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.
