In scenarios such as coal processing plants, metallurgical workshops, or building material production lines, wet and sticky materials (such as coal sludge, ore powder, and wet sand) are continuously fed into vibrating screens. However, traditional screening equipment often encounter a troublesome problem - screen holes getting clogged. The materials get stuck in the screen holes, causing a significant drop in screening efficiency, frequent cleaning, and the production falling into a low-efficiency and high-cost quagmire.
To address this issue, we have developed and produced the mechanical flip flow screen. It is widely used in industries such as coal, mining, metallurgy, power, building materials, and environmental protection due to its high screening efficiency, large processing capacity, non-clogging screen holes, and strong adaptability.
Flip Flow Screen Working Principle
You can imagine it as shaking a blanket, not lifting the entire frame and shaking it, but by holding the two sides of the blanket with your hands, pulling and releasing, causing the blanket itself to undergo intense wave-like motion.
This alternating motion of pulling and releasing enables the materials on the screen mesh to obtain extremely high vertical acceleration (up to 30-50G), thus being violently thrown up and shaken apart, the material clumps adhering to the screen mesh also completely disperse, and the particles stuck in the sieve holes are effectively ejected.

Flip Flow Screen Structure
Flip Flow Screen Details
Flip Flow Screen Characteristics
Strong Anti-clogging Capacity
This is the primary reason for the emergence of the flip flow screen. The intense tension and relaxation movements enable it to handle wet and sticky materials that ordinary vibrating screens cannot handle, thus solving the problem of screen mesh clogging.
Extremely High Screening Efficiency
For materials that are difficult to screen, the screening efficiency is usually over 30% higher than that of ordinary vibrating screens, effectively separating out products of the desired particle size.
High Elasticity Screen Mesh
The screen mesh is made of high elasticity and high flexibility polyurethane material. It can be significantly stretched, shaken and rebounded. It has the characteristics of being fatigue-resistant, stretch-resistant, and having a stable lifespan under harsh and wet working conditions.
Smooth Operation
Although the screen mesh moves vigorously, the main body of the screen box remains almost stationary. This results in very little impact on the dynamic load of the foundation or floor, which is conducive to installation at the upper floors of the factory building, and also leads to lower operating noise.
Fully Enclosed & Environmentally Friendly Design
The equipment can be equipped with a dust-proof cover as a whole, effectively preventing the leakage of dust. At the same time, when handling materials with high moisture content and prone to adhesion, such as construction waste, the full enclosure can prevent the diffusion of leachate and reduce the loss of material splashing.
Suitable For Extreme Conditions
Designed specifically for highly moisture-containing materials such as clean coal with high moisture content, coal sludge, clay, sludge, and domestic waste.

Flip Fow Screen Applications
The flip flow screen is mainly applied in industrial scenarios where the screening efficiency is highly demanded and the material properties are harsh:
| Coal Industry |
This is the largest application field for the flip flow screen, used for the dehydration and classification of fine coal, medium coal, and coal sludge with high moisture content (>10%). |
|
Mineral Processing Industry |
Classification, dewatering, and desliming in wet selection processes of iron ore, bauxite, copper ore, etc. |
|
Building Materials Industry |
Wet screening and classification of sand and gravel, dewatering of quartz sand, screening of limestone. |
|
Environmental Protection Industry |
Sludge treatment, solid waste screening, recycled aggregate processing. |
|
Chemical & Food Industry |
Certain process steps that require handling wet and sticky powders or particles. |

Flip Fow Screen On Site
Applications in the coal chemical industry : It resolves technical challenges in fine screening for industries with ultra-high - capacity, such as the coal chemical industry, where the screening radius is 12mm. In cases where over 90% of the material is retained on the screen in ultra-high-capacity screening, it has been applied at Henan Yima Gasification and Xinjiang Guanghui New Energy, successfully solving screening tasks that vibratory flip flow screens couldn't accomplish.
Applications in the coal industry: It solves the technical challenges of screening fine, moist, and sticky coal particles. With a screening range as small as 3mm, it has been applied at State energy Group's Wanli No.1 Mine and Lijiahao Coal Mine. This equipment is capable of handling sticky and fine coal particles, offering a high screening efficiency and precision that post-screening equipment cannot match.
Other industrial applications: In industries like aggregates and nonferrous metals, especially in the aggregates industry, screening 3 - 5mm moist and sticky materials remains a challenge. The application of mechanical flip flow screens will resolve this industry issue and promote its development.
