and be efficiently stratified, with fine particles quickly passing through the screen; the small inclination angle at the discharge end reduces the flow rate, allowing the remaining fine particles to be fully screened. This optimized design significantly improves the screening efficiency and unit processing capacity compared to traditional linear screens, and is particularly suitable for efficient classification of large-flow, multi-grain-size raw coal operations.

 

02/ Super Large Processing Capacity

To meet the high production requirements of modern large-scale coal preparation plants, the coal banana vibrating screen we designed has outstanding processing capabilities. The single machine processing capacity can reach over 420 tons per hour. The wide double-layer screen surface (such as 3.6 meters wide and 7.3 meters long) provides sufficient screening area and space for the materials, enabling it to handle the continuous high-flow materials transferred from the raw coal bunker with ease. It is the core equipment that ensures the efficient and stable operation of the front end of the coal preparation system and enables the annual processing capacity to reach millions of tons.

 

03/ Outstanding Screening Accuracy

We ensure that the coal banana vibrating screen has excellent screening accuracy. The upper layer screening efficiency is ≥ 95%, and the lower layer is ≥ 90%. This is attributed to precise dynamic calculations, high-quality screen plates, and stable vibration parameters. This equipment can efficiently separate 0-300mm wide-grained raw coal into target particle sizes (such as 300-50mm, 50-25mm, -25mm), providing ideal feeding conditions for subsequent intelligent dry selection or air separation processes, and directly increasing the yield of lump coal and overall economic benefits.

 

04/ Sturdy And Durable Structure

The core components of the coal banana vibrating screen, such as the side plates and cross beams, are all made of high-quality low-alloy high-strength steel through overall laser cutting and no welding seams are used. Strengthening plates and protective plates are scientifically arranged in key stressed areas to evenly distribute the load and effectively resist long-term alternating stress and impact. The overall design service life of the machine can reach more than 8 years, and the lifespan of the exciter beam and other core components is not less than 33,600 hours, ensuring long-term and reliable operation under harsh working conditions in coal mines.

 

05/ Advanced Riveting Technology

To address the common problems of stress concentration and fatigue cracking in the welding of sieve frames, our coal banana vibrating screen innovatively adopts a high-strength ring groove riveting process at the core connection points. All reinforcing components and the main side plate are connected by riveting, completely eliminating welding stress and heat affected zones. This fundamentally eliminates the risk of cracking and significantly enhances the overall rigidity and fatigue life of the screen body, ensuring the structural safety of the equipment.

 

06/ Modular screen plate
Our coal banana vibrating screen adopts standard-sized polyurethane frame and track seat screen plates, with a modular design. It is highly versatile and supports quick disassembly and assembly. The screen plate is inserted into the track and fixed by polyurethane side pressure strips and wedges. This design makes the replacement of the screen plates for the entire screening machine extremely efficient. Usually, it only requires two workers to complete the task within 30 minutes, significantly reducing maintenance downtime and lowering operating costs.
