Preparation of pellets and micro-pellets
When processing raw materials for the production of green pellets, ultrafine ores are mixed with binding agents (e.g., bentonite) and aggregates (e.g., limestone or dolomite).
The preparation in the EIRICH Intensive Mixer is performed in continuous operation.
This results in the following advantages:
- Low consumption of binding agents
- Reduced energy requirement
- Higher green strength of pellets with a low recycling quota
- High and constant homogeneity of material at throughput rates up to 1,400 t/h
- High operational reliability with little maintenance
- Narrow grain size range / uniform quality
- Low wear
Preparation of sinter mix
The benefits of EIRICH mixers in the sinter industry have been proven true in many projects and can be summarized as follows:
- Completely homogeneous sinter raw mix
- High and even sinter bed permeability
- High productivity of the sinter plant even with high portions of fine and ultrafine iron ore
- Reduced energy consumption
- Low solid fuel consumption
- Equalized burn-through zone
- High and stable sinter quality
- Less return material
- High availability
- Throughputs up to 1,400 t/h
Recycling of valuable residues
With the EIRICH mixing system, residues like dusts and sludges from sinter plants, blast furnaces, cast shops, BOF plants and electric arc furnaces are effectively prepared.
The EIRICH intensive mixer is able to manage several processing steps one at a time:
- Mixing
- Moistening / moisture distribution / moisture removal
- Dispersing
- Compacting
- (Pre-)granulating
- Reacting
- Cooling
Advantages of the EIRICH mixing system:
- Excellent mixing results
- Stable properties of the intermediate product
- Flexible system able to cope with even greatly
varying properties of the residues
- High wear resistance
- Self-cleaning
