Iron ore is of strategic mineral resources, the relationship between the development of China's important industrial areas. Focus on the object and beneficiation of iron ore beneficiation process equipment are mining industry, here we introduce you to focus on finely ground ore crushing process.

Iron ore beneficiation process is completed after mining and processing, the most important part of the process is crushing and grinding stages. Finely crushing process is among the most critical processes, but also the highest consumption of energy a program. Therefore, strengthening the broken features, stone quarries and other mining and ore mined is about crushing to a particle size is reduced to a minimum and is technically feasible to meet the size of the next work program requirements, improve work efficiency, reduce the cost of most reasonable program.

Under normal circumstances, the ratio of the degree of crushing operations should be between 6 to 7-100 to 130, the current device as well as a combination of domestic mining beneficiation process for small and medium crushing plant using a two-stage or some were broken open: Large broken workshop, the use of three or four paragraphs break: For fine disseminated ore, through the use of technology in order to make useful finely ground minerals reached a relatively sufficient monomer dissociation, and then be able to make use of appropriate technology sorting, which is essential for high-quality ore process flow.

China since the beginning of the 1970s, in the most primitive iron ore beneficiation process them, and add a fine sieve and then grinding process re-election, making the iron ore product quality from the original 62% to the current 68% For beneficiation process, it is quite a big step forward. Its deficiencies that currently use a fine sieve equipment efficiency remains relatively low, resulting in a large number of fine ore were returned to the mill, the secondary fine grinding, the overall production capacity and cost problems have great impact.

In the beneficiation process in both domestic and overseas markets are faced with the prospect of a better and constantly improve the beneficiation process, to adapt to survive in the competition and development needs, should be based on the key principles to improve efficiency to reduce costs, to develop iron ore crushing mill ore beneficiation process, and constantly improve the level of industrial and mineral beneficiation process, in order to better meet the needs of domestic and international supply market.

Finely ground ore crushing equipment used in the process, Shanghai Zenith have production, including jaw crusher, hammer crusher, impact crusher, vibrating screen, ball mill, etc., equipment have reached domestic leading level
