In order to filter contaminations effectively and efficiently out of plastics waste, in case of the BritAS filter, the filter fabric is fully-automatically changed. Thus, the regranulate quality remains constantly high and the contamination is discharged out of the machine with a very low loss of melt. By an intermediate container for the melt, the upstream extruder is permanently running.
The ABMF filter can be retrofitted from discontinuous to continuous.
1.
Continuous melt flow through the screen.
Reaching the adjustable limit pressure in front of the screen:
The fully-automatic screen change is started.
2.
The valve will be closed – the space in front of the screen is unpressurized.
The accumulator piston is moved downwards by the plastics melt and the buffer volume is increased.
The wedges are opened parallel and the screen belt fixing is released.
3.
Via transport rolls, the screen belt is guided until there is clean screen mesh in the filter zone again.
4.
The wedges will be closed – the screen belt is fixed and sealed again.
5.
The valve will be opened – there is access again for the melt to the filter zone.
6.
With an adjustable speed, the accumulator piston is
moving upwards and the material quantity, which was accumulated during the screen change is dosed. If the
accumulator piston has reached the upper end position, the screen change procedure is finished.
Automated. Fully-automatic filtration.
The filter mechanics combined with the control provide for a fully-automatic,practical and cost-saving operation.
Clean. Very high filtration fineness.
Up to three filter belts can simultaneously be used. This allows an exact adjustment of different filter screen finenesses.
Permanent. Extruder operation during screen belt feed.
By storing temporarily the plastics melt, also during the screen feed, the extruder continues running and guarantees high process reliability.
Effective. Very high throughput rates.
The new support plate design – consisting of grid and die plate – guarantees higher throughput, thus less pressure generation and more gentle processing.
Perfect. Homogeneity of the plastics melt.
The optimized flow channel improves the melt flow considerably again without material stress.
Efficient. Very low operating costs
Besides the automatic operation of the filter with high plastics throughput, the use of filter belts with dutch weave meshes ensures low operating costs at high output.
BritAS uses simulations as basis for product optimizations – example optimization grid and die plate
Suitable for post-consumer and post-industrial plastics waste and agricultural film.
Depending on the customer requirement, different materials, dimensions, weaves and tensile stren possible.
