Backmix filling station

Complete filling to the upper edge, as well as targeted over-filling in sections of the mold using back mix feeding.

Station 4:
Backmix filling station

Advantages

  • Easy operation
  • High dosing accuracy
  • Reproducibility of overfilling
  • Less facemix compaction and displacement
  • Lower manufacturing tolerances, improved coplanarity of the products
  • Quick recipe-related adaption to a wide range of moulds
  • Simplified machine cleaning

Filling the mould with the earth-moist backmix. Backmix feeder for complete filling of the mould up to the upper edge, and targeted overfilling in certain parts of the mould. Electronic overfilling ensures a precise and even slab thickness. Displacement of the facemix is avoided.
Equipped with:

  • Mobile group consisting of material silo, conveyor belt and filling pocket
  • Mobile group with adjustable forward and reverse speed
  • Material silo with level sensor for communication with the mixing plant
  • Frequency-controlled belt conveyor drive unit, for take-out of the material from the material silo and for loading the filling pocket

During forward movement, the mould is filled with backmix; during the backward movement, it is overfilled by means
of electronic overfilling and the surplus material is removed by scrapers. The X-Y-axis regulation allows for adjustment of a speed-independent and freely programmable overfilling curve. The complete unit can be moved for easy cleaning.
