Sand lime brick

Future-proof your production environment with products/services from a single source

The patent for the production of sand-lime brick has existed since 1880. EIRICH has contributed to the sand-lime brick success story since its earliest industrial beginnings.

We supply material preparation equipment for state-of-the-art wall construction material

  • mixing systems
  • a full range of conveying, weighing and feeding equipment
  • control and process control systems
  • machinery and systems engineering
  • a broad service portfolio

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
