6 Things To Consider To Choose The Right X-Ray Sorting Service

X-ray sorting process makes use of advanced technology that applies dry-mechanic techniques for separating materials and waste stream. It separates it based on specific atomic density and uses high-resolution X-ray transmission image processing to carry it out. Hence, it can efficiently recover valuable materials.

Irrespective of size, moisture, or surface pollution level, X-ray sorting machines make it possible to get a high purity level while sorting materials. It can be used to sort mineral resources, metal ores, gemstones, coal, and other materials. In X-ray sorting, two leading technologies are used commonly. The XRF technology allows the waste materials to pass beneath X-ray sorting scanners. On the incoming waste products, the X-rays are beamed out. It absorbs the X-rays, which are then read by the X-ray sorting machine. Each material has varied absorption levels. Usually, the thick or dense waste materials show a higher absorption rate.

The other one is the XRT technology. In X-ray transmission sorting, it identifies contents in the sorting material without considering the color or pollution. It separates material based on its specific atomic density into different material types. The electronic x-ray sorting projects designing and assembling helps to speed up the sorting process. To choose the exemplary electronic Xray Sorting service for your business, consider the following points. 

Business Needs

Based on density differentials, X-ray sorting can identify metal, stones, hard bones, glass plastics, and other materials. It would help determine what the X-ray sorting service solution will help you achieve in your business. The sorting service solution can help you in the process of mineral sorting and to many other fields. Hence, to choose the appropriate solution, you need to determine the end-use.


Before choosing a service solution for your business, you need to identify if the supplier has credible experience and expertise in this field. You can research the customer base to know about the pros and cons of working with the concerned vendor.

Type Of Technology Used.

Determine the type of technology they use in their service. The X-ray sorting machine should work independently of particle size, particle shape, chunk weight, surface color, and impurities. It should efficiently sort out unwanted materials, and the chute system should have a simple build for easy maintenance.

Optimize Time

Downtime can lead to a decrease in revenue. System uptime can make a dramatic difference in the material sorting process. It can add efficiency and profitability to your entire operation. It can add value to your business; you can mine sub-economic waste previously at lower costs. Moreover, it can increase productivity and reduce cut-off grades, and increase reserves. There is also a positive impact as it also minimizes environmental impacts.


Determine the cost of the X-ray sorting service. The equipment allows you to create ore concentrates at a meager cost in small or remote mining installations. You can plan the process in semi-mobile form and only include crushers, screens, belts, and sorting machines. It helps to immensely save the cost for transport, as the waste materials are disposed of on-site. 

The x-ray sorting service should complement and minimize the burden on downstream stages of conventional processing. With this, you can bring down the overall costs for process materials like water and leaching agent. 

Sorting Principle

You need to evaluate the sorting principle deployed by the service. Generally, the input material is fed through a screen feeder or vibration feeder via a transition chute onto a conveyor belt. An electric X-ray tube is used for the creation of broad-band radiation. The radiation enters the material and gives spectral absorption information, measured with an X-ray camera using appropriate sensor technology. 

The processed sensor information provides a detailed “density image” of the material. It allows it to separate the material into high and low-density fractions. Suppose the sensor finds out material that needs to be sorted out. In that case, it passes information to the control unit to open the appropriate valves of the ejection module, which is attached to the conveyor belt. The detected material is separated from the material flow via jets of compressed air. In the separation chamber, the sorted material is then divided into two fractions.

Use Of Intelligent Systems

An intelligent system augments the decision-making process. It helps to execute the strategy faster to get optimal operating time on three levels.

  • ”Unconditioned response” principle: The “obvious” particles are identified without involving advanced computation procedures
  • Accurate analysis: It is performed using the primary feature (such as color, size, X-ray attenuation), and hence it is more time consuming
  • Complex analysis: It uses the available information and is very time taking

You can choose digital filtration, carried out through geometrical parameters, morphology analysis, FFT filtration, shape matching, color matching, color pattern matching, X-ray response pattern matching.

To Conclude:

You need to determine the nature of the sorting operation to choose the exemplary service. An effective X-ray sorting machine will help you to sort out unwanted materials without much hassle efficiently.
