Recycling of Non-Ferrous Metals

Metal articles have been subject to secondary use practically since the invention of their processing technology. Modern technology grapples with the issues of maximum recovery of fractions of many non-ferrous metals and their alloys that are impossible to separate based on density and other physical properties.

SmartSort optical sorting technologies, distinguishing the smallest differences in shades, allow obtaining very high purity levels from scrap regrind, facilitating the further metallurgical process, already at the sorting stage.

The value of effective metal separation

  • Recycling of non-ferrous metals requires processing large amounts of raw material, which includes various non-ferrous metals and contaminants. The separation process is difficult. The problem is not only cleaning non-ferrous metals from contaminants found in the mass of the processed raw material but also sorting metals into their individual types. This process is usually carried out in multiple stages, which significantly increases production time and cost. Smartsort perfectly implements the multi-stage process of dividing raw materials from recycling, which cannot be divided using other technologies.
  • Companies specializing in the professional recycling of non-ferrous metals are placing increasing emphasis on the quality of the raw materials they offer. Only a pure product can offer a high price. Companies using recycled raw materials adopt a similar approach. Pure raw materials are treated as finished semi-finished products that can be immediately incorporated into the production process, while impregnated products can be either unusable or unsellable.

How to use an optical sorter in a company?

  • The importance of the quality of the sorting process and the way such work is organized is constantly growing. Smartsort devices are an excellent solution for companies dealing with recycling, but also for manufacturers purchasing raw material from recycling. Our advanced optical technology combined with refined, durable, and effective sorters means that what once had to be done by a human can be fully automated.
  • Smartsort sorting lines for non-ferrous metals take up surprisingly little space and are relatively easy to integrate into the production cycle, precisely where they will be most effective. Their high flexibility allows for easy selection of a machine appropriate for the processing volume and material. The company offers several series of optical machines that perform excellently as metal and contaminant separators. The device can be customized to meet the expected performance parameters. You can also choose a sorter appropriate for the grain size and weight of the typical raw material circulating in the plant.

High purity of recovered metals already at the sorting stage

The unprecedented quality of sorting of non-ferrous metal regrinds is achieved thanks to the operation of Cloud color cameras of unprecedented resolution and signal processing by EagleEye software, which in its current version is based on machine learning models and, at the execution stage, uses a proprietary system of integrated circuits controlling the pneumatics that reject unwanted elements.

Thanks to LED strips of our own production used to illuminate the sorted assortment and variable background colors supporting contrast, even better sorting effects are obtained.

If necessary, machine learning algorithms used in the EagleEye software, which directs the work of SmartSort sorters, allow detecting defects not only based on colors but also the shape and size of elements.

InGaAs camera technology based on our own patent for sensors supports the separation of very dark metal and non-metal fractions found in non-ferrous scrap regrinds such as rubber or plastics.

Optical sorting on an industrial scale and beyond

SmartSort optical sorters are available in systems from 1 to 12 channels in one device, making them suitable for use in both small sorting plants and large industrial plants.

For assortments with exceptionally heavy and large grains, SmartSort has a number of solutions based on a belt structure, stabilizing elements with high inertia.

Separation of any fractions

The ability to configure individual sorting channels separately enables multi-stage sorting and re-sorting options adapted to the actual mixing levels of individual assortments. Electromagnetic pneumatic valves used in SmartSort sorters were designed by the manufacturer specifically for extremely fast, precise shots of compressed air. Thanks to this, losses of the desired material are minimized, especially with finely ground regrind.
