Potassium feldspar is also known as orthoclase, the color is usually red flesh red, yellowish white, in addition to orthoclase there are also perovskite and triclinic crystal system. Usually density in 2.54-2.57g/cm³, abrasive materials and other industrial sectors and the production of potash fertilizer with. Among them in the ceramic industry as embryo ingredients, glaze dosage accounted for 30%, the rest are mostly used in chemical, glass, glass fiber and other industries, with the development of China's social and economic development, the increasing demand, potassium feldspar application prospects are more promising. The main problem of domestic potassium feldspar at this stage, rich in resources, potassium feldspar is mostly symbiotic with quartz, but also with iron-bearing minerals, mica, clay minerals and rutile. In order to improve the industrial value of potassium feldspar, its beneficiation and removal of miscellaneous stones is essential, especially the domestic potassium feldspar contains excessive iron, iron removal is the key to purification.        Next, a brief description of how to remove potassium feldspar and beneficiation equipment process flow. Photoelectric Separation and Removal      Potassium feldspar photoelectric sorting and debris removal, mainly is the original potassium feldspar ore after coarse break or second break associated ore can be sorted and dissociated, the use of photoelectric sorting equipment pre-throw waste tailings, remove the potassium feldspar in the useless quartz, vein or can be separated from the material, so as to achieve the purpose of separation, compared with the traditional hand sorting process, the overall sorting efficiency is greatly improved. Magnetic Separation     Since iron minerals, black mica, tourmaline, etc. in potassium feldspar are weakly magnetic, they can be removed by strong magnetic separation process and equipment to achieve the purpose of separation. Removal of impurities by flotation     When potassium feldspar contains pyrite, mica, or garnet, tourmaline, hornblende and other forms of ferrite containing minerals, the flotation process is mostly used to remove impurities. The process flow of mineral potassium feldspar beneficiation equipment is as follows.    Crushing: Firstly, the raw ore is crushed by jaw crusher, and then sent by belt conveyor to cone crusher for secondary crushing;   Sorting: After the secondary crushing, the potassium feldspar particles are sent to the circular vibrating screen for sieving and transported to the ore color sorter or artificial intelligence ore sorter for sorting, and the waste stone is thrown away after crushing and dissociation;    Ball Mill: After the waste throwing, the concentrates enter the ball mill for ball milling, and the potassium feldspar powder after ball milling is sorted by spiral classifier;     Magnetic separation: The finely ground potassium feldspar powder enters the magnetic separator for magnetic separation, and the selected iron and mica materials are sorted out by strong magnetism according to the material condition.    Flotation: potassium feldspar through flotation, can be very good to enhance the effect, not only to remove iron, titanium, but also to separate out the quartz and other substances. Among them, according to the potassium feldspar companion does not understand, the use of pharmaceuticals will be different, the main agents are acid flotation, neutral flotation, alkaline flotation method. Dewatering and drying: Potassium feldspar concentrate after magnetic separation or flotation or composite sorting. Dehydration treatment by thickener, then into the dryer for rapid dewatering and drying, and finally the dried potassium feldspar powder is the final sorted potassium feldspar concentrate. Among them, the above process flow 4 and 5 because of the different iron content in potassium feldspar and the different forms of iron ore present in it, sometimes magnetic separation or flotation can be used for sorting, but some potassium feldspar iron ore content is high, and sometimes iron ore exists in potassium feldspar in the form of leaching, this kind of belongs to the difficult ore species, at this time will use the joint beneficiation process for sorting, such as magnetic separation - flotation method, reverse flotation - strong magnetic separation method, etc., at this time can be used Joint beneficiation process, such as magnetic separation - flotation method, reverse flotation - strong magnetic separation method, etc.   From the potassium feldspar beneficiation process, the equipment to be used are jaw crusher, cone crusher, ball mill, vibrating feeder, spiral classifier, ore color separator, artificial intelligence sorter, magnetic separator, flotation machine, dryer, vibrating screen, conveyor, etc. According to the existence of different forms of potassium feldspar, there will be some differences in equipment.    The above is the potassium feldspar sorting process, equipment and process flow, Anhui MINGDER is mainly specialized in ore sorting equipment research and development, production, sales in one of the photoelectric sorting high-tech enterprises, the main products are ore color sorting machine, artificial intelligence sorting machine, mineral sand sorting machine, X-ray intelligent sorting machine, not only use potassium feldspar sorting, in all kinds of metal non-metallic ore are used, covering fluorite, talc, silica The scope of coverage includes fluorite, talc, silica, quartzite, phosphate ore, gold ore, high crystalline silicon, coal and coal gangue, etc.      

How to choose ore color sorter? Color sorter as a high-end material sorting equipment, has now been widely used in ore, agricultural food, oil, chemical, pharmaceutical and other industries, the significance of its existence is not only to save time, energy, high efficiency, but also can greatly improve the utilization of resources to achieve greater economic and social benefits.   How to choose the right color sorter?      It is decided by demand-oriented. The main problem in how the equipment output, sorting effect, applicable particle size range, sorting type, equipment stability, service life, price and other multiple factors, ultimately comes down to how the comprehensive cost performance of the equipment.    As a well-known enterprise deeply rooted in Hefei, the capital of color sorter, Mingde Optoelectronics has been deeply engaged in the field of ore sorting since 2014, with independent self-research of color sorter and X-light intelligent ore sorter and artificial intelligence machine with completely independent intellectual property rights. During this period, according to the continuous accumulation of all kinds of ore sorting experience, Mingde photoelectric constantly invested in equipment development and production, always keep technical innovation, and gradually launched a large output, high precision, high stability of super cost-effective models. How to choose a manufacturer with technical advantages for ore sorting?     As a senior ore sorting manufacturer, Mingde Optoelectronics launched AI artificial intelligence sorting machine, which brings ore sorting from 2.0 color sorting era to 3.0 multi-dimensional characteristics sorting era, breaking through the limitations of color sorting sorting.     Color sorting machine to artificial intelligence sorting machine development is 1 to N progress, from color sorting machine sorting can only be sorted by color, to artificial intelligence sorting machine through the ore multi-dimensional characteristics, such as texture, color, shape, color, gloss and other naked eye visible differentiation characteristics of the progress. Artificial intelligence machine can all be extracted, learning, modeling, sorting. Thus, there is a great improvement in sorting personalization, sorting diversification, and sorting efficiency.      A good product needs to be approved by the market. Our Mingde photoelectric artificial intelligence sorting machine after nearly 3 years, in the project, research and development, production, application after layers of gatekeepers, now has been widely used in talc, magnesite, wollastonite, industrial silicon, gold ore, fluorite, lithium ore and other enterprises, to solve all kinds of ore sorting problems.       Ore sorting machine as a high precision machine, used in some remote areas and complex working environment, facing a variety of tests, a perfect after-sales service system is particularly important, famous photoelectric as a well-known old photoelectric sorting manufacturers, we always adhere to the user first, the service concept of the heart escort, and practical action to achieve our commitment, set up more than ten offices in the country, timely We have set up more than ten offices in the country to respond to the needs of customers and ensure the punctuality and timeliness of after-sales service.

Long life of Mineral separator should be maintained routinely   Each machine has its own service life, but we sometimes find that it is actually not so long, is the manufacturer lying? No, the machine is like the human body, people will be sick, need to recuperate, the machine is the same, the machine will be damaged, it needs maintenance. The machine will be damaged, it needs maintenance. Here, the color sorter engineer here to the majority of the name of the photoelectric users to provide color sorter daily maintenance methods, do the following items, your color sorter can maintain a longer life use. 　1, ash scraper dust removed 　Once a week with ash cleaning air gun to clean the dust on the ash scraper leather (hair) brush; once a month to check whether the leather (hair) brush is running smoothly, if there is loose, tighten the loose position. Use a period of time if the skin (hair) brush of the soft skin (hair) tilted to one side, you can take off the skin (hair) brush up and down to adjust it can continue to use. 　2、Sorting room dust removed 　Color sorting machine sorting indoor and outdoor glass such as dust (generally the sorting room before the glass), wipe with a clean soft cloth dipped in alcohol, while checking whether the ash scraper is running normally. When the glass surface is completely dry and clean, then color sorting. 3、Filter drainage All pneumatic supply part of the machine filter device, must do diligent drainage (at least 2 times per shift) to prevent all kinds of impurities into the core components of the machine damage the machine, so as not to cause unnecessary losses. 4、Maintenance operation before each use. Check the color sorter, air compressor, air storage tank, filter and other parts are intact, there is no loose, cleaning the dust and drainage of various parts. 　5、Check in operation Check the signal indication (including work indication, alarm indication) and spray valve action during the operation of the color sorter. 　6、Maintenance operation after work stop 　Please use the air gun to clean up the vibrator (especially the material condensed in the vibrator bucket), the inside of the body, the receiving hopper, and the dust scraping brush.   　Note: When cleaning the receiving hopper with the air gun, it is strictly forbidden to blow the air gun directly into the nozzle opening. Otherwise it will cause damage to the spray valve! Monthly: Check the filter element; check the cleanliness of the dust scraping brush.   　　Precautions for areas with high humidity (1) The humidity in the southern region is high, it is recommended that customers install two moisture filters. (2) the user depending on the site, at least once every two hours to drain, otherwise moisture into the machine will shorten the life of the machine. (3) each filter in the gas circuit (including the internal machine), timely check the drainage situation, and replace the filter element from time to time. (4) careful maintenance to ensure the normal operation of the machine, but also can effectively extend the life of the machine.           Warning: When cleaning or changing the various parts of the machine, please first turn off the power through the on/off button, and then place the air switch on the side of the main unit in the OFF position before cleaning or changing.          Note: Please do not touch the CCD camera lens of the intelligent color CCD color sorter, if the setting and adjustment is not correct, it will affect the color selection effect.

Factors affecting the sorting effect of ore color sorter For the ore color sorter, I believe most mining enterprises have long been familiar with. So, ore color sorter in the process of widely used in the mining industry sorting work, whether it can meet the needs of all customers, its sorting effect by which factors determine or influence it, Mingde photoelectric after a long-term use of our ore color sorter customer analysis, for different materials, different enterprises, we summarized some of the content.       We often say, ore color sorter is a new automatic equipment, some people say ore color sorter is a kind of "robot", usually, ore color sorter mainly by the feeding system, photoelectric system, control system and sorting system four system composition. As a kind of ore sorting automation equipment, and weigh the four systems and judge the value of its work or mainly depends on the ore color sorter color sorting accuracy, processing capacity, raw materials containing impurities, selection of net rate and other factors.   In the actual production process, these factors are one, there are mutual influence and constraints of the relationship, must be examined at the same time. Our company (Mingde photoelectric) developed a new ore color sorter, in the software upgrade and spray valve response speed to meet the case at the same time, the servo system movement speed, the highest speed of the conveyor belt and the purity of raw materials will affect the color separation accuracy and the size of the processing capacity per unit of time; In addition, some manufacturers in the actual sorting process, the bad material cycle sorting, greatly reducing the rate of finished ore, in the effective time The efficiency of the qualified products is reduced within the effective time, which leads to the increase of the take-out ratio. If the take-out ratio is set too high, it will affect the selection rate and processing capacity of these two indicators; if set too low, the selected waste contains too much normal material, will cause waste. In a comprehensive manner, improve the sensitivity, the better the color separation effect, the greater the belt-out ratio; and the output requirements are also a direct impact on the color separation effect and belt-out ratio. Therefore, after analysis, we have increased the track speed of the color sorter. Compared with other manufacturers, our crawler speed is several times of the same industry manufacturers. They want to improve the output, in can not solve the track speed problem, can only increase the material coverage, in the field production, such coverage will seriously reduce the effective distance between the materials, in the sorting will reduce the resolution, resulting in a lot of bad material "escape", therefore, such a way will only make the material to increase the take-out ratio, and further reduce the separation rate. More reduce the net selection rate. In the long run, for our mining manufacturers, simply can not meet the production requirements, let alone recover costs and increase efficiency.       If you can not achieve the expected color separation effect, in addition to improper debugging, there is a little influence is the rate of raw material impurities. Low rate of impurities, impurities between the interval is large, leaving the servo system response time is long, you can also increase the speed of the conveyor belt to improve production. Similarly, the higher the initial purity of the raw material, the less impurities, the higher the accuracy of color selection, the higher the accuracy, the higher the yield. The normal materials and defective materials in the raw materials must exist a certain color difference; the smaller the color difference, the more difficult the color separation, the worse the performance index, the election rate of materials of different colors is also different.     The factor that has the greatest impact on the quality is the problem of color separation accuracy, we know that the high requirements for the finished material is generally to achieve high precision color separation. For example, we take quartz sand as an example, if it is used to make quartz plates, it can not be sloppy, quartz sand for quartz plates must be high purity, quartz sand can not have a little yellow skin on the surface, the hardness of the stone should also be good, so that the quartz plates made to meet the standards of the industry. In addition, high-end quartz used for export, manufacturing wafers, aerospace business, etc. requires even higher quality products. Conversely, quartz used as a filler in general glass, paint, rubber, plastic, etc. is not as demanding. A certain doping rate does not affect the application, so the yield can be pursued appropriately.       Color sorter as a typical optical-electro-mechanical integration system, involving optical-electro-mechanical soft innovation and application in various fields, the speed of upgrading is very fast, is a typical innovative technology products, mining enterprises in the use of caution, to do a full understanding of the color sorter manufacturers, the color sorter operation of in-depth understanding, so that it plays a due investment benefits.

    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.
