The Stonefex stone separator gets stones and other inert
material out of biomass fuels dependably and with high
separation efficiency. The input material is the useful biomass
fraction from a screen, like woody green cuttings, screen
overflow from compost or forestry chips.
A patented system of pressure and suction blower generates
exactly the right air flow in the separation chamber to
remove stones from the wood. The blowers and discharge
conveyors are electrically powered, reducing energy costs
and minimizing maintenance effort. The Stonefex is offered in
mobile and stationary versions.
