When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.
On the one hand, increased efforts in iron-ore beneficiation to enhance the iron level in raw materials lead to the ever-decreasing grain size of iron ores. On the other hand, dominating shaft technologies such as the MIDREX direct-reduction process require a complementary agglomeration step to transform the iron ore concentrate into a well ...

ROTARY DRUM DRYERS & COOLERS. As a wet process, pelletizing typically requires a drying step. This is frequently carried out in a rotary dryer, a high-capacity dryer that utilizes a cascading motion to dry pellets, while also rounding and polishing them as they tumble through the drum.In some cases, a rotary cooler may follow the dryer to cool material prior to packaging or storage.
