What factors and indicators determine the selection effect of quartz sand selection



The ore color selection machine, many people may feel very strange. It is a large sorting machine for the ore industry. Based on the principle of photoelectric, the application of ore color selection, the application of ore color selection, improved the quality of the products, improved the production efficiency, and improved the value of raw materials. For example, the application of ore color selecting machine to quartz sand has a far-reaching influence.

Ore color machine has been widely used in the separation of quartz sand, many mining companies see their peers using color separator made economic benefit, find themselves also need a color machine, can be in the actual production after buy but could not reach the requirements of want, why? In the actual production process, these indicators are integrated, there are mutual influences and constraints, and must be examined simultaneously.

The factors influencing the color selection precision and unit time throughput are mainly the speed of the servo system, the maximum speed of the conveyor belt and the purity of the raw materials. The ratio of the ratio is adjustable, and if it is too high, it will affect the selection rate and the processing quantity. If it is set too low, too much of the normal material in the selected waste can be wasted.

For different application fields, debugging different performance indicators, the less sensitivity the better the color selection effect can satisfy the requirement. 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.

Should also pay attention to the different application requirement for raw material is different, so must not only pursue the production, 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 the 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.
