This paper describes the reasons why the quartz sand selection machine can not achieve the desired color selection effect
With the rapid and efficient dissemination of market price information, mining products are generally similar and standardized and trade in a transparent manner. Most common way is through cultivating brand loyalty of manufacturing, market segmentation, or other means to improve competitiveness, according to the current situation seems, however, guarantee the high price and profit growth is the most fundamental, or to guarantee the quality of ore. Today, with the rapid development of technology and technology, the quality of the ore is increasingly strict today. What kind of sorting equipment can meet this requirement? No doubt, the ore color selection machine, the quartz sand selection machine.
The most commonly used quartz sand, for example, if it is used for quartz plate, it can not be careless, quartz plate with quartz sand must be have a pure white and it is acid, on the surface of quartz sand can't have a little bit of yellow skin, the hardness of stone is better, is like white kind of quartz sand, in this way can make quartz plate meet the standards of the industry.
If quartz sand is used as filler in coatings, rubber, plastics and other fields, the demand is not so high, and there is a certain doping rate and it can be applied to the production. Too much sensitivity can cause the solenoid valve to blow too much into the protective state, which may result in poor color selection.
In addition to the improper index setting, there is also a small influence factor which is the heteroefficiency of raw materials. When impurities are rare, the two impurities are spaced apart, leaving a long reaction time for the servo system, which can increase the speed of the conveyor belt and increase the yield. Similarly, the higher the initial purity of raw materials, the less miscellaneous quality, the higher the color choice accuracy.
The normal materials and defective materials in raw materials must have a certain color difference. The smaller the color difference, the more difficult the choice of color, the worse the performance index, and the different selection rate of materials for different colors.
