Optical sorting machines

Optical sorting machines

Optical sorting machines for bulk materials, designed for the separation of regrinds and food products, are an ideal solution wherever quality and purity of materials are prioritised.

Ekochem’s sorting machines deliver cleaning efficiency of up to 99.99%. Their capacity ranges from 500 kg/h to 16 t/h, depending on the input material and contamination level.

Our sorters are equipped with advanced data processing technology, allowing for quick and precise sorting.
Cutting-edge CCD cameras guarantee the best component recognition possible. Highly durable pneumatic solenoid ejectors are characterised by long-term, failure-free operation without loss of calibration.

Frequently
Asked Questions

How does a sorter work?

Sorters automatically identify and segregate materials. Depending on their type, sorters use optical sensors or colour sensors (NIR – Near InfraRed), pneumatic ejectors, or mechanical systems to separate processed material from contaminants or foreign objects.

What are typical outputs [t/h] and how are they affected by contaminants

Typical outputs vary between 0.5 and 6 t/h, depending on a model and type of material. Contamination (paper, sand, metals, moisture) lowers the efficiency as it requires more frequent rejects and additional separation stages.

What in-line separators do you offer? Are these magnetic or gravity separators?

Our lines use magnetic separators (for separating ferrous metals), as well as electromagnetic and gravity separators (for separating heavier contaminants such as sand and glass). The choice depends on the material type and contamination level

What is re-sort like?

Our sorters feature a re-sort system, where rejected material goes through an additional section or returns to a conveyor belt. This way, valuable plastics are recovered from the rejected material, and the purity level of the end product can reach even 99%.

Can separation be adjusted to various types of waste (plastic, paper, metals)?

Yes, our separation systems are fully adjustable to different types of waste. We apply optical separators (based on plastic colour and polymer material), air (paper, light foil), magnetic, and metal detectors (ferrous and non-ferrous elements). They ensure flexible operation with a mixed material stream.

What is the accessibility of your authorised maintenance services and domestic application support?

We provide maintenance services in Poland as well as local application support. Our engineers usually respond within 24-48 hours. We also offer technological consulting during commissioning, calibration and line optimisation.

What sensors do you use, and what is their accuracy/reject rate?

We use optical sensors (colour-detecting camera, NIR – Near InfraRed), metal detectors, and high-resolution visual sensors. Their accuracy usually falls between 95-98%, while the reject rate is around a few per cent, depending on the type of waste and process settings.

What is the lead time from placing an order?

Precise production and delivery dates are determined individually after the machine specifications have been approved. Please contact our technical and sales departments to estimate the lead time.
