To be suitable for recycling, waste products consisting of wood always need to be ground down. This operation is indispensable to reduce the size of these wooden waste products and to make them uniform. However, grinding of wooden waste products causes certain difficulties, particularly where impregnated wood such as posts and railway sleepers are concerned.
In actual fact, the metal salts entrapped in the wood cause all cutting tools to quickly become unusable by blunting the cutting edges with which they come into contact. The production of sawdust should be avoided because this causes new treatment difficulties. Moreover, quite frequently, pieces of metal fitting are still fixed to the old wood.

In co-operation with the manufacturer, a new machine has been built on the basis of an existing one; this new machine makes it possible :
to introduce long pieces of wood (posts,
poles…) horizontally in the form of a single piece,
to separate fittings and other foreign
parts present in the wood without damaging the machine or having to stop it,
to convert wooden waste products,
irrespective of their initial size, in a single operation into pieces of a size comparable
to that of shavings, without producing saw dust.
