Material: EPS, EPP, PE, PU, PP and other foam particles
What is Foam Screening Machine?
Foam Screening Machine is a vibration device used for grading and removing impurities of various foam materials such as EPS (polystyrene), EVA (ethylene-vinyl acetate), PP (polypropylene), PU (polyurethane), etc. The vibration motor drives the screen surface to produce three-dimensional movement, so that the foam is graded according to the particle size or impurities in the foam are removed. It can screen 10-500 mesh (corresponding to particle size 2-0.028mm) foam, while maintaining more than 99% particle integrity, and the output can reach 5 tons. The material is stainless steel 304/316L, which is corrosion-resistant and anti-static. The screen has 1-5 layers to choose from, which can accurately separate 2-6 different specifications of foam.
In the fields of foam recycling, food packaging, medical microsphere production, etc., traditional screening equipment often faces problems such as high foam breakage rate, electrostatic adsorption blocking, and low fine particle grading efficiency. Foam Screening Machine can effectively solve the screening problems of light foam particles, easy electrostatic adsorption, and irregular shape by optimizing vibration parameters and screen structure.
What types of Foam Screening Machine are there?
Foam Screening Machine can be divided into three types: standard type, stainless steel type, and ultrasonic type. You can choose according to the characteristics of the foam and the application industry.
Standard Foam Screening Machine: Suitable for dry screening of ordinary EPS and EVA foam particles, with a screening mesh of 20-200 mesh and a processing capacity of 1-5 tons/hour
Stainless steel Foam Screening Machine: Made of 304/316L stainless steel, it is clean and hygienic and suitable for screening food-grade foam and medical packaging foam
Ultrasonic Foam Screening Machine: With the addition of an ultrasonic device, it can screen PU foam and ultra-fine foam powder that are prone to electrostatic adsorption, with a mesh of up to 623 mesh
What are the advantages of Foam Screening Machine?
Foam Screening Machine can effectively solve the problems of clogging, crushing, electrostatic adsorption, low screening efficiency, etc. that occur when traditional equipment screens foam particles. The specific advantages are as follows:
High-efficiency screening: Adopting the principle of three-dimensional vibration, the material moves in an involute motion on the screen surface, with a screening efficiency of up to 90-95%, and a processing capacity 30% higher than that of ordinary vibrating screens
No clogging: Foam particles are prone to electrostatic adsorption, and the clogging rate of traditional screening machines is as high as 30%. Foam Screening Machine is equipped with a bouncing ball, a drum brush and an ultrasonic triple net cleaning device to ensure continuous production without clogging.
Material breakage: The low-speed swing design (only 1/3 of the speed of ordinary vibrating screens) combined with the involute motion trajectory protects the integrity of brittle foam particles, and the breakage rate is reduced to less than 0.5%.
Precise grading: It can accurately screen foam particles of 20-500 mesh (0.028mm-0.85mm), and divide the materials into 2-6 different particle sizes, with an accuracy of 95%-99%, meeting the strict requirements of different industries for foam particle size
