Size reduction is a key processing step for feedstocks. Traditional methods include hammermills, grinders, and chippers. However, these methods typically are either limited to producing ½” and larger particles or require pre-drying of biomass at a substantial energy cost. Additionally, these methods may produce large amounts of fines with wide particle distributions and poor flowability.

Forest Concepts developed the Crumbler® rotary shear to address these common problems and produce a superior result.

We are pleased to offer our Crumbler® rotary shear in a range of models to suit your project. Each of our Crumbler® models can be customized as needed. Not sure which Crumbler® model is right for you? One of our engineers can help – just ask.
