This cross between the HM 8-400 and HM 8-400 K, is specifically designed to produce larger wood chips, using the crane fed model’s rotor and blades.
The wider and thicker blades are able to make bigger and thicker chips that are typically used in Combined Heat and Power systems, or for larger biomass boilers that are designed to work with coarse fuel.
The 8-400 Green can also produce smaller chips by changing the screen to the desired size.
