Choppers and counterknives for crushing wood

The best from experience: 
Our knives for crushing wood

The future of heating

In times when raw materials such as natural gas and crude oil are becoming scarce, as well as global warming, wood chips for building heating are ever more important. They are a homegrown, crisis-proof and CO2-neutral fuel. As wood is also a renewable raw material, it will probably replace the limited alternative fuels, oil and gas, in the future. The choppers needed for crushing have already been in our product portfolio for decades and are used both in mobile choppers and in stationary drum choppers.
