Bollegraaf supplies Netherlands' most efficient plastic sorting system
Appingedam, Netherlands-based Bollegraaf Recycling Solutions and Daly Plastics, located in Zutphen, have completed the installation of the most efficient and professional industrial plastic sorting system currently operating in the Netherlands. The two companies pooled their expertise to create an innovative, modular and fully automatic recycling system. The capacity targets set for the system were exceeded by more than 50%. Every hour, the system delivers around 7 tonnes of perfectly separated plastics. This enables Daly Plastics to realize its ultimate goal: production of extremely pure regranulate for use as raw material in high-quality new products.
"We chose Bollegraaf because their quality was higher than all other candidates and they possess the necessary expertise in the design, engineering, construction and supervision services required for the installation of an innovative system like this", explains Peter Daalder, director of Daly Plastics. "Another important reason for selecting Bollegraaf’s systems is their robust yet flexible nature due to the modular structure. Recycling of waste is a process that is continually changing. If the range of materials for recycling changes, then the system can be easily modified and restructured without incurring high costs. In addition, they are a reliable partner who provide all of the knowledge and services required to optimize processes and get the most out of the systems.
With more than 50 years of experience, Bollegraaf says they are one of the most skilled providers of turnkey solutions. "We know that the composition of the waste received for processing is always variable. For this reason, versatility was the key to this system. It inspires us to get the absolute most out of the system. Daly Plastics goal was to process 4 tonnes per hour, yet they are currently achieving between 6 and 7," says Frits Eding, project manager at Bollegraaf Recycling Solutions.
The system
The first part of Daly Plastics new system is a coarse shredder, followed by the removal of any iron contamination. The resulting output is then processed through ballistic separators – Ellipticals by Lubo Systems B.V. (a member of the Bollegraaf Group) – to remove small contaminants such as sand. By means of optical scanning, the waste is then separated into different types and, if desired, different colours. A manual check can then be carried out if necessary. The output then goes through a baler to be processed into homogenous bales. Subsequently, the output is further reprocessed to create the end product via an innovative DRD dry-cleaning system and granulation. Daly Plastics now has all of this technology at its disposal.
Ellipticals by Lubo Systems B.V.
A Lubo Elliptical system is used to separate 2D materials from 3D materials at Daly's new facility. The grilles on the paddles ensure the desired separation size, which can be easily adjusted to any dimensions you wish. According to Bollegraaf, the Lubo Elliptical offers a wide variety of advantages over traditional ballistic screening:
- Extra wide dimensions: up to 2500mm of functional width.
- Air support to optimally aid the screening process.
- Extremely stable motion pattern due to the 6-cylinder combustion engine principle.
- Range of angles via hydraulic cylinder.
- Paddles can be demounted from above.
- Side walls are also demountable, ensuring optimal accessibility for maintenance purposes.
- Low maintenance costs.
- Central lubrication.
- Easy to replace separable bearings without removing the axle.
