Quartz sand, also known as silica sand, is a common non-metallic mineral materials, its application field is very wide.
Quartz sand purification is to remove a small amount or trace impurities in quartz sand, obtain refined quartz sand or high purity quartz sand (such as electronic products) of high difficulty separation technology. In recent years, domestic and foreign researches on quartz sand purification process mainly focus on the following aspects:
01. Washing, grading desliming:
As a pretreatment method before ore selection, washing and grading desilting has been applied early and widely, but its removal effect is not very significant for thin film iron and adhesion impurity minerals existing on the surface of quartz sand.
At present, there are two main methods of rubbing and mechanical scrubbing. Because of some quartz ore, the mechanical scrubbing effect is not ideal, therefore, in our country, the rod friction washing technology is widely used and relatively mature.
03. Magnetic separation:
The magnetic separation process can remove hematite, limonite, biotite and other weak magnetic impurities including limonite particles to the greatest extent.
Flotation method is used to remove feldspar, mica and other non-magnetic associated impurities in quartz sand.
Acid leaching is to take advantage of the fact that quartz is insoluble in acid (except HF) and other impurities can be dissolved by acid, so that further purification of quartz can be realized.
06. Microbial leaching:
It is a newly developed technology to remove iron from the surface of quartz sand particles. At present, microbial iron removal is still in the stage of laboratory research.
07. Color selection machine
The last step is also the most critical step to improve the value of quartz sand, when quartz sand after a variety of purification methods, sand containing impurities is still more, quartz sand products on quartz sand purity requirements are higher, what kind of a method can greatly improve the quality of quartz sand?
At present, ore color separator has been widely used in the separation of quartz sand, a good color separator can really choose good sand, mining enterprises can obtain considerable economic benefits, but why some ore owners bought quartz sand color separator can not meet the requirements? That we must do a good job in the early stage of market research before the purchase of color selection machine, first to understand several important systems of color selection machine, color selection machine can be said to be a "robot", color selection machine is mainly composed of feeding system, optical detection system, signal processing system and separation system. Its performance evaluation index mainly includes the following points: processing capacity, color selection accuracy, band out ratio and separation rate. The key is to determine whether color separator color selected indicators of software and hardware, in order to make the color separator with high efficiency and stable color effect, must consider the combination of software and hardware, global which kind of brand color separator can reach high efficiency sand and effectively eliminate impurities of quartz sand, the real can achieve the purpose of further purification of quartz sand?
The development of quartz sand color selection machine of dalian taiyiming photoelectric technology co., ltd. is in the lead. With the coming of 5G era, the intelligent development is particularly prominent. As an independent brand, Timing quartz sand color selection machine has already stepped into the high-end color selection, and it can be said that it is the leader in the industry. Due to its sand selection effect ideal, high cleaning rate, high output, time-saving energy saving, equipment quality and other characteristics, quartz sand market share in China up to 80%, such a large market share can fully demonstrate the reliability of its products.
Tai - Ming quartz sand color selection machine to the quality of the road. Software is the soul part of the color selection machine, tai-ming color selection machine software part are imported from South Korea, can be efficient and accurate to complete the task, efficient and stable system is really overpowering, but it also needs strong hardware support, in order to further play out the advantages of its high-end brand. The hardware part adopts international famous brands:
1. Professional Japanese NIKON lens, which can identify tiny impurities of 0.1mm;
2. German FESTO high frequency valve with the highest action frequency up to 1000Hz/ second;
3. In order to ensure the air intake quality of the high-frequency solenoid valve, German FESTO filter is adopted;
4. Taiwan mingwei power supply;
5. Schneider control unit of France.
Taiyiming quartz sand color selector high matching of hardware and software can be described as a comprehensive explanation of high-end color selector. The perfect combination of software and hardware proves the dominant position of Timing superstar quartz sand color selector. 5G era, we will see a more outstanding tai-ming color selection of the peak lead, the future can be expected!
