The screen surface of the flip flop screening machine is usually very spacious, with an area of several tens of square meters, capable of handling a large amount of raw materials. Moreover, it has a high screening efficiency and can complete a large number of screening tasks in a short period of time. Driven by an electric motor, this equipment operates stably with extremely low noise, and the operation and maintenance are convenient for users. In addition, the large-scale expandable screen mesh can be customized according to specific production requirements to ensure that it can meet various production demands.

The flip flop screening machine is a dual-mass vibration system. It uses polyurethane rubber as the screen surface and employs block eccentricity to provide excitation force for the screen body, causing the screen body to undergo linear motion. The efficient polyurethane screen plate is installed on the fixed crossbeam and the floating frame. Due to the interlaced movement of the screen body crossbeam and the floating frame, the screen plate is tightened and relaxed, resulting in a breathing phenomenon of the sieve holes. The screen surface achieves a fluctuating acceleration of up to 50 G, forcing the wet and sticky materials to separate rapidly and pass through the screen efficiently.

Flip Flop Screening Machine 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.

EXCT Flip Flop Screening Machine Vibration Exciter

01/ Outstanding Performance

The oscillating screen has an extremely large screening area and outstanding processing capacity. The vibration intensity of the screen surface reaches 30 to 50G, and the amplitude can reach 18mm. Combined with the micro-deformation design of the high elasticity screen mesh during the oscillating motion, it can effectively disperse sticky and fine materials, reduce blockages, and improve screening efficiency.

02/ Efficient Resonance

The equipment adopts the dual-mass resonance principle. Compared with traditional screening equipment, it has the advantages of lower energy consumption, longer screen machine lifespan, and higher screening efficiency. Through professional software simulation of material operation, it can precisely match the optimal vibration parameters and scientifically avoid operational risks.

03/ Reliable Design

The sieve frame adopts a heavy-duty and high-strength structure, ensuring stable operation and strong load-bearing capacity. The large-area feed sieve plate can withstand the initial impact of the materials and achieve 100% utilization of the sieve surface.

04/ Easy To Assemble And Disassemble

The box-type exciter can provide high-amplitude vibration and is easy to assemble and disassemble. The snap-fit screen mesh has high elasticity and a long service life, and is easy to replace. The application of the thin oil lubrication system reduces maintenance requirements and shortens downtime.

05/ Green And Environmentally Friendly

This equipment consumes significantly less energy than traditional screening machines under the same processing capacity, achieving a green operation. By using a more rigid and more capable composite spring, the running noise is reduced at its source. The equipment can also be equipped with a fully enclosed dust-proof cover design, effectively preventing dust from spilling out during the screening process and meeting environmental emission standards.

Flip Flop Screening Machine 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 flop screening machine 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 flop screening machine will resolve this industry issue and promote its development.
