Flip Flow Screen

The flip-flow screen is a flexible polyurethane screen that operates on the "flip flow" principle, alternately tensioning and relaxing. Especially suitable for screening sticky, wet and other difficult materials.

Working Principle

How Flip Flow Screen Work

Mechanical flip-flow screen is also called crank-connecting rod flip-flow screen. The screen body is mainly composed of inner and outer screen frames, in which the inner screen frame is placed on the frame through rubber shock-absorbing springs, and the outer screen frame is suspended on the inner screen frame through leaf springs (fiberglass). Driven by external forces, the inner and outer screen frames move relatively parallel. The movement of the screen frame is driven by the motor to rotate the eccentric shaft, and the eccentric shaft will continuously push and pull the outer screen frame through the push rod spring, so that the inner and outer screen frames produce reverse linear motion. In this way, the crossbeam installed on the screen frame can drive the flexible screen plate to do alternating relaxation and tensioning movements, and the material on the screen surface will do a cyclic simple harmonic motion of "bouncing up, falling down, and bouncing up again", thereby completing the grading operation of material stratification and screening.

Features and Benefits

Flip Fow Screen Features

Flip flow screen is dedicated to the screening of wet viscous materials, widely used in coal preparation plants, coal chemical industry, fertilizer Construction aggregates, non-ferrous metals and other industries

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, and produces a "trampoline effect" in the screen to achieve high efficiency screening.

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.

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.

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.

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.

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.

Frequently asked questions

Flip Flow Screen FAQ

Below you'll find answers to the questions we get asked the most about Flip Flow Screen.

Why is the efficiency of flip flow screen continuously stable?

The relative amplitude of the inner and outer screen frames depends on the eccentricity and is not affected by external factors such as materials,so the amplitude is constant.

Why does the flip flow screen not blocking easily?

The constant flexing of the elastic screen prevents particles from sticking. The elongation of the screen causes a slight change in the screen opening in the tensioning direction. This can be described as the "breathing" of the screen. In combination with the high acceleration forces, this prevents particles close to the screen size from blocking the screen.

Why is the flip flwo screen more reliable?

Compared with the traditional screening machine,the mechanical relaxation screen has the characteristics of running at a speed lower than 600 rpm,and the screening machine itself only generates stress at an acceleration of about 2-3g.Therefore,the screening machine itself will have higher reliability.Theoretical design and practical test have proved that the same type of products have achieved industrial durability verification.
