Komptech Stonefex separator

Komptech Stonefex separator

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.

Patented air flow system

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 minimising maintenance effort. The Stonefex is offered in mobile and stationary versions.

• Reliable separation of stones and inert material with a separation rate of up to 95 percent.
• Throughput up to 100 m³/h with input sizes from 10…20-150 mm (depending on material and loading)
• Wide range of applications thanks to adjustable separation parameters
• Low energy costs thanks to electrical drive of all components
