Preparations Required Before Pressing Iron Concentrate with a Dry Powder Balling Machine

Time：May 18,2021

High-furnace production in the metallurgical industry requires sophisticated materials, just as the particle production process using a high-pressure dry powder balling machine also demands precision materials.

Granular materials should have a specific particle size and an appropriate particle size distribution, along with suitable moisture content, uniformity, and a well-balanced chemical composition—these are essential guarantees for producing high-quality dry powder balling machine pellets.

Unlike sintering, the strength of the particles is primarily due to recrystallization, solid-state bonding, and the pressure generated by the dry powder balling machine itself.

Therefore, the iron concentrate used for pellet production should be as high-grade as possible, with the lowest possible content of impurities.

Iron ore fines should have a certain degree of fineness—this is a fundamental requirement to ensure the smooth operation of the dry powder balling process in a pelletizing machine. Generally speaking, the finer the particle size, the greater the surface area of the mineral powder, and the stronger the intermolecular forces between particle surfaces, which in turn facilitates the formation of uniform pellets.
