VKB - Drag chain discharger

Drag chain dischargers are proven systems for the storage and metered discharge of bulk materials

For small storage units up to 100 cubic metres, we offer you efficient systems with our drag chain dischargers. These consist of a steel construction with two lateral conveyor chains. The transverse feed dogs screwed in between move the bulk material stored on an intermediate floor to the discharge side and transfer it perfectly dosed to the downstream conveyor. Low conveying speeds ensure long-lasting operation. You will benefit from our drag chain dischargers in furnace collection containers, for example, or as a discharge device in low-level bunkers. Scraper floors are also often used as truck reception.

Advantages at a glance

  • Feed tank for firing plants or material receiving station 
  • Low kinetic movement with high discharge capacity
  • Flexible use either above ground or in bunkers 

Convince yourself of our flexibility in the implementation of your requirements.

Waste wood

The processing of waste wood transforms wood waste of various types into a valuable secondary raw material. Besides the recovery of materials, efficient energy recovery is becoming increasingly important as a renewable energy source.

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.
