1 ABMF 570 ABMF 750 ABMF 1050 ABMF 1600 ABMF-C ABMF-BV Automatic Belt Melt Filter Constant regranulate quality due to fully-automatic Melt Filtration High regranulate quality at low operating costs and that fully-automatic that is the ABMF series automatic belt melt filter manufactured by BritAS GmbH. 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. Filter types AMBF: Typical automatic belt melt filter with buffer store for the melt and a screen surface of up to 1600 cm 2 ABMF-C Continuous: The downstream unit guarantees a continuous melt flow. ABMF-BV Before Venting: Fine filtration before degassing. Melt valve Accumulator Main pipe

2 BritAS uses simulations as basis for product optimizations example optimization grid and die plate Your advantages 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 the filter fineness from 50 μm up to 950 μm. Constant flow through the die plate 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. Flow speed 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. Flow distribution

3 Continuous melt flow through the screen. Reaching the adjustable limit pressure in front of the screen: The fully-automatic screen change is started. 1 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. ~ 120 sec. ~ 18 sec. 6 Via transport rolls, the screen belt is guided until there is clean screen mesh in the filter zone again. 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. 5 The valve will be opened - there is access again for the melt to the filter zone. 4 The wedges will be closed - the screen belt is fixed and sealed again. 3
