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.
The balling equipment that can be either a disc or a drum produces green pellets in a variable size distribution. 3.1. Balling disc or disc pelletizer Figure 3 schematically shows a laboratory disc pelletizer. The balling disc basically consists of a pan with a peripheral wall, which rotates with a certain inclination to the horizontal [1]. In
It is original and peculiar with largescale disc-pellet machine and designed on the basis of the largescale disc-pellet machine that is used in industries like iron and steel industry, chemical
The grinding work done to smoothen out some parts of the . Fig. 1. The front view of the balling disc machine. Fig. 2. The side view of the balling disc machine. IX. DISCUSSION OF DESIGN. From the result of the experiment performed, it is observed that the balling disc machine produced different sizes range 6-25mm of coal pellets.
Jan 01, 2019· After grinding, the fuels were available to be mixed with pellet feed, limestone and bentonite to prepare the green mixture, for balling and at last burning. The Sponsor of this study, in its operations has as target of specific surface area of at least 5000 cm 2 /g, and 40% passing through the 44 μm sieve for anthracite fines. As there was no
Pellet Plant produces Pellets using Iron ore and additives such as limestone, lime stone/ additives is added with iron ore fines for grinding in ball mill. 2.2.2 Pre-treatment process of additives classifies green balls by itself, reducing the amount of pellets returned. The disc operation can easily be adjusted for varying raw material
Formation of green balls or pellets Green pellets with a size range of 8 mm to 16 mm are prepared in a balling drum or in a disc pelletizer. Disc pelletizer is preferred for the production of the quality green pellets since in the disc pelletizer it is easy to control the operation with minimum of foot space.

pellets. Acid pellets are produced from iron ore and a binder only, and flux pellets are produced by adding between 1 and 10 percent limestone to the ore and binder before pelletization. Pelletization generally is accomplished by tumbling moistened concentrate with a balling drum or balling disc. A
Jan 01, 2015· Similar procedures are currently used in some pelletizing plants in India as well, especially in Tata Steel's 6 Mtpa straight grate pellet plant, which is the first in the world to use dry grinding to achieve specific surface areas of 2600–3000 cm 2 /g (Paul et al., 2013).
Mar 20, 2013· Pellet growth is controlled by the small amount ofwater sprayed in the disc and the adjustment in the disc rotational speed.A pellet plant contains a series of balling drums where the iron ore concentrateis formed into soft pellets, in much the same manner that one rolls a snowball,to make a pellet about the size of a marble (between 1/4" and 1
Grinding improves pellet quality by reducing air spaces between particles, allowing closer surface to surface contact for a given volume of feed; i.e., it increases bulk density. Large pieces of any ingredient in a feed formula result in weak spots in the pellet, especially if these are fibrous or bony.
Jun 01, 1999· This pilot plant is provided with at least roller presses 5, ball mills 2 and 2a, hydrocyclones 11, dryer 12, a thickener 6a, homogenizing tank 7a, a vacuum rotating filter 8a, mixer, pelletizing disk 9 and a pilot furnace 10 for firing the iron ore pellets.
Pellet plant (4·2 MPta capacity) of JSW Steel Ltd imports iron ore fines from different mines to produce pellets for its Corex and Blast Furnace plants. grinding in open circuit ball mills to
The plant used iron ore concentrate as input and produced superior iron ore pellets for blast furnace and direct reduced iron feed. Since then, Grate-Kiln Systems have been used for over 50
the maximum utilisation of disc surface for rolling action of the material. In commercial plant the disc speed is generally of the order of 6-20 rpm for the diameters ranging. from 3 to 6 meters. Disc Diameter Due to simplicity of operation, the pelletising discs have large variations in its diameter.
The Autofill system avoids direct contact with LN2 and makes cryogenic grinding very safe. Its versatility (cryogenic, wet and dry grinding at room temperature) makes the CryoMill the ideal grinder for quantities up to 20 ml. You may also be interested in the High Energy Ball Mill Emax, an entirely new type of mill for high energy input.
The Planetary Ball Mill Pulverisette 5 allows fast and very fine grinding of hard to soft material, dry or in suspension, down to colloidal fineness. It can also be used for mixing and homogenising of emulsions and pastes. Grinding capacity of up to 8 samples per operation.
Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces.They typically contain 64–72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.. The process of pelletizing combines mixing of
The Vibratory Disc Mill RS 200 is suitable for the extremely quick, loss-free and reproducible grinding of medium-hard, brittle and fibrous materials to analytical fineness. The instrument runs steadily and smoothly, even with heavy grinding sets, at maximum speed thanks to the new Stabilized-Plane-Drive.
cone crushers, rod mills, and ball mills; C concentrating of the iron ore by magnetic separation or flotation; C pelletization by wet tumbling with a balling drum or balling disc; and C indurating using a vertical shaft furnace, straight grate, or grate/kiln, and material handling (transfer, pellet cooling) of the indurated pellets.
