Deltoid develops cost-efficient, energy saving and environmentally friendly turnkey solutions for pneumatic waste management – Made in Germany.
This guarantees the minimisation of interface problems, as well as a smooth total process.
Cost-efficiency though maximum flexibility and reliability
Today in the paper industry, a wide variety of cardboard packing and paper grades must be produced with maximum flexibility and with minimal setup times.
Ever increasing environmental and quality requirements in the recycling process require unmixed waste sorting even in production facilities. This development shows that sorted production waste recycling is a perfect example for resource efficiency and economic value.
In the last years, the average machine speed for paper and winding machines has increased significantly. Similarly, the amount of and trimmings increased in this same time /period. An overview of the total waste at all paper and winding machines plays a decisive role here.
The scope of performance of the Deltoid extraction systems
currently ranges from 14 g/m2 to 690 g/m2
Example
| Paper- / winding machine | Old |
| Machine speed | 1800 m/min |
| Paper/ cardboard weight | 180 g/m2 |
| Edge strip width | 2 x 50 mm, max. |
| Edge strip waste | 1.944 kg/h |
| Paper- / winding machine | Modernised |
| Machine speed | 2500 m/min |
| Paper/ cardboard weight | 180 g/m2 |
| Edge strip width | 2 x 50 mm, max. |
| Edge strip waste | 2.700 kg/h |
| Extra waste | 756 kg/h |
These extra quantities of waste must not only be pneumatically gathered and transported, but also further processed, e.g. in the baling press, the pulper or the filter system.
To minimise the risk of possible facility downtime, parts of the edge strip waste system must be modernised or re-designed.
Looking at the whole extraction system is of great importance here. The demand for maximum availability, production flexibility and economic efficiency places the highest demands on the optimal dimensioning and design of the total system, right from the suction nozzle to the filter system with a heat recovery system.
A task that Deltoid has successfully been devoting itself to for decades.
Deltoid extraction systems offer multiple advantages here – modular, safe, flexible.
The modular and redundant designed Deltoid complete systems can be integrated into a machine data logging system (e.g. Hydra-Manufacturing-Execution-System (MES)). This way, the performance of the extraction system. This way, the performance of the extraction system is automatically set up for the respective production process with the use of state-of-the-art technology.
In case of a paper grade change, the diverter valves at the end of the feed pipe automatically switches to the required waste fraction.
This not only saves/ reduces setup times, but also ensures unmixed production waste sorting while simultaneously reducing energy costs.
The producer therefore achieves high prices for his sorted paper waste, while ensuring a significant increase in the quality in the further recycling process.
The simple and cost-effective method of separating cardboard and paper grades stands for higher energy efficiency, cost-efficiency and short amortization times for modernisations or new investments. The ROI (Return On Invest) is thus achieved much sooner.
Lowering operating costs through intelligent heat recovery
Generally, the transported air from the pneumatic extraction system is not further used. The released transport energy / process warmth from waste transportation is usually directed out into the air, unused.
In order to ensure a balanced air quality in the production rooms, it can be important for the extracted air amount to be re-directed into the system. This can, for example, take place using a cross-flow heat exchanger, enabling up to 80% of the energy in the outgoing air to be regained.
The yearly operating costs / investment costs for external ventilation systems can be thus significantly reduced.
Clean cut, quality made visible
For completely wound coils the quality of the cut is directly connected to the cutting and extraction process.
A methodical mechanical and electrical adjustment of the extraction system to the cutter in the early project phase is the prerequisite for maintaining the highest production quality of the completely wound coil. Thus the early project planning decisively influences the production quality of the completely wound coils.
At the same time, the facility operator receives the maximum flexibility for the production of a wide variety of tape and foil types at differing winding speeds. The perfectly designed extraction system rules out the need for after-treatment of the coil.
