However, during the actual screening process, due to the fact that the extracted raw coal has a certain amount of external moisture, the fine coal tends to stick together and form clumps. The wet coal clumps are not promptly disintegrated, which easily leads to the formation of mismatched substances and worsens the screening process. To increase the collision and disintegration degree of wet coal clumps on the flip flow screen, and to improve the screening efficiency, we independently developed and manufactured this flip flow screen for coal.

It uses high-elastic mesh and high-frequency flipping technology, which can quickly stretch and relax the mesh, effectively preventing fine materials from accumulating at the corners of the mesh or getting blocked in the mesh holes. With this unique operation method, EXCT's flip flow screen can screen out extremely small particle sizes. It is not only applied in the coal industry, but also widely used in various fields such as dry screening of construction waste, crushed stones, sand, compost, wood chips, recycled glass, carpet fibers, waste residue, and recycled electronic components.

The flip flow screen generates power through a vibrator, which is transmitted to the screen mesh on the screen box frame, thereby providing the material with a projectile acceleration of 30-50g. This is beneficial for fine coal particles to pass through the screen and complete the screening process. Therefore, it is widely used in deep grading of coal.

Flip Flow Screen For Coal Vibration Exciter

Adopt the ZYQX series high-efficiency gear transmission oil-lubricated box-type vibration exciter independently developed and manufactured by our company;

The vibration exciter is equipped with imported SKF large clearance bearings specially designed for vibration machinery;

The vibration exciter uses high-precision heavy-duty helical gears, splash lubrication, and a magnetic drain plug to absorb iron filings in the lubricating oil;

The gas and heat in the vibration exciter can be freely exchanged through the special seal at the shaft end, and the lubricating oil will not leak out. This specially designed structure can ensure that coal dust or other foreign matter cannot enter the vibration exciter;

The eccentric torque of the vibration exciter eccentric wheel can be adjusted to meet the different amplitude requirements of the material for the equipment.

Strong Anti-Clogging Capacity

The high-frequency expansion and contraction movement of the screen surface can impart a 50G acceleration to the materials, effectively dislodging adhered fine particles and ensuring that the screen holes are not clogged. It is the most effective screening method for processing sticky and wet coal with an external moisture content of 8% - 14%.

Achieving Deep Screening

It is possible to directly conduct dry screening of raw coal at 6mm or even 3mm particle sizes, separating a large amount of qualified fine coal as products in advance. This significantly reduces the amount of coal slime entering the washing system, lowering the load and processing costs of the coal slime water system.

High Processing Capacity

The screen surface inclination can be adjusted (often using multiple inclined sections similar to a banana screen), with fast material flow rate and large processing volume per unit area.

High Screening Efficiency

The screening efficiency for fine particle sizes (such as 6mm, 3mm) is high, generally reaching over 80%, and can be optimized to over 92%.

Excellent Wear Resistance

The high elasticity polyurethane sieve plate has extremely good wear resistance, with a service life exceeding 4,000 hours. The sieve plate is installed by pressing in and pulling out, making it convenient for sieve plate replacement and maintenance.

Low Power Consumption

Compared with traditional screening machinery, it has a higher vibration intensity but the dynamic load transmitted to the foundation has advantages. Among them, the vibration motor-driven type has lower power consumption per unit area.

Flip Flow Screen For Coal 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 screen for coal 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 screen for coal will resolve this industry issue and promote its development.
