Coarse Powder Mill Simple, Compact, Portable, Convenient European Type Coarse Powder Mill can process soft or hard ores secondarily or finely whose compressive stress below 320Mpa. It .
process kilns are shorter. Wet process and long dry process pyroprocessing systems consist solely of the simple rotary kiln. Usually, a system of chains is provided at the feed end of the kiln in the drying or preheat zones to improve heat transfer from the hot gases to the solid materials. As the kiln
Iron ore extraction is mainly performed through open pit mining operations, resulting in signi ficant tailings generation [2]. The iron ore production system usually involves three stages: mining, processing and pelletizing act ivities. Of these, processing ensures that an adequate iron grade and chemistry is achieved prior to the pelletizing stage.

2 Pelletization of Iron Ore The Pelletizing Process Before iron ores enter the blast furnace, it is necessary to remove a great portion of the mineral ballast components by graining. To remove these pollutions, concentrates are very fine grained and agglomeration is therefore necessary. Agglomeration can be achieved by sintering and pelletizing.
