Quartz sand having unique physical and chemical properties, for the manufacture of glass, refractory materials, silicon iron smelting, metallurgical flux, ceramics, abrasive materials. In the construction industry, quartz is used to produce acid-resistant concrete and acid-resistant mortar with strong acid and medium resistance. Quartz sand as a core material for silicon raw materials plays an important role in the production of silicon raw materials. At present, the purification of quartz sand mainly passes the magnetic separation method and the flotation method, but there are still many impurities after magnetic separation and flotation. In addition to manual sorting, these impurities have a better method to eliminate - color selection. The meaning of color selection technology Photoelectric color selection technology refers to the use of special identification lens to capture material surface image signal, collect material transmittance signal or use infrared, ultraviolet and other methods to determine the moisture and other components of the material, and use processor processing to achieve photoelectric signal conversion, And compared with the standard signal to analyze the quality of the material, and then use the actuator to remove the inferior material, is a high-tech integrated technology integrating light, electricity, gas and machine. The cost of manual sorting is getting higher and higher, and the difference between high-purity quartz sand and low-purity quartz sand is very large. The application of photoelectric color sorter is extremely advantageous from the economic point of view or from the ecological point of view. Effective, so the study of quartz sand color selection technology has profound significance. Quartz sand color sorter working principle The quartz sand color sorter is a high-tech optoelectronic integrated mechanical device that automatically sorts the heterochromatic particles in the granular material by using optical equipment according to the difference in material color. The selected material enters the machine from the hopper and vibrates through the vibrator device. The selected material enters the observation area of ​​the sorting chamber along the passage, passes between the CCD sensor and the background plate, and the CCD receives the selected material from the selected material under the illumination of the light source. The synthesized optical signal causes the system to generate an output signal, and is amplified and transmitted to the arithmetic processing system to convert the optical signal into an electrical signal, and the control system issues a command to drive the electromagnetic valve to spray and blow out the heterochromatic particles to the waste area, and the continuation continues. Down to the good area, to achieve the purpose of sorting. Analysis of market prospects of quartz sand color sorting machine China is an important raw material producer of quartz sand. In recent years, the global demand for industrial quartz sand will increase every year, and this trend will not change in the short term. At present, the quartz stone product market is similar to the artificial stone market 10 years ago. In the future, the market will increase at a rate of 500% per year, with huge market space. Among China's quartz sand consumption structure, metallurgical industry and refractory materials are the main consumers in the current quartz stone market, accounting for about 62%, and the total amount of other industrial fields accounts for 38% of the total market. At present, the total annual consumption of quartz sand in the country is about 3.4-350 million tons, of which medium and low-grade quartz sand and medium-to-high-grade quartz sand each account for about 50%. In 2011, the total output of quartz mines nationwide was 332 million tons (including medium, low and high-grade products), with a sales income of 725 million yuan. According to relevant information, the current annual consumption of medium and high-grade quartz sand is 2.8-290 million tons, and China consumes 1.15-1.20 billion tons of medium and high-grade quartz sand, accounting for 41% of global consumption. Quartz sand has a broad market. Therefore, it is particularly important to improve the quality of quartz sand products, improve production efficiency and reduce costs. At present, the cost of manual sorting is getting higher and higher, high-purity quartz sand and low-purity quartz. The difference in sand value is very large. The application of photoelectric color sorter is extremely beneficial and effective from the economic point of view or from the ecological point of view. Therefore, the use of large quartz sand color selection equipment is essential for the development of quartz sand enterprises.
