Brunette/CBI Grizzly Mill Hog
This primary wood waste grinder is built to be the most rugged hog on the market. The Grizzly Mill’s high-interia, solid steel rotor has four alternating angled rows of striker bars to ensure even distribution of input material for balanced wear and maximum throughput.

This machine can break down large residuals from various sources, including cedar bark, green spruce bark, mill wood waste, demolition debris, butt ends, railroad ties and stringy bark, for easy processing into a high-quality product suitable for hog fuel, mulch or a biomass product.

Brunette BioSizer
The Brunette BioSizer is a high-speed secondary waste wood grinder designed to produce a uniform-sized output that is optimal for the biomass industry. The Brunette BioSizer is built to be low maintenance, with a high-inertia rotor and fixed hammers. With four rows of staggered hammers, this grinder efficiently processes oversized bush-grind hog fuel, trim blocks, wood chips and typical urban woodwaste, converting it all to fine, high-quality fiber suitable for various biomass products.

Brunette Machinery’s experience in manufacturing guarantees customers well-tested, heavy-duty machines that will produce high-quality product and deliver a long service life with low maintenance costs.
