SIMETALCIS Intensive Mixing and Granulation    SIMETALCIS Intensive Mixing and Granulation

Siemens VAI Intensive Mixing and Granulation System is a highly economical alternative to conventional sinter raw mix preparation systems, especially when raw materials with a high content of ultra fine materials and high moisture fluctuations have to be treated. Additional benefits are also achieved in the treatment of raw materials with a standard grain size distribution

Intensive Mixer The challenge High homogeneity and permeability of the sinter raw mix are decisive factors for achieving a high sinter productivity and quality at a low energy consumption. With a conventional mixing drum, however, only a very limited homogeneity of the sinter raw mix can be achieved.

Our solution

Siemens VAI therefore developed the Intensive Mixing and Granulation System. The Intensive Mixing and Granulation System is characterized with the combination of a special designed vertical Intensive Mixer (high speed agitating mixer) – as shown at the figure1 - and a horizontal Intensive Granulator installed downstream to the Intensive Mixer, preferably just before the sinter machine feeding system. In specific cases, just a single equipment for intensive mixing and granulation can be installed depending on the raw mix and operational parameters. The sinter raw materials (coarse as well as fine iron ores, additives, dusts, coke, and return fines) are continuously fed to a high-speed intensive mixer where macro- and micro-mixing of the sinter occurs. After the mixer, the material is transported to the granulation drum where the material granulation takes place. The mixing devices can be individually adjusted to actual requirements.

Good reasons for SIMETALCIS Intensive Mixing and Granulation

No pre-blending (blending yards) required (only bunker blending system)

Lower solid fuel consumption, because of best possible fuel distribution

Even with higher amount of iron ore concentrate (pellet feed) the productivity is maintained

Economically reuse of revert materials, i.e. dusts, sludge, scales, and others

Lower electric energy consumption even when the sinter machine is operated with high bed height
