Iron ore is a crucial raw material for steel enterprises. While, only few of rich iron ore could be directly used for iron making or steel making. For the majority of ores with 50% grade, they need to go through process procedures such as crushing, grinding, magnetic classifying and floating classification before being used for smelting. 

With the development of economy and social progress, steel enterprises have a increasing demands for high quality iron ores so it is with the demand for iron ore resources. However, ores that are easy to classify is decreasing. With more and more low-grade ores and decreasing of rich-grade ores, complicated composition of iron ore, thin granularities spread, all these become the main characteristics of current situation of our nation’s iron ore characteristic, which posing a great difficulties for ores classifying. As a consequence, this needs advanced technology, process and equipment to push the development and usage of low-grade ores.

How to make the classifying procedures more efficient, environmental-friendly and economical is the crucial development points. Crushing procedure is the first process for ore classifying and it is a process of great importance. If the crushing effect is not ideal, the consequent process can not smoothly carried out. Hence choosing high efficiency with low energy consumption crushing equipment directly related to the economical benefit of the dressing plant.
