Pelletizing Plants

Pelletizing is the process through which iron ore fines are transformed into an agglomerated form called “iron ore pellets” suitable for use in an iron-making furnace at a steel mill, such as a blast furnace or electric arc furnace.

In its end product form, a typical iron ore pellet is roughly spherical in shape, measuring from 6 mm to 16 mm in diameter and having a crushing strength of over 200 Kg, although some variations in these typical parameters can be specified and targeted in the design process.

An iron ore pelletizing plant is typically comprised of a series of unit operations in a specific process sequence.
It can be divided into:

Feed preparation
Mixing (Iron ore + additives)
Balling (“green” pellets are produced)
Indurating (firing and hardening and producing the “fired pellets”)
Product handling (fired pellets may be screened for end user size requirements)

BOLLFILTER for fuel filtration

BOLLFILTERs can be installed to filter the various fuels used by the furnace during the induration phase:
Indurating is the process of taking the green pellets and hardening them through a high temperature furnace application. The fired pellets are hardened so that they can withstand transportation and handling per the end user requirement.
