High to very high output range 450 - 2400 kg/h (LDPE)
> High filter fineness possible
Up to two filter bands can be used at the same time depending on the filtration requirements. It is thus possible to tune the accurate filter fineness - 70μm to 950μm
The large filter area ensures the gentlest processing with only a slight increase in melt pressure. This results in higher quality pellets with better quality characteristics.
> Extruder operation during filter band feed
The filer band feed can only be done in the decompressed state. In order not to interrupt the operation of the extruder during the filter band feed, the plastic melt is "stored" in a buffer. This prevents manual process interventions and increases process stability.
The intermidiate storage of material in the melt buffer is automatically activated by the contro system according to preset parameters. This is a convenient solution to ensure a consistently high quality.
> Very high throughput rates
In the filter zone, the filter band is supported by a support plate facing the direction of the extrusion. This protects the filter from damage and ensures a safe operation.
The support plate has sufficiently large through-flow areas to keep the increase in melt pressure low. With this system, very high throughputs are permanently and profitably possible.
> Regular filter area renewal
The working principle of the band filter triggers a renewal of the filter area during the band feed. Thus, no contamination is left behind in the filter system. This ensures a consistently high melt quality and supports process stability.
The filter area renewal by the automatic band feed is easy and convenient.
> Fully automated filtration
The interaction of filter mechanics and the control system allows for fully automated operation and thus makes filtration easier and minimizes costs.
The filter band completely removes the filtered contaminants from the filter area, which increases pellet quality for a profitable resale.
> Very low operating costs
When operating filter systems, the focus should be on removing contaminants from the melt and preventing melt loss. The band melt filter collects contaminants in the filter band catching only tiny melt amounts - this ensures a very high yield.
The utilization of low-cost filter bands with Dutch weave mesh further reduces operating costs.
