Premixing
- Homogeneous distribution of all materials in the mix as well as a uniform coating of lime on the sand
- Intensive wetting of the lime with water
- The full surface of the sand grains is activated to form calcium silicate
- Clay agglomerates, which inhibit the formation of high-density calcium silicate with fine pores, are broken down
- Lime agglomerates are reliably separated
- Uniform brick structure when light aggregates or fly ash are mixed in
- Outstanding, reproducible mixing quality
Secondary mixing
- Reliable separation of reactor material agglomerates
- Accurate control of the moisture for pressing
- Continuous material stream up to brick removal on the press
- No streaking when pigments are mixed in
- Adaptation of the mixing power to changes in pressing output associated with different brick sizes
