Agglomeration Drums - FEECO International Inc.

Agglomeration drums work by tumbling material in a rotating drum in the presence of a binding agent. The binding agent causes the fines to become tacky and allows them to pick up additional fines, forming agglomerates in a process referred to as coalescence. The tumbling action helps to round the agglomerates and create a homogenous mixture.

STRONG IRON ORE GREEN PELLETS. THEORY AND

2017-2-6  Agglomeration of iron ore is commonly done in large balling drums or discs using water together with an external binder as a binding media. The mechanical strength of wet green pellets controls the productivity of the balling circuits and influences the productivity of the subsequent firing process, as well.

Modelling and Control of the Balling Drum Circuit of an ...

1976-9-1  The balling drum circuit as conventionally used in iron ore pelletizing plants is analyzed from a control engineering viewpoint and a simple model presented. An analysis of the model indicates that the “surging” phenomenon generally encountered in these circuits is actually a limit cycle oscillation. With this knowledge, and using classical ...

Iron Ore Agglomeration Processes and their Historical ...

2015-12-28  Pelletizing of iron ore is a method of Swedish origin, patented in 1912 by AG Andersson (Yamaguchi et al., 2010). The process was developed in the USA in the 1940s, and the first commercial plant started operation in Babbitt, Minnesota in 1952. The first iron ore pellet plant of the grate-kiln type was established at Humboldt Mine, Michigan in ...

1985-6-1  Pelletization experiments of fluxed iron ore were carried out using Baharia iron ore (in Western desert, Egypt) and Rifai limestone (located east of Cairo). Fluxed pellets containing 10% and 20% limestone were produced in a laboratory balling drum. It was found that the pelletization kinetics were sensitive to the water content of the pellets.
