Jan 04, 2018· In 1948, a pilot plant owned by Erie Mining Company began operation utilizing a drum pelletizer to produce taconite pellets. The balling drum circuit for iron ore is shown in its simplest form in Figure 6. The circuit consists of the rotating drum, which has a length-to-diameter ratio of 2.5 to 3.5, a vibrating screen and a recycle belt conveyor.
Drums are used primarily for the preparation of fine ores in systems with high process throughput rates, e.g. iron ore. Pelletizing drums always run in continuous operation. Granulating mixers The mixing systems that can be used are pushing mixers and throwing mixers, which are both available in a multitude of designs and variations.
In the pelletizing plant, a clay mineral, bentonite, is added as a binder in the iron ore concentrate. Pellets with a diameter of around 10 mm are then formed in large, rotating drums. When the pellets have been rolled, they are transported for drying and pre-heating.
Besides iron ore agglomeration, these pelletizers can also be used for other materials such as copper ore, gold ore, coal, and fertilizer [12]. The rotary drum pelletizer was first used for taconite pellets in the early 1940s [14, 18]. A large drum-shaped cylinder is slightly elevated at one end, approximately 3–4°.
Outotec Pelletizing Drum is used to produce uniform agglomerates from fine materials. The feed material can be fine concentrate or waste material, for example from the iron making process. Pelletizing – for chromite, manganese, or iron concentrate for ferroalloys and steel making processes. Heap leaching – for agglomeration of ore fines ...

Sep 10, 2018· For the iron ore concentrate, the GBT-10322.1-2000 standard stipulates we can use the auger sampling system to sample unless the auger sampler can reach the bottom of the iron ore storage and the auger hopper which is filled with iron ore. TOP-SAMPLER promises that our all sampling systems can meet this requirement and the sampling procedure is random and effective.
Mar 21, 2015· Understanding Pellets and Pellet Plant Operations. Pelletizing is an agglomeration process which converts very fine grained iron ore into balls of a certain diameter range (normally 8mm to 20 mm, also known as pellets. These pellets are suitable for blast furnace and direct reduction processes.
The iron pelletizing process is often associated with low grade iron ore following a range of liberation techniques to prepare and make suitable for the blast furnace. In summary, pelletizing is achieved by combining the iron ore with water and a specific binder which is then rolled up in drum to produce relatively uniform pellets which can ...
Jul 11, 2018· The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing …

Pellet (Iron ore) - Mining Fundamentals. Iron ore pellets are marble-sized balls of iron ore that are fused with clay for transportation and used in steel manufacture. The process of making pellets from iron ore is called pelletizing. The manufacture of steel from low-grade iron ore involves processes like mining, crushing, separating ...
In addition to total iron in the pellet, its reducibility also impacts the overall yield. Several factors influence the hot reduction behavior of the oxide pellet in the direct reduction shaft furnace. The specific mineralogy of the ore, as well as the fluxed basicity of the pellet (ratio of basic-to-acid components) will determine the degree ...
