The balling equipment that can be either a disc or a drum produces green pellets in a variable size distribution. 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
Unit Operations For Iron Ore Pellet Plant. Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a. Manual Jumbo Rocket Boomer 282.

The proportioned mix is then mixed in vertical mixer supplied by M/s EIRICH from Germany and the mixed proportioned is fed to Balling Disc building (Pelletising). The Balling building is provided with 6 sets of 6 m dia balling disc with 5 in operation and 1 standby. % to % water will be added in pelletising process so as to realise optimum value of water content in the mix for pelletising and green pellets are
Pellet Plant has 2 sections Balling 2. Induration Role of Green Balling section is to produce green pellets from concentrates. Induration section burns green pellets around 1250 C to increase compression strength from 1 kg/green pellet to pellet of 150kg/ burnt pellet . For Green Balling, a Balling Drum or Balling Disc is used.

Hamersley Irons pellet plant at Dampier involves ore drying, dry grind ing in ball mills, disc balling and, indurating by use of the straight grate system. After five years of operation, the plants output has been increased from the design capacity level of 2 to Steps taken in equipment modifica tion, improvements...
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. The configuration of iron ore pellets as packed spheres in the blast furnace allows air to flow between the pellets, decreasing the resistance to the air that flows up through the layers of material during the smelting.
wet grinding mill operation pellet plant. In particular ball milling is one of the important unit operations in the iron ore balance model in the optimization of a fullscale ball mil circuit grinding pellet fines a linear population balance model in wet grinding systems was established to appraise the plant scale optimization via laboratory scale grinding mill
21/03/2015#0183;#32;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

Automation System for Pelletizing disc The control of the angle of Pelletizing disc in an Iron ore Pellet plant is, disc to . Drum and Disc Balling of Iron ore Get price
Iron ore pellet plant: Material: Fine ore powder: Dia. of balling disc. 3~7 m: Turning speed of disc. 2~ r/min: Inclined angle of disc. 40~55 degree: Production capacity: 3~120 tph #215;
10/07/2017#0183;#32;Balling process: the green pellet is the rolled pellet without any thermal process. It is obtained under strict control of moisture and has a spherical shape and diameter of 816 mm; Induration process: the green pellets are hardened in a high temperature processing at controlled heating rates, and aiming to achieve the physical and metallurgical requirements for handling, transportation, and
Pellet Plant produces Pellets using Iron ore and additives such as limestone, bentonite, coke, anthracite coal, quartzite which are passed through balling disc/drum and the green pellets so formed are passed through a furnace either straight grate or rotary kiln to produce High Grade Pellet which are used in Steel
06/10/2017#0183;#32;Typical pellet plant using disc pelletizer as balling technology. from industrial to developing countries but there is an increase of iron ore processing operations in mining areas such as
Ball Mills in the plant are fed with highgrade iron ore concentrate and highgrade iron ore fines, which are ground into the required size. The products from this process are used to make green balls. Additives such as lime and bentonite are combined with the iron in a homogenous mixture before being sent to a balling disc to make the green balls. To ensure that quality is always maintained, these green balls are
A balling disc, on the other hand, classifies green balls by itself, reducing the amount of pellets returned. The disc operation can easily be adjusted for varying raw material conditions by changing the revolution, inclined angle and depth of the pan. Indurating process The firing of pellets
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. The disc pelletizer is an inclined pan having around 5 metres (m) to m diameter. It rotates at around 6 rpm (rotations per minute) to 8 rpm.
A number of compressive tests were conducted on iron ore pellets obtained from the Samarco pelletizing plant located at Ponta Ubu Brazil. These pellets are formed by disk pelletizing of a mixture consisting of hematite iron ore (particle size less than 50 #181;m) water and lime they are hardened in a travelinggrate furnace and the nominal diameter varies between 9 and 16 mm.
