VST - Star screening machine

High-performance screening of excess lengths

Do you need to screen out excess lengths from your bulk material stream? Our efficient starscreen machines are the answer. These powerful machines are used particularly frequently in sawmills for screening out excess lengths from bark and wood chips. They consist of several horizontal shafts arranged one behind the other and fitted with interlocking screening stars. The rotary motion of the shafts transports the bulk material horizontally. The bulk material falls through the remaining opening between the shafts and screen stars.

Advantages at a glance

  • particularly suitable for screening large volume flows, e.g. wood chips and bark
  • high screening capacity with low space requirement
  • low energy consumption, no jamming
  • low maintenance costs, perma lubrication, optional cental lubrication

All

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.
