Brunette BioSizer®


The Brunette BioSizer® is a rugged high speed secondary grinder specifically designed for production of a fine consistent product. The Brunette BioSizer is built to be low maintenance with a high inertia rotor and fixed hammers.  Four rows of staggered hammers provide maximum bites per revolution.  This grinder allows for processing of oversized “bush-grind” hog fuel, trim blocks, and wood chips, all to be converted to a fine consistent product size for the biomass industry.

The main frame is protected with internal bolt-on replaceable wear liners. The grate has a progressive rectangular hole pattern and can be easily changed out to other hole patterns to suit required product size.
