The development of the theory of color separator from agriculture to industry difficult course Introduction to the Color separator is based on the differences of the optical properties of material, using photoelectric detection technology of granular product, the different color particles automatic sorting equipment.Color separator is used for medium material quality inspection and grading a nondestructive separation equipment, in food, food, pigment, chemical and other industries has been widely used. The principle of Was selected from the top of the hopper into the machine, through the vibration of the vibrator unit, selected material falling along the channel, accelerate whereabouts into separation indoor observation area, and through the between the sensor and the background plate.Under the action of light source, according to the strength of the light and color change, make the system to produce the output signal to drive the solenoid valve work out different color particles blow to meet hopper waste cavity, and good selected finished materials continue to fall to meet hopper cavity, so as to choose other purposes. Name DE photoelectric with first-class technology, years of experience in research and development of color separator, the selection of the color technology combined with practical application, the ore separator of color, can choose a variety of industrial minerals, the effect is good.Industrial ore fields widely used and high value.After separation of the ore, purity and quality in an instant, double value quickly. The problem As a result of the need of industrial development and the necessity, especially the requirements of the metals and ore class more and more strict, the application of color selection technology is especially important.Ore type of industry, for example, currently on the market to meet the requirements of ore production color to choose the color of separator enterprise, the few high accuracy is very few.Parts factory research and development can't keep up with, backward technology, with food color separator instead of industrial color cell behavior is of others, shoddy.Not only work efficiency is low, the damage to the machine rate is also increasing rapidly. Successful cases DE photoelectric color caterpillar ore separator, just cater to the needs of customers for mineral separation, using 24 full-color high-speed industrial camera acquisition, for different color material found in ore, can achieve high resolution, according to the customer request, don't want all the bad material selected.Computer control, a more simple and quick.The whole process of color choose, only into the material, the computer debugging, and then you can see the effect of color to choose.High precision, saves the manpower at the same time also can improve the work efficiency. conclusion Nowadays, food color separator nearly saturated, most of domestic manufacturers are in research and development more possibilities, such as the key research and development production ore color DE photoelectric in the name of the machine is still working on research and development to develop new products, let the color separator into more areas, open up a bigger market.Let color choose technology shows the possibility of more, this is the color separator field most should do!
