The flip flow screen is a highly efficient screening equipment that utilizes mechanical drive to achieve high-frequency flip and flop movements of the elastic screen mesh. It is specifically designed to handle moist, sticky, clumping-prone, or high-density materials. Its core advantage lies in the combination of mechanical structure drive and elastic screen mesh technology. The constant flexing action of the elastic screen plate prevents particle adhesion, while the elongation of the screen plate causes a slight change in the screen mesh opening in the tension direction, which can be described as the "breathing" of the screen mesh. Combined with high acceleration forces, this prevents particles close to the screen mesh size from clogging the mesh.
Applications include wet recycled materials as well as high moisture and viscous ash, mineral and clay-based materials, or industries such as coal preparation plants, coal chemicals, fertilizer plants, construction aggregates, and non-ferrous metals. The size of the processed materials usually ranges from 0 to 100 mm
How Flip Flow Screens Work?
The mechanical flip flow screen is also known as the crank and connecting rod type flip flow screen.
The screen body is mainly composed of inner and outer screen frames. The inner screen frame is placed on the frame via a rubber shock absorber spring, while the outer screen frame is suspended on the inner screen frame by a leaf spring (glass fiber). Under the drive of external force, the inner and outer screen frames move relatively parallelly.
The movement of the screen frames is driven by the motor to rotate the eccentric shaft. The eccentric shaft, through the thrust rod spring, continuously pushes and pulls the outer screen frame, causing a reverse linear motion between the inner and outer screen frames. Thus, the crossbeam installed on the screen frames can drive the flexible screen plate to perform alternating relaxation and tensioning movements. The materials on the screen surface will undergo a "bounce-up, fall-down, bounce-up" cyclic harmonic motion, thereby completing the grading operation of layer-by-layer screening of the materials.
Flip Flow Screen Structure
The screening machine mainly consists of a combined screening body (screen frame, flexible screen plate, crank transmission device, end transmission, motor, motor support, screening body support, vibration-damping springs, sealing cover, etc.).
The screen frame is connected by enhanced carbon fiber elastic elements provided by a German manufacturer. These elastic elements remain intact even after millions of reciprocating deflections.
The reciprocating distance between the components is determined by the inherent characteristics of the equipment and does not change with the load size of the screening machine. Therefore, the stability of this type of screening machine is an unparalleled advantage compared to other types of flip flow screens

Flip Flow ScreenFeatures
01/ The Solution For Screening Difficult Materials
The eccentric shaft drags the inner and outer screen frames for forced movement,produces relative motion in the two screen frames,andproduces a trampoline effect"in the screen to achieve high efficiency screening.
02/ Low Operating Costs
Due to its lightweight structure,it only requires and consumes low energy to drive It can protect the environment and reduce operating costs.It can be installed and used on existing technical facilities,thereby reducing investment costs.
03/ High Screening Efficiency
The screen design and operating principle of the flip flow screen allow it to handle more material than traditional screening equipment in the same area,improving the overall production efficiency.
04/ Strong Reliability
The speed of the mechanical flip flow screen is lower than that of the traditional screen machine (usually below 600 rpm).The low speed helps to reduce the vibration and mechanical load generated during the operation of the equipment,thus extending the service life of the equipment.
05/ No Blocking Material
Constant deflection means that the screen plate always flexes and recovers in an elastic manner during operation,and this action helps prevent material from adhering to the sieve.
06/ No Impact
The rubber spring supporting the screen machine only bears the weight of the screen machine in the vertical direction of work,and the installation inclination direction bears the inertial force of the screen machine,lead to the equipment having no vertical impact on the foundation,reducing the bearing requirements of the foundation and reducing additional investment.
