Waste wood processing for recycling

Recycling renewable resources such as wood plays an important part in environmental protection. Wood is often used for pallets, chipboard and demolition wood, etc. At the end of its life large quantities of it end up as waste wood on recycling on your premises. Then particularly clean waste wood can be recycled and reused as a new product (e.g. recycled chipboard).

The waste wood shredding process

We build our reliable industrial wood shredders on more than 40 years of experience. This ensures the production of a homogeneous granulate with day in, day out performance. We configure the wood shredder or chipper for woodworking scrap. Exactly according to your needs. Transported to where you need it. Regardless of how you are planning to use the wood chips. The reduction in size from the waste wood also reduces your disposal, transport and storage costs.

1) The primary shredding process

After the wood has been sorted in accordance with the waste wood grades, A1 and A2 waste wood is processed in the wood shredder. The shredding system, pending the setup, can shred any type of wood waste down to a homogenous wood chip and separate nails and other metal parts from the material.

2) Magnetic separation of ferrous metals

In the second step, the separation of ferrous metal parts is removed from a stream of chips. Separation can be done in three different ways pending the setup: Either with a overbandmagnet, installed perpendicular to the material flow. With a drum magnet within the sucking system or with a drum separator installed before re-shredding. The permanent magnet removes all ferrous particles from the material.

3) Re-shredding – granulation of the shredded wood waste

Pending your preferred size of wood granulate, the shredded wood waste, now free of ferrous metals, enters the second re-shredding stage. This extra step is only required when a homogenous wood granulate of down to 6mm is needed. The final product is a to ensure that the recycled material is of high quality throughout to produce chipboard, animal beading and briquettes.
