Pelletizing, or balling, carried out through either a disc pelletizer or rotary drum, is a key part of efficiently and sustainably producing steel from iron ore fines of varying sources. FEECO is a leader in feasibility testing, custom disc pelletizers and balling drums, and parts and service support for the iron ore balling/pelletizing industry.
2) Pelletizing on a disc pelletizer. The conditioned material enters the pan, and as the pan rotates, the iron ore tumbles against itself, growing in size. Once the pellets reach their desired size, they exit the pan and proceed to drying. 3) Drying in a rotary drum dryer.

At its core, a rotary dryer is a robust, large-scale piece of equipment that reduces moisture content in materials through heat transfer. The design is straightforward: A large rotating cylindrical drum receives wet material on one end. As this material travels through the drum, it comes into contact with hot gasses, which evaporate the moisture.

2. Grinding process. The copper ore processed into granules is screened by a vibrating sieve and sent to a ball mill for grinding and crushing. Here also need to use an auxiliary equipment – classifier. It can classify and screen copper ore and release copper ore powder that meets the requirements. 3.
In the lateritic ore processing industry for nickel production in Cuba, the ore preparation stages consist of the following operations: Natural drying by arranging the ore in piles and exposing the material to the solar radiation; crushing to a fragments size of up to 100 mm; direct contact drying in flighted rotary dryers to a moisture content ...
The ITmk3 process uses low-grade iron ore and coal (other feedstocks can be used as supplements) to produce iron nuggets whose quality is superior to that of DRI (97% iron content) but is similar to that of pig iron. The mixing, agglomeration, and feeding steps are the same as in the production of DRI or BFs, but the RHF is operated differently.
The dominant process adopted to produce iron ore pellets in China is the grate-kiln process [10–12]. The preheated pellets roll in the rotary kiln and can be sintered uniformly; therefore, it is known that the grate-kiln method yields a superior and more consistent pellet quality compared with the straight-grate process [13].
These are carried out in large rotary-kiln furnaces. Dryers 50 metres long and 5.5 metres in diameter are common, while reduction kilns 5 to 6 metres in diameter and more than 100 metres long are required to handle the large tonnages of ore and to provide the necessary retention time. Next, it is necessary to reduce the oxide to nickel metal.

Drying Bentonite. Bentonite, as mined, typically contains between 25-35% moisture and requires drying to 5% to 12%. This is often accomplished through the use of a rotary drum dryer. While drying can be a fairly straightforward task in mineral processing, bentonite requires special attention, as overdrying risks diminished performance of the clay.
The former mainly selects magnetite ore, and the latter is mainly used for sorting hematite, mixed iron ore and weak magnetic ore. 6.2 Magnetic separation – cation reverse flotation process The grade of iron concentrate increased from 65.55% to 38.89%, the silica content decreased from 8.31% to 3.90%, and the iron recovery rate was over …

Figure 11.30-1 is a flow diagram of crude ore processing. The first processing step is to reduce the diameter of the ore to approximately 1.6 centimeters (cm) (0.6 inch [in.]) in a primary jaw crusher. The crude ore is then passed through a rotary dryer, which reduces the moisture content from between 4 and 10 percent to less than 1 percent.
