Chapter 1 Product Overview
The color sorter is used to sort good materials and bad materials in materials according to color, shape, material
of materials, for example, removing moldy rice in a pile of rice or removing grey stones in a pile of white marble.
The color sorter of Metra Group is currently the leading color sorting equipment in the domestic market. It adopts
the most advanced high-tech product integrating light, machine, electricity, gas and camera in the industry.
It also uses the company’s latest intelligent color touch display, which has a simple and intuitive operation
interface and can be easily identified and automatically adjusted. The dual-view lens structure is designed to
easily identify small chromatic aberrations. Infrared camera with compound use strengthens performance of the
color sorter and improves flexibility and applicability during use. The distributor has low noise, small jitter, large
vibration and more uniform material distribution. The mechatronics design makes the structure of the whole
machine more stable, improves the service life and makes maintenance easier. With advanced self-injection
nozzle and valve drive mode, it features fast response speed, more accurate impact, small take-out ratio, large
output and reduced gas consumption. At present, the color sorting technology is leading in the world, and is
widely used in the sorting of bad materials with color difference in rice, grains, industrial raw materials and other
materials.
This is a high-tech product with strict requirements for installation, operation, use and maintenance. Therefore,
it must be operated by qualified personnel. The operator must be trained according to the training requirements
of the company and must operate in accordance with the instructions of installation, operation and maintenance.

Chapter 3 Working Principles and Product Structure
The working principle: the materials enter the machine from the hopper in the top and are sent to the top of the
slide way through the vibration of the vibrator device. The materials accelerate down along the slide way, enter
the observation area in the sorting box, and pass through the LED light and the background plate. Under the
scanning of the HD lens, the system generates an output signal, drives the solenoid valve to work, and blows
the materials with the color difference into the defect cavity of the receiving hopper through the self-injection
nozzle, and the good materials fall into the good product cavity of the hopper to achieve the sorting effect.
Diagram 1-1 shows working principle of small color sorter and small color sorter includes multi-functional micro
color sorter, single-channel slide color sorter, double-channel color sorter, three-channel slide color sorter.
Diagram 1-2 shows working principle of large color sorter and large color sorter includes four-channel slide
color sorter to ten-channel slide color sorter.
