Our Brunette BioSizer
is a rugged high- speed secondary wastewood grinder specifically manufactured to produce a fine, consistent product ideal for the biomass industry. This secondary grinder efficiently processes oversized “bush-grind”, trim blocks, wood chips, demolition material, and typical urban wood-waste, converting it all into uniform-sized fibres suitable for high-quality biomass fuel.
Built for low maintenance, the BioSizer features a high-inertia rotor with fixed, steel hammers. The four rows of staggered hammers are fitted with two-sided tungsten carbide coated striker bars for longevity. The rotor is mounted with B-Loks onto an oversized shaft supported by spherical bearings and installed in a spigot mounted steel bearing housing.
The Brunette BioSizer’s extreme duty main frame is line-bored for accuracy ensuring maximum bearing life. The swing-away anvil and grate are protected with shear pins to eliminate any damage due to processing of large pieces of metal or rock. Additional protection is provided by internal, replaceable, bolt-on wear liners.
We also manufacture and supply complementary equipment such as vibrating conveyors, disc scalping screens, E-Sweeps, and log singulators to help you get the most from your mill.
