Plastic recycling unit BKG®-FIMIC

for PEfor PPfor thermoplastics

Product overview
Integrated BKG®-FIMIC line concepts for recycling post-consumer polyolefins. Available as DO-Line (discontinuous), CO-Line (continuous) and CFO-Line (continuous flexible) for nominal throughputs in the 4–6 t/h class. Systems combine melt filtration, BKG® gear pumps, polymer valves and underwater pelletizing to deliver consistent pellet quality and process stability.

Key features

• End-to-end integration from twin-screw adaptor to underwater pelletizer.
• Design throughput: ~4–6 t/h per line with minimum guaranteed ~4 t/h.
• Filtration capability: typical melt filter fineness 100–150 µm (application dependent) with fast exchange handling.
• Process control: intelligent pump control for pressure consistency across the line.
• Automation: automated venting and process sequences to minimize operator interventions.
• Thermal & mechanical management: mobile components and thermal elongation adaptors to mitigate differential expansion and equipment stress.

Three line concepts — overview
Three concepts address different production and maintenance strategies: DO-Line focuses on maximum capacity per line and fastest filter exchange; CO-Line supports online screen changes with automated venting; CFO-Line combines continuous operation with flexible redundancy and smaller downstream equipment footprint.

DO-Line (Discontinuous Operation)

• High single-line capacity to reduce CAPEX per ton.
• Fastest filter exchange to lower TCO and filter media cost.
• Intelligent pump control for pressure consistency during batch cycles.
• Rheologically optimized configuration to avoid polymer degradation.
• Modular components and pull-screw access for simplified maintenance.
• Adaptors to prevent mechanical tension from unequal thermal expansion.

CO-Line (Continuous Operation)

• Continuous processing with the ability to change screens without stopping the line.
• Fully automated pressure-adjusted venting after screen exchange to maintain product quality.
• Intelligent pump control and rapid filter handling to minimize TCO.
• Rheology-focused design to prevent degradation during continuous operation.
• High automation level to limit operator interventions.

CFO-Line (Continuous Flexible Operation)

• Continuous operation with configurable redundancy and high maintenance flexibility.
• Capability to operate while up to ~50% of downstream equipment is serviced.
• Smaller downstream gear pumps and pelletizers reduce spare part costs and maintenance time.
• Design ensures safe-running performance in case of pelletizer or gear pump failures.
• Pressure consistency and rheological control to secure final pellet quality.

Product resources & media

• Downloadable product brochures, technical data sheets and press releases are available in the product resources section.
• Process and concept demonstration videos for DO/CO/CFO configurations.
