The Disc Filters belong to the side feed group and have been around for many years. They are generally used in heavy duty applications such as the dewatering of iron ore taconite, hematite, coal, aluminum hydrate, copper concentrate, pyrite flotation concentrates and other beneficiation processes. The high time for Disc Filters was in the 60''s when the metallurgical industries were booming and
Introduction to iron ore agglomeration Agglomeration is the process of particle size enlargement and most commonly refers to the upgrading of material fines into larger particles. Agglomeration types: Briquetting Briquette Extrusion Extruded briquetting Sintering Sinter Pelletizing Pellet n) Nonn) 47th Ironmaking . Patent (1914): JE Greenawalt / USA // rectangular tilting pans
disc pelletizer, grate kiln proces, Pelletization, pellets, rotating drum, Travelling grate process, 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

· Fu et al. (2012) investigated the role of bentonite added in a mix of iron ore, large beta filterNickel, PIXcel3D detector and CuKα radiation (λ = Å), operating at 40 kV/40 mA. The incident beam path was collimated by employing Soller slits of rad, a fixed incident beam mask of 10 mm, an antiscatter slit of ½°, and a divergence slits of ¼°. Antiscatter slits of mm
· Iron ore beneficiation is a multistage process that raw iron ore undergoes to purify it prior to the process of smelting, which involves melting the ore to remove the metal process of iron ore beneficiation has two complementary goals and these define the methods used to refine it. The iron content of the ore needs to be increased and gangue, which is native rock and minerals of
In two different iron ore processing plants, it was demonstrated that when magnetite concentrate was filtered to prepare it for use as pelletization feed, the moisture that remained in the filter
There has been a drop in the process efficiency in the filtration due to which the filter cake moisture was more than that of filter cake produced using beneficiated iron ore concentrate. This has

Whether you are looking to eliminate dust, convert a waste to a marketable product, or improve product characteristics, we can design and manufacture agglomeration equipment to create a highly efficient process that produces the product you''re looking for. What Can Agglomeration do for
oil filter in mineral processing industry of application. With the increasing impoverishment of mineral resources, in order to improve the comprehensive utilization rate of mining, it is necessary to grind the ore more finely, so as to improve the mineral processing index and product quality. The metallurgical industry requires high grade and low moisture content of raw materials before
Iron Ore Processing for the Blast Furnace (Courtesy of the National Steel Pellet Company) The following describes operations at the National Steel Pellet Company, an iron ore mining and processing facility located on the Mesabi Iron Range of Minnesota. Creating steel from lowgrade iron ore requires a long process of mining, crushing, separating, concentrating, mixing, pelletizing, and
Agglomeration is the formation of aggregate by the sticking together of feed and/or recycle materials, and it includes the formation of agglomerate nuclei. The main objective in agglomerating fines being the conversion of ores, minerals and chemicals of undesirable fineness into agglomerates characterised by a size consistency desirable for subsequent use or processing. In metallurgical

iron ore. His process involved grinding taconite to remove gangues and upgrading the iron ore (, an ore beneficiation process). The resultant highgrade ore is in the form of fine particles, as small as or less, which are not suitable for sintering. This issue led to the use of pelletizing. Pelletizing plants are expected to play an important role in an era when the global reserve of
The most common filter in the iron ore industry includes 12 discs, 9 feet in diameter, therefore a sq. ft. filtration space (120 m, or 120 sectors of 1 m). The advantages of Metal 7''s vacuum disc filters . Optional features are available including. The ore, in the form of slurry, is brought to the filter''s tank in which a number of discs rotate at a regulated speed. Each disc is
· Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of highgrade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron agglomeration

These forces responsible for the agglomeration of iron ore fines are generated in the balling disc due the rotational movement in the balling disc. When the solid particles come in contact with water, the ore surface is wetted and coated with water film. Because of the surface tension of the water film, liquid bridges are formed.
This process generates iron ore filter cake which needs to be pelletized to be used in the steel making process. Also during the processing of high grade iron ores which don''t need beneficiated, fines which are generated can be pelletized and used instead of being disposed of. Iron Ore Pellets are formed from beneficiated or run of mine iron fines. The iron is usually ground to a very fine
Such conditions are obtained in inclined disks (pans), rotating drums, powder mixers, and fluidized beds. In pressure agglomeration, enlarged entities are formed by applying external forces to essentially dry particulate solids in more or less closed dies that define the shape of the agglomerated product. Since the level of force applied is the most distinguishing factor, there are low
In two different iron ore processing plants, it was demonstrated that when magnetite concentrate was filtered to prepare it for use as pelletization feed, the moisture that remained in the filter cake had greatly elevated levels of cations compared to the water removed by the filtration process. In particular, calcium concentrations in the filter cake were 565 times higher than in the filtrate
