Iron Ore Pelletization - FEECO International Inc.

Pelletizing, or balling, carried out through either a disc pelletizer or rotary drum, is a key part of efficiently and sustainably producing steel from iron ore fines of varying sources. FEECO is a leader in feasibility testing, custom disc pelletizers and balling drums, and parts and service support for the iron ore balling/pelletizing industry.

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.
