POWERBELT FAQ
- Which is the difference between POWERBELT and AutoScreen?
As far as general logics and operation, there is no difference between them. The actual difference lies in the higher screen advance speed and performance evenness, which allow POWERBELT to process highly contaminated materials – it was not possible with AutoScreen – such as post industrial ones.
- Does any material leakage occur during operation?
No, there is none, regardless of the material.
- Why there is no material leakage?
Sealing is produced by the material itself. Thanks to the entry and exit cooling sections, the solidified material prevents any leak.
- Which are POWERBELT advantages?
The main advantage is the increase in screen advance speed, which allow highly contaminated materials to be processed, such as post industrial ones. Furthermore, POWERBELT is fully automatic, i.e. there is no need for any operator assistance, except for screen roll replacement. A further important advantage is process stability, such as irrelevant pressure fade during screen changing. Last but not least, having no motor or moving mechanical parts, POWERBELT does not require any special maintenance interventions, except for screen roll replacement.
- How about water consumption; which kind of water is required?
A close circuit with cooling system is recommended. In the event a chiller is not provided, water consumption will be proportional to operating temperatures, process materials and POWERBELT dimensions. Nonetheless, water consumption is comprised between 0.5l and 2l per minute, at room temperature.
- Which are the admitted operating pressures?
POWERBELT operates within the following pressure range: 35-700bar (500-10,000psi). Minimum pressure values depend on the characteristics of the processed materials.
- Which are the available dimensions?
The breaker measures 35mm min, up to 200mm max (from 1-1/4" to 8").
- Which are the admitted process temperatures?
POWERBELT, in its standard version, works at 350°C (662°F) max.
- Which hourly capacity can be reached?
The hourly capacity indicated below is for illustrative purpose only, as this value depends on several variables, such as process conditions, materials, contamination and filtering level. Further to the above, it is reasonable to say that the POWERBELT hourly capacity is up to 2500kg/h (5500 pounds per hour).
- How long does a screen last?
Screen life can be determined on the basis of screen changing rate.
- Which maintenance operations are required?
Having no motor or moving mechanical parts, POWERBELT does not require any special maintenance interventions, except for screen replacement.
- Which spare parts must be available?
Filtering screen only.
- Which materials may be used?
Any and all thermoplastic materials may be processed with POWERBELT. We are glad to remind you that we offer a trial at our lab, even with your material, to let you specifically check the different operating parameters.
- Which is the admitted material contamination level?
The contamination level can only be generically determined. We can say that POWERBELT is capable of processing contaminated materials, e.g. post industrial ones. POWERBELT cannot manage extremely contaminated materials, such as urban or private post consumer materials.
- Which are the suitable applications?
Substantially, all and any applications in plastics extrusion.
- When POWERBELT is not recommended?
POWERBELT cannot be used with extremely contaminated materials, such as urban or private post consumer materials.
- Do I need the control panel?
Yes, the control panel is essential for POWERBELT operation.
- May I achieve heating control with my extruder?
Yes, all heating zones, except for screen advance controller heating, may be disabled in order to use the control zones already available on your extruder control panel.
- Is it better to set a time control or a pressure control?
Generally, control may be set as time control, pressure control, time and pressure control (the so-called dual control) or manual mode. The pressure control maximises screen duration.
