Sep 22, 2013· The process of pelletizing iron ore on disc pelletizers is mathematically modeled. Different methods of regression analysis are used to describe the pelletizing operation, and the equations that are obtained are compared with one another. The objective function is optimized based on the yield of green pellets of the class (–14+5) mm.

Disc pelletizer is widely used in the agglomeration process to form powdered iron ore into iron ore green pellets. The pellet size distribution (PSD) is one of the major measures of product quality.

Iron Ore Pellet Plants Being counted as the leading manufacturer, supplier and exporter of the industry, we are presenting a wide assortment of Pellet Plants. These products are reckoned amongst the clients for their precise use and durability.

were prepared by mixing the iron ore fines, limestone, and bentonite and coke breeze as per Table 2. Green pellets were prepared using laboratory scale balling disc. The green pellets were prepared in such a way that it should consist of ~97% –16+8 mm size range pellets. The details of balling disc are as follows: Disc diameter: 450 mm

Introduction to Iron ore Pellets and Pelletizing processes Pelletizing is a process which involves mixing of very finely ground particles of iron ore fines having a size which is less than 200 mesh (0.074 mm) with additives like bentonite and then shaping them into near oval/spherical balls having size in the range of 8 mm to 16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.

Build-up agglomeration is a well-established method for manufacturing granules or pellets from powdery mineral raw materials. Companies regularly have to ask themselves what the best, easiest and most cost effective way is to manufacture their required products. Mixers, disk pelletizers and pelletizing drums are available for build-up ­agglomeration.

The reducibility of iron ore pellets of a specific chemistry can be improved by the optimization of physical parameters such as induration temperature, improving size distribution of fines ...

Disc Pelletizer. The formation of raw iron ore pellets, also known as pelletizing, has the objective of producing pellets in an appropriate band of sizes and with mechanical properties high usefulness during the stresses of transference, transport, and use. Both mechanical force and thermal processes are used to produce the correct pellet ...

Use of iron ore pe llets not only increase the productivity of the plant but also produce good quality iron. So it is essential to know about the various factors which affect the reducibility of th e iron ore pellet. In our project we aim at studying the effect of size of iron ore pellet on …

Iron ore pelletization process using a rotary drum pelletizer. Disc pelletizers are also used extensively worldwide. The advantage of the disc pelletizer is that there is no recirculation. The desired blend is fed to the pelletizer, which is a large disc inclined at 40–60° to the horizontal ( Figure 1.2.7 ).
