Process overview. Grate Kiln systems consist of three major pieces of equipment. The Grate, the Kiln and the Cooler. The object of the process is to transform the pelletized concentrate into hardened pellets that can be used as blast furnace feed or direct reduction furnace feed.
Mar 21, 2015 disc pelletizer, grate kiln proces, Pelletization, pellets, rotating drum, Travelling grate process, 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.
The process was developed in the USA in the 1940s, and the first commercial plant started operation in Babbitt, Minnesota in 1952 (Chernyshev, 1962). The first iron ore pellet plant of the grate-kiln type was established at Humboldt Mine, Michigan in 1960 (Sgouris and Oja, 2008).
Deposit in the grate-kiln process is a well-known problem for iron ore pellet production. In this study, the deposits in a coal-fired grate-kiln plant for hematite pellet production were characterized to reveal their formation mechanisms.
condition & minimizing project cost. It is expected that MECON’s state of art “All Indian Pellet plant” based on Travelling grate (TG) process will meet the above demand. Two major process routes i.e. Travelling Grate (TG) & Grate Kiln (GK) process are adopted worldwide for pellet production where in, TG process has some edge over GK process

The mixed material is subjected to the green balling and further to the Indurating Grate, Kiln-Cooler process where the drying, pre-heating, firing
Pelletizing perfection The pelletizing of iron ore is a critical process in securing high quality in steel mills. WISCO's pelletizing plant is a complex,grate-kiln type process plant that runs with a very fast plant delivery compared to the local Chinese manufacturers.
The second test series included balling of the plant concentrate-bentonite mix in the laboratory continuous balling circuit followed by pot-grate and kiln firing. Changes in pellet plant materials or operations that have proven to lower costs or are in the process of being evaluated are as follows:
Jan 01, 2012 While commercial usage of Peridur in one Vale pellet plant was reported (Kater and Steeghs, 1984; Jiang et al., 1996; Eisele and Kawatra, 2010), no further reports were found on the commercial usage of organic binders until recently, namely, one of the Cliffs' grate-kiln pellet plants was using 100% organic binder to replace bentonite (Oja, 2013).

Feb 12, 2018 Rotary kilns used in cement, pulp mills, lime calcimine plants and a pile of other applications. I’m going to Northern Sweden in 3 weeks where AC supplied a grate kiln pellet plant in 1967 for iron ore pellet making.
As LKAB has two different types of pelletising plant straight grate and great kiln plants the drying process varies slightly. In Malmberget's two pelletizing plants, the entire process takes place on an endless conveyor belt. In Svappavaara's and Kiruna's pelletizing plants, the process takes place in three different machine units

In KOBELCO-Pelletizing Process, Heat treatment stages (Induration section) are carefully separated as Travelling grate / Rotary kiln / Annular cooler and each unit is expected to optimally carry out a specific process function.This increases the plant availability and reduces the requirement for spare parts, resulting in low maintenance cost.
Plant overview Grate-KilnTM iron ore pelletizing system The first Grate-KilnTM 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.
