What is the working principle of color sorter?

1、Selected materials from the top of the hopper into the machine, through the vibration of the vibrator device, selected materials along the channel transmission, into the sorting chamber of the observation area, and from the sensor and the background plate between the passage.

2、Under the action of light source, according to the intensity of light and color change, the system produces output signal to drive the solenoid valve work to blow out the different color particles to the waste hopper, and the good selected materials continue to fall to the finished product hopper, so as to achieve the purpose of selection.
