Andritz wood pellet press

Development and optimisation of a wood pellet press for Andritz Feed and Biofuel

Andritz Group develops and produces production equipment for many industries, including machines for biomass production. DAVINCI has modernized, rethought and developed a new wood pellet press for Andritz Feed and Biofuel.

Easy transport of biomass

The purpose of the wood pellet press is to press fibrous material to fuel pellets and thereby reduce the capacity for transport between the production place and the power station. In this way, a large amount of biomass can more easily be transported between continents.

More effect, more energy effective

The original machine was 30 years old and outdated. The capacity of the machine was too small, and Andritz therefore wanted a larger and more effective pellet press. DAVINCI’s engineers rethought the original concept and developed a new product with doubled effect and which was 25% more energy effective.

The task consisted of design, dimensioning and 3D design engineering of the large casted and processed parts, which together make up the complete machine. Furthermore, the development process resulted in three patent applications related to the new pellet press.
