The Conical twin screw extruder TT-ACT system is a specialized and dependable solution designed for high-capacity recycling and re-pelletizing of rigid plastic scraps.
It’s an efficient and uninterrupted system capable of transforming rigid plastics like PP, PE, ABS, PS, PVB, and PA flakes, regrinds, and crushed plastics back into granules. This process involves melting, plasticization, vacuum degassing, and a filtration system.
In order to achieve automatic feeding of plastic flakes, both a screw loader and screw feeder are integrated into the single-screw extruder system. By standard design, plastic flakes are conveyed into the screw feeder via the screw loader. Additionally, an optional magnetic frame can be installed in the screw loader storage silo to detect any material containing metal. The feeder motor is regulated by an ABB or Schneider inverter, while a level sensor installed in the hopper of the screw feeder enables automatic feeding.
A specialized conical twin-screw extruder designed specifically to gently melt crushed plastic scraps, featuring a capacity range of 400-2000kg/h. The extrusion unit comprises a high-torque gearbox, motor, screw & barrel, and a vacuum degassing system. The screw & barrel are crafted from bi-metal material, ensuring significantly prolonged lifespan. Standard ceramic heaters are installed on the barrel to facilitate heating and melting of plastic scraps, complemented by air blowers for barrel cooling. There’s an option for infrared heaters, which are easily assembled and disassembled, offering faster heating and energy efficiency. They promote more effective heat conduction, resulting in longer service life, maintenance-free operation, lower energy consumption, and increased output capacity.
– You have the option to install a standard single-plate/piston double-station screen changer or a non-stop double plate/piston four-station at the extruder head for considerable filtration performance. – Extended screen lifespan and reduced frequency of screen changes: The filters feature a long lifespan due to their large filter areas. – User-friendly and continuous operation: Quick and easy screen changes without interrupting the machine’s operation. – Minimal operational expenses.
The Plate type filter is designed in a continuous format with two filter plates, ensuring that at least one filter remains operational during screen changes. A ring-shaped heater is used to maintain consistent and stable heating throughout the process.
This model incorporates our in-house developed self-cleaning filter. The innovative SCF (Self-Cleaning Filtration) system enables continuous recycling extrusion, particularly ideal for re-pelletizing highly contaminated materials. The SCF filtration system efficiently manages and eliminates up to 5% of contaminants in the flowing melt, capable of segregating contaminants such as paper, wood, aluminum, unmelted plastic, and rubbers, among others.
– Self-adjusting pelletizing head ensures optimal granulate quality and prolonged uptime by maintaining consistently correct blade pressure.
– RPM of the rotatory blades is automatically adjusted based on the melt extruding pressure.
– Quick and effortless pelletizer blade changeover, eliminating the need for adjustment work, thereby saving time.
A highly automated pelletizing system tailored for materials with high Melt Flow Index (MFI) and demanding production capacities. This comprehensive system comprises a pelletizer, valve, conveying pipeline, dewatering vibrating screen, and silo.
– Advanced dewatering vibration sieve, coupled with horizontal-type centrifugal dewatering, delivers highly efficient drying of pellets while reducing energy consumption. – Assembled using screws instead of welding, the sieves can be easily replaced or changed in the future for convenience.
The end result is plastic particles, allowing the plastic pellets to be reused in the production of high-quality plastic products once more.
– This is where the final qualified granules are stored. The drying shaker, combined with the horizontal centrifuge, ensures effective drying and reduced energy consumption.
– Continuous capacity monitoring & Quantitative weighing system are implemented for precise measurement.
