The Hammer Mill series W is specially designed for grinding moist and wet wood with more distance between the side wall and screen. This mill grinds chopped soft and hard wood with a feed size up to standard G50 wood chips, and a water content up to 60%, in one step to a fineness required for wood pellets. The W series consists of four sizes with a drive-power range between 75 and 250 kW.

The use of waste wood as a substitute fuel in coal-fired power plants is gaining enormous importance in the energy transition. The Wide chamber mill W plays an important role in this context. You can find out more in our article Waste wood as a substitute fuel and alternative to coal.
