The Development Of Iron Ore Preparing Technique

Published by at 12:49 pm under News

The iron ore is one of the most important raw materials for steel production enterprise. Through crushing, grinding, magnetic separation, flotation separation and re-election by crusher, such as jaw crusher, cone crusher and so on, the can be selected from the natural iron ore (iron ore). Iron ore resources in China have two characteristics, one is more lean ore. The reserves of lean ore take up 80% of the total reserves; the other is more symbiotic multi-element composite ore. In addition the ore body is complex. Some poor iron bed has hematite en upper part and you have magnetite at lower part. Thus, the process of iron selection is troublesome.

In allusion to the existing characteristics of iron ore in China and the higher iron essence requirements of iron industry, the technique of preparing needs to be improved and the preparation equipment also needs to be improved as soon as possible. The beneficiation process should be efficient and simple as much as possible. For example, we need to grasp the development of energy saving equipments to use the most suitable process to achieve the best effect.In the concentrator, the equipment investment, production cost and the steel consumption of the crusher and grinding operation often takes up the largest proportion so that the selection of the crusher and grinding equipment and operation management determines the economic benefits of the concentrator in a large extent.With the international crushing technology advanced, the hydraulic cone crusher produced by Henan Hongxing Mining Machinery Co., Ltd. is a kind of cone crusher with international advanced level. The perfect combination of high performance crushing cavity and high crushing frequency greatly improves the processing capacity of this equipment. And owning to the adopting laminated crushing principle, most of the crushed materials are in cubic shape, reducing the needle type materials in a large extent. The optimum design and hydraulic protection makes this equipment have fewer breakdowns. Generally speaking, its fault-free operation can surpass 85% ratio.
