M8M Series of Crumbler® Machines

Our research and lab rotary shear

Our M8M series of machines are ideally suited for research and lab use. They have a small footprint but are strong enough to handle a wide range of materials including wood chips, corn stover, switchgrass, bamboo, sage, hemp, agave, and more. The machine is capable of processing up to 1/2 green tons* per hour of your raw feedstocks into precision particles. 

CrumblerM8M-5e

Key features:

  • Processes both high and low moisture feedstocks (no pre-drying required)
  • Produces highly uniform particles to increase conversion efficiencies 
  • Low energy consumption
  • Choose from 1.5hp, 3hp, or 5hp 
  • PLC controls available
  • Modular for easy system integration (e.g., single unit, stacked, sequential)
  • Smooth, quiet operation
  • 8″ wide infeed capacity 
  • Small footprint – only 3.4′ X 2.7′
  • Standard power – 460VAC 3ph (220VAC 1ph and 110VAC 1ph available)
  • Multiple cutter-width processing heads available to tailor feedstocks for your process (standard widths are 1/4″, 3/16″, 1/8″, 1/16″, and 3/64″)
  • Processing head sold separately

* Throughput estimates based on ideal feedstocks and a skilled crew. Stated throughput is for green wood chips into 1/4″ feedstock particles. Throughput is inversely proportional to comminution ratio and final particle size. Other configurations and versions up to 1/8 and 1/4 tons per hour capacity are available. Dust control may be needed depending on moisture content and processing conditions.

Two M8M Crumbler® modules can be stacked in a tower configuration to your specifications.
