When extruding plastics, a contamination-free plastic melt is desired. Since contamination affects the quality of the product and impedes the operating process, it is essential to ensure a perfect filtration process and improve the quality of the plastic melt by using a melt filter. A perfect filtration performance without any deterioration of the melt quality is possible with the well-proven DEAO Screen Changers, a large variety of which is incorporated into plastic extrusion machines
Screen Diameter(mm) | Heating power(Kw) | Suitable Materials (Mpa) | Output(Kg/h) | |
DHB-70 | Φ70 | 4.4 | ≤50 | 60-250 |
DHB-100 | Φ100 | 6.8 | ≤50 | 110-400 |
DHB-120 | Φ120 | 8.6 | ≤50 | 140-550 |
DHB-150 | Φ150 | 9.8 | ≤50 | 200-800 |
DHB-170 | Φ170 | 9.8 | ≤50 | 300-1000 |
DHB-200 | Φ200 | 11.6 | ≤50 | 400-1200 |
DHB-250 | Φ250 | 16.4 | ≤50 | 600-1800 |
DHB-300 | Φ300 | 16.4 | ≤50 | 800-2500 |
1,To move from the filtering screen in use to the clean screen takes only a minimum time, less than 2 seconds
2,Single plate screen changer can be mounted both horizontally and vertically without affecting performance
3,Several single plate screen changers can be controlled by the same hydraulic unit, resulting in large savings and maximum use of space
4,1)The safety blocking system of the doors and the hydraulic unit protects from the movements of the plates and from accidental opening during maintenance
2)The block of the accumulator prevents the hydraulic unit to exceed the adjusted maximum pressure
3)guarantee a perfect seal during the sliding of the plates
