Metal processing
State-of-the-art sorting is the goal of many recycling companies today. The topic of NIR is becoming increasingly important. The aim is to further improve the sorting of different materials with the help of near-infrared spectroscopy.

Benefit from the Screening process & Feeding
Our team would be happy to advise you on NIR sorting and how SPALECK technology can help you get the most out of your NIR system.
BEST SCREENING. BEST INFEED. FOR BEST SORTING QUALITY.
Sensor sorting with near-infrared technology is suitable for a wide range of recycling materials. NIR sorting systems are widely used today. This is because they help to increase the accuracy and efficiency of recycling. Common areas of application are almost all types of recycling materials.
These include, among others:
We would be happy to advise you on how you can optimize the recycling rate of your materials with the help of NIR sorting and our SPALECK Screening technology.
To that end, we offer to test your materials at our TestCenter. Of course, you can further process the materials prepared in this way at the testing centers of NIR sorting plant manufacturers. This is part of our daily routine, and we’d be happy to assist you with this.
Do you have a project idea?
Simply send us a photo of your material and relevant key points about the project and we will get back to you as soon as possible.

More Information
NIR sorting plants are fully automated sorting plants that sort a wide variety of materials according to their near-infrared spectrum. They belong to the group of sensor-based sorting systems. In recycling, it is a modern and established technology for reliably sorting materials according to their molecular composition. The interaction of the recycling technology used is crucial here. For example, screening machines, Infeed hoppers and Vibratory feeders carry out elementary preparatory work so that NIR sorting can be carried out economically.
In NIR sorting, the recycling material is fed to the NIR sorting plant via a conveyor belt. A light source installed above the conveyor belt irradiates the various recyclable materials with infrared light. This physical analysis technique uses infrared rays in the 760 – 2500 nm range. Depending on the material, more or less of the wavelengths are reflected. The NIR sorting device assigns the individual piece of material to a specific material class based precisely on this information about which wavelengths are absorbed or reflected.

More InformationThe aim and necessity of recycling is to process large volume flows in the best possible way. This is necessary so that recycling can be carried out economically. Thanks to the technical design and the screening machines and Vibratory feeders specially designed for your recycling process, your NIR sorting devices are fed very consistently. This enables very high throughputs. At the same time, it allows the materials to be separated so that the NIR technology can optimally detect them. You thus obtain a monolayer in the feed width matched to the NIR device. This enables perfect feeding and very good separation results.
