The Brunette BioSizer^TM is a rugged high speed wastewood grinder specifically designed for production of a fine consistent product.  The Brunette BioSizer^TM 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, wood chips, demolition materials, typical urban wood waste; all 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.
