Both drums and discs ball the ore to about 916mm size. Drums typically have very high recycle rates so have a screening circuit to screen out undersize and oversize pieces to be put back through the drum. Discs usually do not have a separate screening circuit at the disc. Green pellets are then transported to the induration process.
The most commonly employed agglomeration technique is pelletizing by which a mixture of iron ore, water, and binder is rolled up in a mechanical disc or drum to produce agglomerates (green or wet pellets). Figure 1: Iron pellets . The pelletizing process is a process which contains numerous subprocesses, or process segments.
Figure 1 Greenball growth during iron ore agglomeration. Individual iron ore particles are wetted, and pellet ''seeds'' are nucleated. During agitation in the rotating drum or disc, small seeds can grow by consolidation of individual granules and layering of new feed material
The process of pelletizing combines mixing of the raw material, forming the pellet and a thermal treatment baking the soft raw pellet to hard spheres. The raw material is rolled into a ball, then fired in a kiln or in travelling grate to sinter the particles into a hard sphere.
Iron Ore Agglomeration,Sintering and Pelletising,Magnetic .. The purpose of agglomerating iron ore is to improve the permeability of blast . Pelletizing operations produce a "green" (moist and unfired) pellet or ball, which . »More detailed
Reduced steaming can contribute to faster heat transfer, combined with reduced cluster formation, for better breathing. Higher green ball recovery in the balling stage also contributes to energy savings, with less power wasted on recycling of undersized material. Our product is readily miscible with the iron ore .
The balling section of the pelletizing plant at Hoogovens Ijmuiden consists of 7 balling drums. Each with an average capacity of 100 tons of green pellets per hour. In view of these results it was decided to equip one drum at the Hoogovens'' plant with a rubberlining although of a slightly different construction.
Use of Boron Compounds as Binders in Iron Ore Pelletization The Open Mineral Processing Journal, 2010, Volume 3 27 Function of Binders Binders are used to improve pellet properties as listed below: • Promoting and facilitating balling of iron ores in pelletizing drum or disc; • The improvement of green, dry, preheated and fired
green balls. The firing of green balls is dealt with both theoretically (in terms of heat transfer with chemical reaction in a packed bed) and experimentally, followed by a discussion of test requirements and methods. The paper concludes with a short discussion of the utility of testwork in
Iron ore pellets and Pelletizing processes Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 816 mm in diameter by a pelletizer and hardening the balls by firing with a .
green ball in pelletising . agglomeration during the process of iron ore pelletizing. Iron ore agglomeration is a wet agglomeration process, and moist "greenballs" are subsequently dried and heat hardened at high temperatures to make pellets; the presence of binders affects the entire process from greenball formation to .

The green balls produced by a drum are not uniform in diameter. A significant portion of the discharge (about 70%) is smaller than target size and must be returned to the drum after screening. It is difficult Feed Magnetic concentrate Magnet Tailing Raw material Balling drum Screen Undersize green ball Green ball Storage bin Ball mill
Major advantages of "All Indian Pellet plant" by MECON it''s salient features MECON''s state of the art "All Indian pellet plant'''' based on TG process will ensure complete engineering under one roof which will minimize interface related problems involving various engineering agencies.
Jan 01, 2012· Pelletizing differs from other agglomeration techniques in that the powdered ore is first formed into a "green" pellet or ball, which is then dried and hardened in a separate step, usually by heating. Green pellets are made by combining moist ore with a binder and rolling it into balls using either a pelletizing disk or a pelletizing drum.
Calcination and Pelletizing of Siderite Ore | IntechOpen. The ore to be pelletized may be enriched lowgrade iron ore or highgrade powder forms ores which cannot be directly charged into the blastfurnace. The pelletizing process consists of two main parts: raw pellet (green ball) and product pellet.
4 Iron ore pelletizing Energy efficiency The GrateKiln® induration machine is composed of three separate process pieces of equipment. The traveling grate is used primarily to dry and preheat green balls for feeding into the rotary kiln, where they are indurated. Once the green balls are made they are spread out evenly across the grate.
Green Ball In Pelletising. We are a largescale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment, milling equipment, mineral processing equipment and building materials equipment.
May 27, 2015· Pelletizing Reciprocating Conveyors ... them onto the wide belt feed conveyor via a reciprocating head mechanism which creates a relatively even layer of green balls .
Plant overview GrateKilnTM iron ore pelletizing system The first GrateKilnTM system pellet plant was installed in 1960. The plant took iron ore concentrate and produced superior iron ore pellets (which are spheres of high iron content and uniform quality) for blast furnace and direct reduced iron feed. ... Once the green balls are made they ...

Pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additives—anthracite, dolomite—and binders are prepared in terms of particle size and chemical specifications, dosed, and mixed together to feed the pelletizing process; Balling process: the green pellet is the rolled pellet without any thermal process.
Method and Composition For Use in Recycling Metal Containing Furnace Dust. Technical Field. ... Unlike "green ball" pelletizing methods of the prior art, a three day cure period (on the average) is not required or the use of extra heat to calcine the green ball pellets. Where the prior art techniques have achieved 60 pounds of compression ...
