Pilot-scale commercial rotary shear for biomass processing
Optimize your biomass processing with efficient particle size reduction, accommodating high and low moisture feedstocks without pre-drying, perfect for generating uniform, precision particles essential for biofuel and renewable material production.

Processes and Reduces Particle Size of Biomass
The M24P Crumbler® from Forest Concepts is a robust rotary shear machine designed for precision particle size reduction in bioenergy and biomass processing applications. This equipment excels with its ability to handle a wide variety of renewable materials, such as wood chips and corn stover, without the need for pre-drying, streamlining your processing workflow. Capable of processing up to 2 wet tons per hour, the M24P ensures efficient throughput while maintaining low energy consumption, courtesy of its adjustable 20hp or 30hp motors. Its PLC controls allow seamless integration into existing production lines, offering smooth and quiet operations within its compact 5′ x 6′ footprint.
Designed for pilot-scale operations, the M24P delivers consistent and uniform particle sizes, enhancing conversion efficiencies for products such as biochar or cellulosic ethanol. With multiple cutter-width options, the machine can easily be tailored to suit specific feedstock requirements, making it a versatile addition to your processing plant. Available power configurations include the standard 460VAC 3ph, with other options upon request.
To maintain optimal performance, the M24P can be paired with dust control systems, depending on feedstock moisture levels. Additionally, Forest Concepts provides comprehensive engineering support, ensuring your setup achieves maximum efficiency and meets your unique production needs.
