VDB, VZB – Hydraulic discharge device (pushing cylinders)

The Vecoplan traction pull rod dischargers are specially designed for high discharge capacities

Do you need a pull rod discharger to discharge bulk material such as wood chips, sawdust, RDF, shredded film and plastics from your silo, deep bunker or storage boxes? Our VDB and VZB series are efficient systems with high performance. Each drive unit works independently with its own control system and optional energy-efficient frequency converter.

Advantages at a glance

  • Available as standard version (VZB) or delta version (VDB)
  • Each conductor segment can be controlled independently 
  • Optionally with energy-efficient frequency converter for metered discharge capacity
  • Available as "non-trafficable", "trafficable" and "force-reduced", for a particularly small load introduction into the foundations

All

Bark

Bark can be thermally recycled as fuel and further processed into bark mulch or bark litter.

Wood chips

Wood chips are used in the manufacture of chipboard and medium-density fibre (MDF) boards. They are also used as fuel in heating plants, in combined heat and power plants and in gardening and landscaping.

Wood and milling chips

Planing and milling chips are usually reground and then used as insulation material or, for example, in the production of pellets.

Straw

Grain straw is used in biogas plants. The material is also used in the form of straw pellets for alternative heat generation. Straw is the primary material used in the production of bioethanol.

Coconut shells

Briquettes made from coconut shells burn longer than wood and can be used in crop-growing countries to replace wood from life-sustaining forests. The material is also suitable for use as a fuel in biomass plants and boiler plants. The fibres in coconut shells have excellent insulating properties and are used to this end.

Grasses

Some grasses, such as miscanthus and switchgrass, are called biomass grasses because of the large amounts of biogas they can produce.

Residual forest wood

Residual forest wood is often the raw material for mulch, but it is also used as animal feed. In addition, it is used as fuel in biomass CHP plants (combined heat & power plants).

Green waste

Green waste is used as co-substrates for soil improvement and is increasingly incinerated for energy in biogas plants. Coarser fractions of wood can also be made into mulch.

Film

Regranulates can be created as secondary raw materials from packaging, agricultural film, composite film, etc. The treatment process for this includes shredding technology, separation and sorting technology, washing and subsequent extrusion.

Packaging

As the demand for high-quality regranulates increases, closed-loop recycling is playing an increasingly important role in the material recovery of plastics, and this is why shredding is a critical process step since it is a preliminary stage for the subsequent sorting of recyclable materials.

Film

Waste generated during production should, if possible, be returned directly to the internal production cycle without any losses or loss of quality. If such in-house recycling is not possible due to company-specific constellations, external recycling companies can also process film waste.
