Belt weigh feeders

The DLN Belt weigh feeder

Operating principle and use

The belt weigh feeder extracts a product from a storage hopper through the constant cross-section and according to a fixed reference flow-rate (set point), adjusts the extracted volume by varying the belt speed in such a way as to keep a constant weighed flow-rate.

The DLN belt weigh feeder is used for the continuous weighing and feeding of materials with normal or difficult flowability.

  • Cement Industry: Limestone, Clay, Pyrite, Clinker, Gypsum, Slag…
  • Steel Industry: Iron ore, Coke, Additives
  • Coke production: Coal, Additives
  • Chemical Industry: Raw and humid phosphate, Sulphur, Potash, Urea, Fertilizers, Carbonate
  • Building materials: Plaster, Lime, Clay, Sand, Barite, Manganese, Grits
  • Aluminum: Petrol coke, raw and burnt scraps, Pitch, alumina, lime…
  • Tobacco: Tobacco and Scaferlati

The DLF Belt weigh feeder

Operating principle and use

The DLF belt weigh feeder extracts the material from a feed chute colling "calming chamber" through the constant cross-section and according to a fixed reference flow-rate (set point), adjusts the extracted volume by varying the belt speed in such a way as to keep a constant weighed flow-rate. In the “calming chamber” the material is slowed down and de-aerated.

The DLF belt weigh feeder was designed especially for free end very free flowing materials. The belt conveyor is extended to incorporate the “calming chamber” where the material is slowed down and de-aerated.

This weigh feeders is used in:

  • Chemical Industry: Crushed dry phosphate, powdered dry clay,
  • Building materials: Hot and dry plaster, Silica, Manganese
  • Aluminum: Fine of petrol coke and crushed coal,
  • Cement Industry: Row meal, dry trass
  • Coke production: Coal, Additives
  • Petrochemical: Polyethylene and polypropylene

The DLV Belt weigh feeder

Operating principle and use

The belt weigh feeder extracts a product from a storage hopper through the constant cross-section and according to a fixed reference flow-rate (set point), adjusts the extracted volume by varying the belt speed in such a way as to keep a constant weighed flow-rate.

The DLV belt weigh feeder was designed especially for poor flowing and sticky materials. The belt conveyor is extended to incorporate the “buffer hopper” with vertical anti-sticky walls where the material is slowed down and de-aerated. This weigh feeders is used in:

  • Cement Industry: Humid Limestone, Clay, Pyrite, Gypsum,
  • Steel Industry: Iron ore,
  • Chemical Industry: Humid phosphate and sulphate,
