Rotary shear for wood chips and biomass processing
Efficiently transform diverse biomass materials into uniform particles, optimizing feedstock conversion for bioenergy or biofuel production without the need for pre-drying.

Processes and Reduces Biomass Particle Size
The M24M Series Crumbler® Rotary Shear from Forest Concepts is engineered to streamline the reduction of biomass particle sizes. This medium-scale machine efficiently processes up to 2 wet tons per hour, making it ideal for transforming wood chips, agricultural residues, and renewable materials into precision-sized particles for bioenergy and biofuel production. The equipment operates using a rotary shear mechanism, which allows it to handle both high and low moisture feedstocks without pre-drying. With its modular design, the M24M Series integrates seamlessly into existing production lines and can be configured into single or stacked units. It offers energy-efficient operation with a choice of 20hp or 30hp motors and is controlled via PLC systems for enhanced automation and remote monitoring. Featuring multiple cutter-width options, the Crumbler® delivers uniform particle outputs tailored to specific processing requirements. With a small footprint and smooth operation, this machine is an excellent choice for sustainable material and renewable energy industries. Optional configurations and engineering support are available to meet unique processing needs.
