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 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 sub-processes, or process segments.
Calcination and Pelletizing of Siderite Ore | IntechOpen. The ore to be pelletized may be enriched low-grade iron ore or high-grade powder forms ores which cannot be directly charged into the blast-furnace. The pelletizing process consists of two main parts: raw pellet (green ball) and product pellet.

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
Early laboratory balling and pelletizing tests resulted in balls or pellets superior in quality as compared to production pellets, no matter what the variable being tested. In order to indicate more closely what a material would do for balling and pelletizing in a plant we felt it was necessary to approach the plant conditions. When the commercial ball size was changed from 1 in. to ...
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 8-16 mm in diameter by a pelletizer and hardening the balls by firing with a .

May 27, 2015· 's Reciprocating conveyors are designed to receive unfired "green ball" pellets from the balling disc belt conveyors and transfer them onto .
spheres, or green balls. The green balls are then fed to one of the two pelletising plants, MK3 or BUV, where the pellets are upgraded to the final product of iron ore pellet. The pelletising plants are divided into different zones, i.e. drying zone, pre-heat zone, firing zone, after firing zone and finally a .
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 rubber-lining 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 3.1. Function of Binders Binders are used to improve pellet properties as listed below: • Promoting and facilitating - balling of iron ores in pellet-izing drum or disc; • The improvement of green, dry, pre-heated and fired
Both drums and discs ball the ore to about 9-16mm 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.
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.

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
Typically limestone, dolomite and olivine is added and Bentonite is used as binder. 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
