Foam particle straight screen

Foam particle straight screen is a special device for screening foam particles. It is mainly used to classify foam particles of different particle sizes or remove impurities. It is usually suitable for screening materials such as foam plastics, EPS (expandable polystyrene), EPE (polyethylene foam), etc. It uses a special screen structure and vibration method to efficiently separate solid particles, liquids and gases in the foam.

How does the foam particle straight screen work?

Vibration is generated by a vibration motor or ultrasonic vibrator, and the material moves on the screen based on the screening effect of the screen and the inertial force generated by the vibration. The material enters the screen box through the feed port, and is subjected to the vibration in the screen box, causing the foam to break, the solid particles to be trapped by the screen, and the liquid and gas to be discharged through the screen. Smaller particles pass through the screen and fall into the lower layer, while larger particles move forward along the surface of the screen and are finally discharged from the discharge port.

Structural features of the foam particle straight screen

1. Screen box: The screen box is usually made of stainless steel, which is corrosion-resistant and easy to clean. There are multiple layers of screens in the screen box, and the aperture of each layer of screens is different, which can achieve multi-level screening.

2. Vibration motor: Provides vibration power to make the screen box vibrate, so that the material moves on the screen surface.

3. Screen: The screen material is diverse, and different screen materials can be selected according to the characteristics of the material, such as stainless steel, nylon, etc.

4. Discharge port: There are solid material discharge port, liquid discharge port and gas discharge port respectively.

What are the advantages of the foam particle straight screen?

1. Solve the problem of electrostatic adsorption of foam particles: Foam particles are prone to generate static electricity during the screening process, causing the particles to be adsorbed on the screen or the inner wall of the equipment, affecting the screening efficiency. The high-frequency vibration of the ultrasonic vibrator destroys the electrostatic adsorption force between the particles and the screen, allowing the particles to pass through the screen smoothly.

2. Deal with the problem of screen blockage: Foam particles are irregular in shape and are easily stuck in the screen holes, causing the screen to be blocked, affecting the screening efficiency. The high-frequency vibration of the foam particle straight screen can effectively prevent the particles from getting stuck in the screen holes and keep the screen unobstructed.

3. Avoid the problem of uneven particle size of foam particles: The particle size distribution of foam particles is uneven, which may lead to unsatisfactory screening effect. By adjusting the frequency and amplitude of the vibration motor, it can adapt to the screening needs of different particle sizes. Configure a multi-layer screen to divide the particles into multiple grades according to the particle size to ensure the screening accuracy.

4. Avoid the problem of impurities mixing: Dust, metal fragments, agglomerates and other impurities may be mixed into the foam particles, affecting the product quality. Use a coarse screen to remove large particle impurities and a fine screen to remove small particle impurities. Install a magnetic separation device at the feed port or during the screening process to remove metal impurities.

5. Solve the problem of particle breakage: During the screening process, foam particles may be broken due to vibration or collision, affecting product quality. Use low-amplitude, high-frequency vibration to reduce the impact on particles. Install a buffer device inside the equipment to reduce collisions between particles.

6. Insufficient processing capacity: Traditional screening equipment has limited processing capacity and cannot meet the needs of large-scale production. Use high-power vibration motors to improve screening efficiency, and choose a large-size screen to increase the single processing capacity. The equipment supports continuous feeding and discharging to meet the needs of large-scale production.
