In the fields of coal washing, metal ore classification and sand and gravel aggregate processing, the banana vibrating screen for mining has become the core equipment for efficient separation of fine-grained materials with its unique “multi-stage inclination” structure and modular design. It can not only accurately complete material classification, but also simultaneously achieve media removal (medium removal) and mud removal (mud removal). It has the characteristics of high reliability, low energy consumption and long life, and is particularly suitable for the industrial processing needs of large and medium-sized coal and non-coal materials (0-300mm) with high fine particle content.
Core functions: classification + medium removal + desludging integration
Multi-stage classification, double efficiency
The banana vibrating screen adopts a unique zigzag screen surface design. Through the combination of 3 to 5 screen plates with different inclinations, the material flow rate is gradually reduced and the fine particle screening time is prolonged. For 0-300mm mixed materials, coarse, medium and fine products can be separated at one time, and the screening efficiency is more than 90%, which is 15% to 20% higher than the traditional linear
Efficient removal of media and mud
De-mudification:
In the heavy medium coal preparation process, the banana vibrating screen quickly separates the magnetic medium and clean coal through high-frequency vibration and screen surface washing system, and the medium recovery rate exceeds 98%.
For wet and sticky materials with high mud content, the elastic surface of the polyurethane screen plate can reduce clogging, and cooperate with the high-pressure water spray device to peel off the mud film and improve the product purity.
Structural innovation: lightweight, high reliability, maintenance-free
Double sieve plates, suitable for complex working conditions
Steel structure screen plate:
Made of high-strength wear-resistant steel (such as Hardox450), suitable for handling large-particle, high-impact dry materials, with a service life of up to 10,000 hours.
All-polyurethane screen plate:
One-piece casting, with an opening rate of 30%~60%, elastic and anti-clogging, suitable for wet and sticky fine-grained materials (such as coal slime and tailings), and the noise reduction effect is improved by 30%.
ZDQ series exciter: intelligent drive, stable and low consumption
Dual-axis self-synchronous vibration technology, adjustable excitation force 30-150kN, processing capacity covers 50-800t/h.
Fully enclosed oil bath lubrication + labyrinth seal, achieving “zero maintenance” operation, life span exceeds 20,000 hours.
Frequency conversion control accurately adjusts the amplitude to avoid material accumulation or excessive crushing.
Lightweight design, eliminating stress and resonance
Finite element structure optimization:
Through CAE simulation analysis, the stress distribution of the screen frame is optimized, the weak points are eliminated, and the weight of the whole machine is reduced by 20%.
Weldless side panels:
Imported HUCK bolts are used for hydraulic tensioning assembly to avoid welding deformation and residual stress, and the fatigue strength is increased by 50%.
Special round beam:
Lightweight high-strength steel pipe + polyurethane spray surface, erosion and corrosion resistance, and the beam life is extended by 3 times.
Performance advantages: low consumption, quiet, long life
Energy saving and environmental protection:
The power of the whole machine is 25% lower than that of the traditional screen machine, and the noise is ≤85dB (1 meter distance).
Anti-corrosion and durable:
The whole machine is sandblasted and painted + epoxy zinc-based coating, with waterproof sealing on the joint surface, suitable for high temperature, humidity and dust environment.
Maintenance-free operation:
Modular design of exciter, screen plate, etc., supports quick replacement, and reduces annual maintenance cost by 60%.
Typical application scenarios
Coal washing plant
Raw coal classification (0-300mm), removal of gangue and coal slime.
Removal of magnetite powder in heavy medium system, recycling of circulating medium.
Metal mines
Dehydration and desliming of iron ore and copper ore tailings to improve the grade of concentrate.
Grading and purification of non-metallic minerals such as quartz sand and feldspar.
Building aggregate line
Removal of fine powder and classification of finished products in wet process of machine-made sand.
The banana vibrating screen for mining has redefined the performance standards of modern screening equipment through the deep integration of lightweight structure, wear-resistant materials and intelligent vibration. Its composite functions of classification, de-intermediation and desludging, combined with maintenance-free design and ultra-long service life, not only greatly reduce operating costs, but also provide reliable support for the green and intelligent upgrade of coal and mineral processing technology. In the future, with the continuous breakthroughs in polyurethane materials and vibration control algorithms, the banana vibrating screen will demonstrate its high efficiency value in more complex working conditions.
