Technologically advanced CXR 3F separation system

Our new CXR 3F sorting unit can separate material for the three different fractions in the only one sorting unit. It bases on the XRT analysis technology combined with two separates nozzles.

The result of our work on the separation systems is create new type of sorting unit who can select two different materials from the input material. After Implementation, this solution we can reduce quantity of the separation unit in factories.

Chosing CXR 3F Separation System, you are choosing Advanced Rejection Control. Our solution is characterized by a separate system based on an FPGA processor.

CXR 3F separation system

We have equipped the CXR separation system with an intelligent decision-making system. Thanks to this, some procedures are carried out much faster than. This acceleration is seen on three levels:

The principle of “unconditioned reflex” for complex image analysis
Accurate analysis using basic characteristics (color, size)
Comprehensive analysis using all available information

How does the CXR 3F separation system work?

In the vibratory feeder, individual rocks are dispersed before they even fall onto the horizontal conveyor belt. Then, the material goes through the X-ray analysis. In this part of the separation process, various particle properties are analyzed and recorded.

The CRX is operated by a control system based on an industrial computer. It uses a special algorithm that works according to carefully selected separation criteria. More than 50 parameters can be used to identify a particle.

The CRX system also allows you to combine individual parameters into additional combinations. Thanks to this, you can more effectively distinguish the particles of interest to you. Since each particle to be separated has a specific shape and position on the belt, it is possible to precisely use the rejection mechanism (compressed air nozzles) to separate them from the material flow. We can select 2 different materials with totally different parameters by using the two different rejection nozzles. It give us two different separation fractions and one not separation fraction.


We designed the CXR 3F separation system to meet even the most demanding requirements. Our many years of experience in the field of creating sorting, pulverizing and separation systems has allowed us to create a solution that will work in industrial processes, especially in the mining industry.

You can use CXR 3F to sort, among others:

Nonferrous metals
Metal ores
Mineral ores

It is also perfect for the recycling industry.


We present a detailed table in which we have compiled a comparison of the most important technical parameters of the CXR-3F-1000. They differ in maximum capacity, the number of reject valves and the amount of compressed air used for material separation.
