In recent years, the domestic research institutes to strengthen research on powder iron ore roasting technology and the so-called - flash firing technique, namely the use of rotary kiln calcination technology enables rapid powdered iron ore magnetic roasting. The iron equipment selection test Key iron concentrate grade can improve a lot.

In short iron selection equipment industry plays a vital role in the national economy, the efficient use of resources of iron ore beneficiation workers a daunting task. Domestic institutions and mining enterprises over the years done a lot of work in this regard: a lot of achievements in the magnetite beneficiation technology, hematite mineral processing technology, such as a variety of weak magnetic field magnetic separation equipment and anti-flotation process iron ore concentrates to mention quality degradation plays a very significant for mineral processing equipment in general is a new challenge, which requires excellence, the development of automation, however, has a very important role in the beneficiation process, can reduce the beneficiation process labor costs, simplify operation, improve labor productivity, reduce energy consumption, stable product quality. Therefore, processing automation is into the production practice, had become one of the essential element of modern dressing.

However, if you want to achieve true mineral processing equipment automation, we must first realize the real-time inspection of the dressing process, deviations occur when the process and the nature of the ore mineral processing equipment, process must be adjusted according to the nature of the ore. Therefore, there must be a correct process must have the right experience and historical data as a guide.
