Three kinds of spiral mining equipments for you

Spiral classifier is one of the beneficiation equipments. According to the different proportion of solid particles, the rate of precipitation in the liquid is also different. Spiral classifier concentrates fine ore based on the principle. After grinding, the materials will pass through filter, through which the coarse materials will return to ball mill and the fine ore will be discharged from the overflow pipe. The necessity of spiral classifier in the industrial production is obvious. Rare gold, silver and other metals separation often use classifier. China classifier technology has a rapid improvement since 1950s. While the advanced grade technology is applied, we also blended into our own technology. At present, the China classifier has reached advanced international level. We produceclassifiers, which are completely able to do long-term industrial operations, and the quality is absolutely reliable. The advantages of the spiral classifier are:

stable and reliable performance, easy-to-operate, can be connected with the ball mill without pump. The biggest spiral classifier specification made in China is φ3.0 m, can reach artesian connection with φ3.6m x4.0 m ball mill. The big volume of the spiral classifier has buffer action and plays the role of transporting material, while the return concentration can be as high as 65% to 80%, thus good for the grinding operation.mine resources are mainly divided into two categories: one for the vein gold mine, deposits mostly in the mountains, formed by the internal geological forces (mainly volcanism, magmatic, metamorphism), also known as rock gold mine or Endogenous gold; and the other for alluvial gold.Gold resources are very rare and gold dressing is not easy. Now we has discovered 98 kinds of gold ore and gold-bearing minerals , of which only 47 species are common, and there are only 10 kinds of minerals which can be directly used in the industries.

The mainstream gold ore dressing technology is generally through the ore dressing equipment (crusher) to broken gold ore, and then sent into the gold beneficiation (ball mill) to be smashed and grinded. After the gravity separation and flotation, concentrate ore and tailings are extracted, and then by using chemical methods and final smelting, the finished product eventually become gold.As the leading mining equipment manufacturer, KEFID can provide you with the gold ore crushing equipment and grinding machine including vibrating screening equipment. Apart from jaw crusher, stand cone crusher, short head cone crusher and ball mill, KEFID can also provide you with impact crusher, VSI crusher, mobile crusher, coal mill, Raymond mill, high pressure grinding equipment and coarse powder grinding mill.
