First milling test performed in order to obtain
heater grade chopped biomass:
Just about 30 Kg of biomass have been transformed.
The objective is to find a tool (power or engine) that chops
leaves and stems down to the correct size for burning in an
automatic biomass heater.
The point is, besides the size, that the product has to be
No further operations will have to be needed afterwards to
The result of this first test is not completely satisfactory
because the product presents different sizes. To achieve
a better result, sieving is necessary in order to discard
The problem starts with the machine's work: the chopping
is done on the same axis of insertion of the biomass: this
makes also the machine prone to choking. The final product
is part pulverized, part oversize.
Let's move over.
