Each kind of plant can be equipped or not with a concrete mixer, identifying WET concrete batching plants (provided with concrete mixer) and DRY concrete batching plants. WET batching plants allow to blend aggregates, cement, water and additives guaranteeing a better concrete quality and optimizing water/cement ratio. Euromecc produces three types of concrete mixers with cutting-edge mixing technologies: MEB double shaft mixers, MEP planetary mixers, MEC continuous mixers.

 

Analyzing the type of production of the plants are picked out plants for continuous production, equipped with continuous mixers, and plants for cyclical production, equipped with double shaft and planetary mixers.


Euromecc concrete batching plants can be equipped with:


  • bins for bulk material storage (at least two bins)
  • conveyor belts for bulk material handling (aggregates)
  • Automation and management system
  • Silos for cement storage (including silos accessories)


According to material produced, plants are divided into: ready-mixed concrete plants, plants for precast concrete, plants for cement mixture.
